OPA1678IDR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA1678IDR is a dual-channel audio operational amplifier manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It features rail-to-rail output capability and operates within a supply voltage range of 4.5 V to 36 V. Key electrical specifications include a gain-bandwidth product of 16 MHz, a slew rate of 9 V/µs, and an input voltage noise density of 4.5 nV/√Hz. The device draws 2 mA of operating current per channel and maintains a low input bias current of 10 pA. It supports an operating temperature range from -40°C to +85°C.
