The ISL54206A is a high-performance USB 2.0 audio switch from Intersil that supports low-distortion audio and high-precision USB 2.0 high-speed data (480Mbps) signal switching, which can be used in MP3 players and other portable devices.

EL9110 is a single channel differential receiver and equalizer. It contains a high speed differential receiver with 5 programmable poles. The outputs of these pole blocks are then summed into an output buffer. The equalization length is set with the voltage on a single pin. The EL9110 also contains a three-statable output, enabling multiple devices to be connected in parallel and used in a multiplexing application. The gain can be adjusted up or down by 6dB using the VGAIN control signal. In addition, a further 6dB of gain can be switched in to provide a matched drive into a cable. The EL9110 has a bandwidth of 150MHz and consumes just 33mA on ±5V supply. A single input voltage is used to set the compensation levels for the required length of cable. The EL9110 is available in the 16 Ld QSOP package and is specified for operation over the full -40°C to +85°C temperature range.

The ICL7660S is an upgraded version of the ICL7660, with an extended operating voltage range of up to 12V and lower supply current. No external diode is required for the ICL7660S. In addition, a Frequency Boost pin has been incorporated to enable the user to achieve lower output impedance despite using smaller capacitors. Critical parameters are guaranteed over the entire commercial, industrial and military temperature ranges. The ICL7660S performs supply voltage conversion from positive to negative for an input range of 1.5V to 12V, resulting in complementary output voltages of -1.5V to -12V. Only 2 non-critical external capacitors are needed for the charge pump and charge reservoir functions. The ICL7660S can be connected to function as a voltage doubler and will generate up to 22.8V with a 12V input. It can also be used as a voltage multiplier or voltage divider.

The ISL88011 through ISL88015 family of devices offer both fixed and/or adjustable voltage-monitoring that combine popular functions such as Power On Reset control, Watchdog Timer, Supply Voltage Supervision, and Manual Reset assertion in a small 5 Ld SOT-23 package.

The ISL21400 is a programmable temperature slope voltage reference that features a precision voltage reference and a temperature sensor. The output voltage varies linearly with temperature and can be programmed with adjustable slope and gain via an I2C bus.

ISL6535 is a high performance synchronous controller from ISL company, which is used for demanding DC/DC converter applications. It provides overcurrent fault protection and is designed to safely start up into prebiased output loads. The output voltage of the converter can be precisely regulated to as low as 0.597V, with a maximum tolerance of ±1% over the commercial temperature range, and ±1.5% over the industrial temperature range. ISL6535 provides simple, single feedback loop, voltage-mode control with fast transient response. It includes a triangle-wave oscillator that is adjustable from below 50kHz to over 1.5MHz. Full (0% to 100%) PWM duty cycle support is provided. The error amplifier features a 15MHz gain-bandwidth product and 6V/µs slew rate which enables high converter bandwidth for fast transient performance. The ISL6535's overcurrent protection monitors the current by using the rDS(ON) of the upper MOSFET which eliminates the need for a current sensing resistor.

The X9C102, X9C103, X9C104, X9C503 Digitally Controlled Potentiometer (XDCP™) is a solid-state potentiometer with 3-wire serial interface, 100 wiper tap points, wiper position stored in nonvolatile memory and recalled on power-up, 99 resistive elements, temperature compensated, ±20% end to end resistance, ±5V terminal voltages, low power CMOS, VCC = 5V, 3mA max. active current, 750µA max. standby current, 100 years register data retention, and 100,000 data changes per bit (Endurance).

The ISL1535 is a very low power dual channel differentiated amplifier designed for central office line driving for DMT ADSL2+ solutions. This device features a high drive capability of 600mA while consuming 5.2mA of supply current per amplifier from ±12V supplies. This driver achieves a typical distortion of less than -75dBc, at 1MHz into a 50Ω load. The ISL1535 is available in 28 Ld HTSSOP package. This device is specified for operation over the full -40°C to +85°C temperature range. The ISL1535 has two control pins, C0 and C1, per channel. With the selection of C0 and C1, the device can be set into full-IS power, 3/4-IS power, 1/2-IS power, and power-down disable modes. The ISL1535 maintains excellent distortion and load driving capabilities even in the lowest power settings. The ISL1535 has extended bandwidth, low THD and high slew rate for ADSL2+ applications.

The EL5170 and EL5370 are single and triple high bandwidth amplifiers with a fixed gain of 2. They are primarily targeted for applications such as driving twisted-pair lines in component video applications. The inputs signal can be in either single- ended or differential form but the outputs are always in differential form. The output common mode level for each channel is set by the associated VREF pin, which have a -3dB bandwidth of over 70MHz. Generally, these pins are grounded but can be tied to any voltage reference. All outputs are short circuit protected to withstand temporary overload condition. The EL5170 and EL5370 are specified for operation over the full -40°C to +85°C temperature range.

Intersil's ISL3179E is a ±15kV IEC61000 ESD Protected, 3.3V powered, single transceiver that meets both the RS-485 and RS-422 standards for balanced communication. This device has low bus currents (+220μA/-150μA), so it presents a “1/5 unit load” to the RS-485 bus. This allows up to 160 transceivers on the network without violating the RS-485 specification’s 32 unit load maximum, and without using repeaters. Receiver (Rx) inputs feature a “Full Fail-Safe” design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or terminated but undriven. Hot Plug circuitry ensures that the Tx and Rx outputs remain in a high impedance state while the power supply stabilizes.

The ISL28286 and ISL28486 are Dual and Quad channel micropower precision operational amplifiers optimized for single supply operation at 5V down to 2.4V.

The ISL12026 device is a micro power real time clock with timing and crystal compensation, clock/calender, power-fail indicator, two periodic or polled alarms, intelligent battery backup switching, and integrated 512 x 8 bit EEPROM configured in 16 Byte per page. The oscillator uses an external, low-cost 32.768kHz crystal. The real time clock tracks time with separate registers for hours, minutes, and seconds. The device has calendar registers for date, month, year and day of the week. The calendar is accurate through 2099, with automatic leap year correction.
