ISL12025 is a low power real-time clock with timing and crystal compensation, clock/calendar, 64-bit unique ID, power-fail indicator, two periodic or polled alarms, intelligent battery backup switching, CPU Supervisor and integrated 512 x 8-bit EEPROM, in a 16 Bytes per page format.

DG406, DG407 Single 16-Channel/Differential 8-Channel, CMOS Analog Multiplexers

EL5172 and EL5372 are single and triple high bandwidth amplifiers designed to extract the difference signal from noisy environments. They are primarily targeted for applications such as receiving signals from twisted-pair lines or any application where common mode noise injection is likely to occur. The EL5172 and EL5372 are stable for a gain of one and requires two external resistors to set the voltage gain. The output common mode level is set by the reference pin (VREF), which has a -3dB bandwidth of over 120MHz. Generally, this pin is grounded but it can be tied to any voltage reference. The output can deliver a maximum of ±60mA and is short circuit protected to withstand a temporary overload condition. The EL5172 is available in the 8 Ld SOIC and 8 Ld MSOP packages and the EL5372 in a 24 Ld QSOP package. Both are specified for operation over the full -40°C to +85°C temperature range.

ISL54003, ISL54005, ISL54006 are integrated audio power amplifier systems from Intersil, which combine a mono BTL amplifier and stereo headphone amplifiers in a single device. The devices are designed to operate from a single +2.7V to +5V power supply and can drive 8Ω mono speaker and 16Ω or 32Ω headphone speakers.

ISL8105 and ISL8105A are single-phase PWM controllers with integrated MOSFET gate drivers for synchronous buck converters. The devices operate from +5V or +12V bias supply voltage. ISL8105 integrates a linear regulator, boot diode, and N-Channel MOSFET gate drivers, reducing external component count and board space requirements. These features make the IC suitable for a wide range of applications. Utilizing voltage-mode control, the output voltage can be precisely regulated to as low as 0.6V. The 0.6V internal reference features a maximum tolerance of ±1.0% over the commercial temperature range, and ±1.5% over the industrial temperature range. Two fixed oscillator frequency versions are available; 300kHz (ISL8105 for high efficiency applications) and 600kHz (ISL8105A for fast transient applications). The ISL8105 features the capability of safe start-up with pre-biased load. It also provides overcurrent protection by monitoring the ON-resistance of the bottom-side MOSFET to inhibit PWM operation appropriately. During start-up interval, the resistor connected to BGATE/BSOC pin is employed to program overcurrent protection condition. This approach simplifies the implementation and does not deteriorate converter efficiency.

The Intersil ICL32xxE devices are 3.0V to 5.5V powered RS-232 transmitters/receivers which meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Additionally, they provide ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are PDAs, Palmtops, and notebook and laptop computers where the low operational, and even lower standby, power consumption is critical.

The ISL28276 and ISL28476 are Dual and Quad channel micropower precision operational amplifiers optimized for single supply operation at 5V and can operate down to 2.4V. They feature an Input Range Enhancement Circuit (IREC) which enables both parts to maintain CMRR performance for input voltages equal to the positive and negative supply rails. The input signal is capable of swinging 0.5V above a 5.0V supply (0.25V for a 2.4V supply) and to within 10mV from ground. The output operation is rail to rail. The both parts draw minimal supply current while meeting excellent DC-accuracy, AC-performance, noise and output drive specifications. Offset current, voltage and current noise, slew rate, and gain-bandwidth product are all two to ten times better than other micropower op-amps with equivalent supply current ratings. The ISL28276 and ISL28476 can be operated from one lithium cell or two Ni-Cd batteries. The input range includes both positive and negative rail.

EL2126 is an ultra-low noise, wideband amplifier that runs on half the supply current of competitive parts.

The ISL22426 integrates two digitally controlled potentiometers (DCP) and non-volatile memory on a monolithic CMOS integrated circuit. It features low noise, low power, SPI bus interface, and can be used in a wide range of applications including control, parameter adjustments, and signal processing.

The Intersil ISL54000, ISL54001, ISL54002 are integrated audio power amplifier systems that combine stereo BTL 8Ω amplifiers in a single package

ISL8104 8V to 14V, Single-Phase Synchronous Buck Pulse-Width Modulation (PWM) Controller With Integrated Gate Drivers

The EL5166 and EL5167 amplifiers are 1.4GHz current feedback amplifiers with enable function, suitable for high-speed video, monitor, RF, and IF frequency designs. They have a high bandwidth of 1.4GHz, a supply current of just 8.5mA, and can operate from a single supply voltage of 5V to 12V.
