The LTC6912 is a family of dual channel, low noise, digitally programmable gain amplifiers (PGA) that are easy to use and occupy very little PC board space. The gains for both channels are independently programmable using a 3-wire SPI interface to select voltage gains of 0, 1, 2, 5, 10, 20, 50, and 100V/V (LTC6912-1 ); and 0, 1, 2, 4, 8, 16, 32, and 64V/V (LTC6912-2). All gains are inverting. The LTC6912 family consists of 2 matched amplifiers with rail-to-rail outputs. When operated with unity gain, they will also process rail-to-rail input signals. A half-supply reference generated internally at the AGND pin supports single power supply applications.

The LTC1968 is a precision wide bandwidth RMS-to-DC converter with 0.02% linearity for simple system calibration.

The LT1497 is a dual current feedback amplifier that features low power, high output drive, excellent video characteristics and outstanding distortion performance. From a low 7mA maximum supply current per amplifier, the LT1497 drives ±100mA with only 1.9V of headroom. Twisted pairs can be driven differentially with –70dBc distortion up to 1MHz for ±40mA peak signals. The LT1497 is available in a low thermal resistance 16-pin SO package for operation with supplies up to ±15V. For ±5V operation the device is also available in a low thermal resistance SO-8 package.

The LT3466-1 is a dual switching regulator that combines a white LED driver and a boost converter in a low profile, small footprint (3mm × 3mm × 0.75mm) DFN package. The LED driver can be configured to drive up to 10 White LEDs in series and the boost converter can be used for generating the LCD bias voltages or driving a secondary OLED display. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors and expensive factory calibration. The LT3466-1 provides independent dimming and shut- down control of the two converters. The operating fre- quency can be set with an external resistor over a range of 0.5MHz to 2MHz.

LTC1418 is a low power, 200ksps, 14-bit A/D converter with serial and parallel I/O

The LTC ®1066-1 is an 8th order elliptic lowpass filter which simultaneously provides clock-tunability and DC accuracy. The unique and proprietary architecture of the filter allows 14 bits of DC gain linearity and a maximum of 1.5mV DC offset. An external RC network is used to set the filter's cutoff frequency and phase. The device has high output swing, capable of driving a 1kΩ load, and features 0.02% THD or better distortion.

The LTC4440 4440f High Speed, High Voltage High Side Gate Driver features a wide operating VIN range of up to 80V, a rugged architecture tolerant of 100V VIN transients, a powerful 1.5Ω driver pull-down, a powerful 2.4A peak current driver pull-up, 7ns fall time driving 1000pF load, 10ns rise time driving 1000pF load, drives standard threshold MOSFETs, TTL/CMOS compatible inputs with hysteresis, input thresholds are independent of supply, undervoltage lockout, low profile (1mm) SOT-23 (ThinSOT) TM and thermally enhanced 8-pin MSOP packages.

The LT1008 is a precision operational amplifier from National Semiconductor that is capable of extremely low bias currents, microvolt offset voltage, low voltage and current noise, and low power dissipation. It also has extremely high common mode and power supply rejection ratios, and can deliver 5mA of load current with high voltage gain.
