TLV320ADC5140IRTWR 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) to AVSS.
2 AREG power_out Analog on-chip regulator output (1.8 V nominal) or external analog power input; decoupling capacitor required.
3 VREF power_in Analog reference voltage filter output; requires minimum 1-µF capacitor to AVSS.
4 AVSS power_in Analog ground; short directly to board ground plane.
5 MICBIAS output Microphone bias voltage output selectable to VREF, VREF × 1.096, or AVDD.
6 IN1P_GPI1 input Analog input 1P positive or general-purpose digital input 1 for microphone data or PLL clock source.
7 IN1M_GPO1 bidirectional Analog input 1M negative or general-purpose digital output 1 for microphone clock or interrupt output.
8 IN2P_GPI2 input Analog input 2P positive or general-purpose digital input 2 for microphone data or PLL clock source.
9 IN2M_GPO2 bidirectional Analog input 2M negative or general-purpose digital output 2 for microphone clock or interrupt output.
10 IN3P_GPI3 input Analog input 3P positive or general-purpose digital input 3 for microphone data or PLL clock source.
11 IN3M_GPO3 bidirectional Analog input 3M negative or general-purpose digital output 3 for microphone clock or interrupt output.
12 IN4P_GPI4 input Analog input 4P positive or general-purpose digital input 4 for microphone data or PLL clock source.
13 IN4M_GPO4 bidirectional Analog input 4M negative or general-purpose digital output 4 for microphone clock or interrupt output.
14 SHDNZ input Device hardware shutdown and reset control input (active low); assert low for shutdown.
15 ADDR1_MISO bidirectional I2C slave address A1 strapping input or SPI slave data output (MISO); open-drain output in I2C mode.
16 ADDR0_SCLK input I2C slave address A0 strapping input or SPI serial bit clock input (SCLK).
17 SCL_MOSI input I2C clock line (SCL) or SPI slave data input (MOSI); open-drain in I2C mode.
18 SDA_SSZ bidirectional I2C data line (SDA) or SPI slave select (SSZ); open-drain bidirectional in I2C mode.
19 IOVDD power_in Digital I/O power supply (1.8 V or 3.3 V nominal) to VSS thermal pad.
20 GPIO1 bidirectional General-purpose digital I/O with configurable function (output, interrupt, clock input, data input/output).
21 SDOUT output Audio serial data output for TDM, I²S, or LJ interface.
22 BCLK bidirectional Audio serial bit clock for TDM, I²S, or LJ interface (input in slave mode, output in master mode).
23 FSYNC bidirectional Audio serial frame synchronization signal for TDM, I²S, or LJ interface (input or output).
24 DREG power_out Digital regulator output (1.5 V nominal) for digital core supply; decoupling capacitor required.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
