Product Overview
The OPA1692 is a Texas Instruments dual audio operational amplifier in the Signal Chain category. Its dual amplifier pinout provides channels A and B, supporting two audio signal paths in one 8-pin package. The device operates from a 3.5 V to 36 V single supply or from ±1.75 V to ±18 V split supplies, with a specified temperature range of -40°C to 125°C and recommended operating temperature from -40°C to 85°C.
Audio-path performance is defined by 4.2 nV/√Hz typical input voltage noise density at 1 kHz, 130 nVPP typical noise from 0.1 Hz to 10 Hz, and 3.9 µVPP typical noise from 20 Hz to 20 kHz. Distortion data includes -127 dB typical THD+N at 1 kHz and -118 dB typical THD+N at 20 kHz with G=1, RL=2 kΩ, and VO=3 VRMS.
Package options are 8-pin VSSOP (DGK), 3.00 mm x 3.00 mm, and 8-pin SOIC (D), 4.90 mm x 3.91 mm. Assembly and thermal review can use the listed junction-to-ambient values of 162.2°C/W for VSSOP and 123.6°C/W for SOIC. Output-related specifications include ±50 mA drive capability, 200 pF typical capacitive load drive, continuous short-circuit duration under the stated condition, and output swing within 200 mV of the rails with a 2 kΩ load.
