TLV320ADC6140IRTWR from Texas Instruments, in a WQFN-24(4x4). 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 AVDD power_in Analog power supply, 1.8 V or 3.3 V nominal; 3.0 V to 3.6 V for 3.3 V operation and 1.7 V to 1.9 V for 1.8 V operation.
2 AREG power_out Analog on-chip regulator output for the analog supply (1.8 V nominal), or an input for external 1.8 V analog power when the internal regulator is shut down.
3 VREF power_in Analog reference voltage filter node; requires a minimum 1-µF capacitor from VREF to AVSS.
4 AVSS power_in Analog ground; short directly to the board ground plane and keep within 0.2 V of VSS (thermal pad).
5 MICBIAS output Microphone bias output; the level is set by MBIAS_VAL to VREF, VREF x 1.096, or AVDD.
6 IN1P_GPI1 passive Analog input 1P or general-purpose digital input 1; voltage range is -0.3 V to AVDD + 0.3 V relative to VSS (thermal pad).
7 IN1M_GPO1 passive Analog input 1M or general-purpose digital output 1 (also used for PDM clock or interrupt); analog input voltage range is -0.3 V to AVDD + 0.3 V relative to AVSS.
8 IN2P_GPI2 passive Analog input 2P or general-purpose digital input 2; voltage range is -0.3 V to AVDD + 0.3 V relative to VSS (thermal pad).
9 IN2M_GPO2 passive Analog input 2M or general-purpose digital output 2 (also used for PDM clock or interrupt); analog input voltage range is -0.3 V to AVDD + 0.3 V relative to AVSS.
10 IN3P_GPI3 passive Analog input 3P or general-purpose digital input 3; voltage range is -0.3 V to AVDD + 0.3 V relative to VSS (thermal pad).
11 IN3M_GPO3 passive Analog input 3M or general-purpose digital output 3 (also used for PDM clock or interrupt); analog input voltage range is -0.3 V to AVDD + 0.3 V relative to AVSS.
12 IN4P_GPI4 passive Analog input 4P or general-purpose digital input 4; voltage range is -0.3 V to AVDD + 0.3 V relative to VSS (thermal pad).
13 IN4M_GPO4 passive Analog input 4M or general-purpose digital output 4 (also used for PDM clock or interrupt); analog input voltage range is -0.3 V to AVDD + 0.3 V relative to AVSS.
14 SHDNZ input Device hardware shutdown and reset, active low; digital input referenced to IOVDD (maximum IOVDD + 0.3 V).
15 ADDR1_MISO bidirectional In I2C mode, I2C slave address A1 pin; in SPI mode, SPI slave output pin.
16 ADDR0_SCLK input In I2C mode, I2C slave address A0 pin; in SPI mode, SPI serial bit clock input.
17 SCL_MOSI input In I2C mode, clock pin for the I2C control bus; in SPI mode, SPI slave input pin.
18 SDA_SSZ bidirectional In I2C mode, data pin for the I2C control bus; in SPI mode, SPI slave-select pin.
19 IOVDD power_in Digital I/O power supply, 1.8 V or 3.3 V nominal; 3.0 V to 3.6 V for 3.3 V operation and 1.65 V to 1.95 V for 1.8 V operation.
20 GPIO1 bidirectional General-purpose digital input/output 1, referenced to IOVDD; multipurpose functions include PDM microphone clock or data, PLL input clock source, and interrupt output.
21 SDOUT output Audio serial data interface bus output.
22 BCLK bidirectional Audio serial data interface bit clock.
23 FSYNC bidirectional Audio serial data interface frame synchronization signal.
24 DREG power_out Digital regulator output for the digital core supply, 1.5 V nominal.
25 VSS passive Exposed pad (from the footprint; not named in the datasheet pin table).
