Overview
The LTC6362IDD#PBF, produced by Analog Devices Inc., is a precision, low power rail-to-rail input/output differential op amp optimized for driving low power Successive Approximation Register (SAR) Analog-to-Digital Converters (ADCs). This amplifier is characterized by its low noise, low offset voltage, and low input bias current, making it suitable for various applications in noisy industrial environments. It operates with a single supply voltage ranging from 2.8V to 5.25V and draws only 1mA of supply current in active operation, with a shutdown mode that reduces current consumption to 70μA.
