TPA1834

30-V, 1.1-MHz, High-Precision, Low-Power, Zero-Drift Op Amps

Overview

The TPA183x is the mirco-power, zero-drift amplifier with maximum 18-μV low-offset voltage and stable frequency response for the high-precision sensing applicaiton that also requires low standby power.

The TPA183x series of devices provide rail-to-rail input and output. These devices have excellent AC performance with 1.1-MHz bandwidth, 0.7-V/us slew rate while only drawing 140-uA quiescent current per amplifier.

All versions can be operated over the industrial temperature range of −40°C to +125°C.
