MUSES72323V-TE1

Audio Special Purpose Overview

The MUSES72323V-TE1 is a high-quality audio volume control IC designed for ±18V operation. It features a 3-wired serial interface and provides independent left/right channel volume adjustment with 0.25dB steps from 0 to -111.75dB, plus gain settings up to +21dB. The device includes soft-step and zero-cross detection circuits to minimize audible noise during adjustments. It requires external operational amplifiers for output buffering and operates within an ambient temperature range of -40°C to +85°C.

Audio Special Purpose Feature Summary

• ±18V analog supply voltage with low output noise and distortion characteristics
• 3-wired serial bus control with selectable chip address for multi-chip systems
• Independent L/R channel volume control (0 to -111.75dB) and gain control (+21dB)
• Soft-step circuit and zero-cross detection to reduce zipper noise and switching artifacts

Audio Special Purpose Applications

• High-end Hi-Fi audio equipment
• Professional audio processing systems
• Audio tone processors requiring precise analog gain control

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix TE1 corresponds to the SSOP32 package with Sn-2Bi terminal finish and tape/reel packaging containing 100 pieces per reel. Confirm RoHS compliance and halogen-free status as specified in the manufacturer's ordering information table before finalizing procurement specifications.

Audio Special Purpose Selection Notes

Select this component when designing circuits requiring high-voltage analog signal handling up to ±18V. Ensure the design accommodates external op-amps for output buffering, as the IC does not drive loads directly. Verify that the digital control logic supports the required 3-wired serial protocol and voltage levels (3.0V to 5.5V).

Audio Special Purpose Part Context

This part belongs to the MUSES series of high-performance audio components manufactured by Nisshinbo Micro Devices Inc. It serves as a precision analog volume controller, distinct from power amplifiers or digital mixers. The V-TE1 designation indicates the specific package and taping configuration for surface-mount assembly.
