MUSES72320V-TE2

Audio Special Purpose Overview

The MUSES72320V-TE2 is a dual-channel electronic volume controller designed for high-end audio equipment. It operates on a supply voltage of ±8.5V to ±18V with an operating supply current of 2mA. The device features a resistance ladder circuit providing low noise and distortion, controlled via a three-wired serial interface (SPI compatible). Volume attenuation ranges from 0dB to -111.5dB in 0.25dB steps, while gain control spans +31.5dB to 0dB in 0.5dB steps. It includes selectable chip addressing for up to eight units on a single bus, zero-cross detection, and is housed in a 32-LSSOP package.

Audio Special Purpose Procurement Notes

Verify the TE2 suffix indicates tape and reel packaging format when sourcing. Confirm moisture sensitivity level (MSL) requirements for surface mount assembly processes. Ensure the specific revision matches design specifications as datasheet versions may vary.

Audio Special Purpose Selection Notes

Select this component for designs requiring precise digital volume control with minimal signal degradation. Ensure external operational amplifiers are chosen to match the low noise characteristics, as output noise depends on external components. Verify power supply stability within the ±8.5V to ±18V range for optimal performance.
