OPA1632DR Description

Short technical summary and product information.

The OPA1632DR from Texas Instruments is a high-performance, fully differential audio amplifier (FDA). It is engineered to drive high-fidelity audio analog-to-digital converters (ADCs) or serve as a predriver for class-D amplifiers. This device delivers exceptional audio quality, characterized by ultra-low distortion of 0.000028% and a low noise density of 1.25 nV/√Hz, ensuring a maximum signal-to-noise ratio.

Key electrical specifications include a high gain bandwidth product of 180 MHz and a fast slew rate of 72 V/µs, contributing to its low distortion performance. The fully differential architecture allows for easy conversion of single-ended inputs to balanced differential outputs, which helps reduce even-order harmonics and common-mode noise interference. The OPA1632DR operates over a wide supply voltage range of ±2.5 V to ±15 V.

This amplifier is available in an 8-pin SOIC package. It is designed to operate within an ambient temperature range of -40°C to +85°C. A shutdown feature is included to conserve power when the device is not in use. The OPA1632DR is suitable for applications requiring superior audio performance and noise immunity.
