Product Overview
The OPA1612 is a Texas Instruments dual operational amplifier built as a bipolar-input audio operational amplifier for Signal_Chain use. The family is specified with bipolar inputs, unity-gain stability, and ±30 mA output drive capability, supporting audio circuits that require low noise and controlled distortion performance.
Noise and distortion specifications include 1.1 nV/√Hz typical input voltage noise density at 1 kHz, 1.2 μVPP typical input voltage noise from 20 Hz to 20 kHz, and 1.7 pA/√Hz typical input current noise density at 1 kHz. Distortion data includes 0.000015% typical THD+N at G=+1, f=1 kHz, and VO=3 VRMS, plus specified SMPTE/DIN, DIM30, and CCIF intermodulation distortion values.
The device operates from a recommended 4.5 V to 36 V total supply, equivalent to ±2.25 V to ±18 V. OPA1612 package options are SOIC-8 and SON-8; the DRG SON-8 version requires the exposed thermal die pad to be connected to V-.
