Overview
The OPA1632DGN is a high-performance, fully differential audio operational amplifier produced by Texas Instruments. This device is designed to drive high-performance audio analog-to-digital converters (ADCs) or serve as a predriver for class-D amplifiers. It delivers excellent audio quality, characterized by very low noise, large output voltage swing, and high current drive. The OPA1632DGN operates over a wide supply range of ±2.5 V to ±15 V and is available in an 8-pin HVSSOP package with a thermally-enhanced PowerPAD™ for improved thermal performance.
