Description of LTC6362

The LTC6362CDD is a low-power, low-noise differential operational amplifier with rail-to-rail input and output swings, which has been optimized specifically for driving low-power SAR ADCs. The LTC6362CDD only absorbs 1mA of power supply current during active operation and features A shutdown mode in which current consumption is reduced to 70μA.

The amplifier can be configured to convert a single-ended input signal into a differential output signal and can operate in either inverting or non-inverting configurations.

The low offset voltage, low input bias current and a stable high-impedance configuration make this amplifier not only suitable for use as an ADC driver, but also in the forward signal link to convert a precise sensor signal into a balanced (differential) signal that can be processed in a noisy industrial environment.

The LTC6362CDD is available in a compact 3mm x 3mm 8-pin leadless DFN package and can operate within a temperature range of -40°C to 125°C, while ensuring compliance with specified performance indicators.
