35dB — what that means in a consumer audio path
The 35dB of noise reduction is the headline performance figure. In a typical portable audio chain — say, a DAC feeding a headphone driver — this IC sits in the analog path and knocks down broadband hiss and power-supply artifacts by that amount. Enough to clean up a noisy ground plane or a marginal LDO without redesigning the power tree. The 2-channel count matches stereo line-level or headphone outputs.
Package and footprint reality
The 6-UCSP is a 6-ball WFBGA/CSPBGA. The Tape & Reel supply (Cut Tape also available) feeds pick-and-place lines directly.
Lifecycle and sourcing
The MAX9892ERT+T carries an Active lifecycle status with ROHS3 compliance. Sourced through independent distribution; availability and current pricing confirmed against an RFQ.
