OPA4134UA

Instrumentation, Op Amps, Buffer Amps Overview

The OPA4134UA is a quad high-performance audio operational amplifier from the SoundPlus series, manufactured by Texas Instruments. It features FET inputs and operates on dual or single power supplies ranging from 5V to 36V (±2.5V to ±18V). Key electrical parameters include an 8 MHz gain-bandwidth product, a 20 V/µs slew rate, and a maximum input offset voltage of 2 mV. The device draws 10 mA of supply current and provides 40 mA output current per channel. It is housed in a 14-pin SOIC package and functions within a temperature range of -40°C to +85°C.
