Stereo output with depop and differential inputs
The MAX9719AETE+: Two-channel (stereo) output with differential inputs rejects common-mode noise picked up on long input traces between the codec and the amplifier — useful in mixed-signal boards where the audio path crosses a digital bus. The depop circuitry suppresses turn-on/turn-off clicks without external muting FETs, saving two BOM positions per channel. Integrated thermal protection and a shutdown pin let the system controller pull the amplifier into low-power idle when no audio is present, keeping the enclosure temperature rise within the plastic housing rating.
16-TQFN exposed-pad package — thermal and layout notes
Housed in a 16-lead TQFN with exposed pad (4x4 mm body), the MAX9719AETE+ requires a thermal land on the PCB to pull heat from the output stage into the ground plane. Surface-mount assembly on standard reflow profiles — the 4x4 mm body is small enough to fit tight channel spacing in a multi-channel audio board.
Sourcing posture for volume and spot buys
RoHS3 compliance and the industrial temperature grade are confirmed on the label; no additional REACH or UL documentation is carried in the standard spec package.
