Texas Instruments OPA1678IDR is a dual audio operational amplifier designed for low-noise, low-distortion signal conditioning. It combines 4.5nV/√Hz typical input voltage noise, 0.0001% typical THD+N at 1kHz, a 16MHz gain-bandwidth product, and a 9V/µs slew rate.
The device supports single supplies from 4.5V to 36V or dual supplies from ±2.25V to ±18V. Unity-gain stability, rail-to-rail output capability, and low input bias current make it suitable for audio buffers, preamplifiers, active filters, and integrator circuits. Independent internal amplifier circuitry helps minimize interaction between channels.
The exact OPA1678IDR ordering model is supplied in an 8-pin SOIC package with 2,500 devices per reel. TI lists it as Active, with an ordering temperature range of −40°C to +85°C.
