TPA5571Q-S5TR-S

Instrumentation, Op Amps, Buffer Amps Overview

The TPA5571Q-S5TR-S is a single-channel, zero-drift operational amplifier in an SOT23-5 package. It operates on a single supply of 2.7 V to 5.5 V or dual supplies of ±1.35 V to ±2.75 V. Key electrical parameters include a maximum input offset voltage of ±45 μV and a drift of ±0.01 µV/°C. The device features a gain-bandwidth product of 15 MHz and a slew rate of 5 V/μs. Quiescent current is typically 1 mA per amplifier. Input noise density is 10 nV/√Hz at 1 kHz. It supports rail-to-rail input and output capabilities.
