PCM1742E

Texas Instruments · ADCs/DACs - Special Purpose · SSOP-16-150mil

PCM1742E from Texas Instruments, in a SSOP-16-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BCK input Audio data bit clock input; Schmitt-trigger input, 5-V tolerant.
2 DATA input Audio data digital input; Schmitt-trigger input, 5-V tolerant.
3 LRCK input L-channel and R-channel audio-data latch-enable input; Schmitt-trigger input, 5-V tolerant.
4 DGND power_in Digital ground.
5 VDD power_in Digital power supply, 3.3 V nominal (3.0 V to 3.6 V per the electrical characteristics).
6 VCC power_in Analog power supply, 5 V nominal (4.5 V to 5.5 V per the electrical characteristics).
7 VOUTL output Analog output for the L-channel.
8 VOUTR output Analog output for the R-channel.
9 AGND power_in Analog ground.
10 VCOM passive Common voltage decoupling pin.
11 ZEROR/ZEROA output Zero-flag output for the R-channel, or zero-flag output for L- and R-channel when used as ZEROA.
12 ZEROL/NA output Zero-flag output for the L-channel, or no assignment (NA) when unused.
13 MD input Mode control data input; Schmitt-trigger input with internal pulldown, 5-V tolerant.
14 MC input Mode control clock input; Schmitt-trigger input with internal pulldown, 5-V tolerant.
15 ML input Mode control latch input; Schmitt-trigger input with internal pulldown, 5-V tolerant.
16 SCK input System clock input; Schmitt-trigger input, 5-V tolerant.
