ADAU7118ACPZRL from Analog Devices, in a LFCSP-16(3x3). 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 PDM_CLK0 output PDM output clock 0, with output drive strength set by PDM_CLK0_DS (2.5 mA to 15 mA at 3.3 V).
2 PDM_DAT0 input PDM input data 0 from the digital microphone(s) on this channel pair.
3 PDM_DAT1 input PDM input data 1 from the digital microphone(s) on this channel pair.
4 PDM_CLK1 output PDM output clock 1, with output drive strength set by PDM_CLK1_DS (2.5 mA to 15 mA at 3.3 V).
5 PDM_DAT2 input PDM input data 2 from the digital microphone(s) on this channel pair.
6 PDM_DAT3 input PDM input data 3 from the digital microphone(s) on this channel pair.
7 SCL input I2C serial clock input; the pin is open-drain and requires pull-up resistors to IOVDD.
8 SDA bidirectional I2C serial data; the pin is open-drain and requires pull-up resistors to IOVDD.
9 FSYNC input I2S/TDM frame sync or left/right clock, used as the slave frame sync input.
10 BCLK input I2S/TDM bit clock input, which the device uses as a slave clock; BCLK removal automatically powers the device down.
11 SDATA output I2S/TDM serial data output, with output drive strength set by SDATA_DS (2.5 mA to 15 mA at 3.3 V).
12 ADDR/CONFIG input I2C address or standalone hardware configuration selection, set by tying the pin to IOVDD, GND, through a 47 kΩ resistor, or leaving it open.
13 EN input Chip enable; grounding this pin disables the device into low power mode, and applying IOVDD enables normal operation.
14 DVDD power_in Internal core digital power supply, 1.10 V to 1.98 V.
15 GND power_in Ground.
16 IOVDD power_in Digital input/output power supply, 1.70 V to 3.63 V.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
