Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The OPA1633DR is a fully differential audio amplifier designed to drive high-performance audio analog-to-digital converters (ADCs) or serve as a pre-driver for Class D amplifiers.

The OPA1633DR can achieve outstanding audio quality, extremely low noise, large output voltage swing and high current drive. The OPA1633DR features an outstanding gain bandwidth of 200MHz and an ultra-fast slew rate of 80V/µs, enabling extremely low distortion. A very low input voltage noise of 1.1nV/√Hz can further provide a larger signal-to-noise ratio and dynamic range.
