Packaged in the SOT-23-8, it is one of TI's smallest dual op-amps at 1\/4 the size of a conventional SO-8. The CMOS architecture provides low 0.2 pA input bias current, making it ideal for high-impedance sensor interfaces. With 3 MHz gain-bandwidth, 1.2 V\/us slew rate, and rail-to-rail output swing, it operates from 2.5V to 5.5V single supply. The input common-mode range includes ground, enabling true single-supply operation. The dual channels feature independent circuitry for minimum crosstalk.","working_principle":"The OPA2337 uses a CMOS input stage providing ultra-low input bias current (0.2 pA typical) and high input impedance, followed by a folded-cascode gain stage and a rail-to-rail output stage. The output stage uses complementary P-channel and N-channel MOSFETs to swing within millivolts of both supply rails, maximizing dynamic range. The device is unity-gain stable with 120 dB open-loop gain and 90 dB CMRR. In the SOT-23-8 package, the two amplifier channels are completely independent with separate input and output pins, minimizing crosstalk even during overload conditions.","pin_description":"
