THS4140CDGKR

Instrumentation, Op Amps, Buffer Amps Overview

The THS4140CDGKR is a fully differential amplifier manufactured by Texas Instruments, featuring a high slew rate of 450 V/us and a single channel configuration. It operates within a supply voltage range of 4 V to 33 V, drawing 13.2 mA of quiescent current. The device provides an output current of 85 mA per channel with a common-mode rejection ratio (CMRR) between 75 dB and 84 dB. Input characteristics include a bias current of 15 uA and an offset voltage of 7 mV. It functions reliably across temperatures from -40 C to +85 C and is housed in an SOIC-8 surface-mount package.
