Texas Instruments · Analog To Digital Converters (ADCs) · WQFN-24-EP(4x4)

TLV320ADC3140IRTWT from Texas Instruments, in a WQFN-24-EP(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; 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).
2 AREG power_out Analog on-chip regulator output voltage for analog supply (1.8 V, nominal) or external analog power input (1.8 V, nominal). Requires bypass capacitor to AVSS.
3 VREF passive Analog reference voltage filter output. Requires external bypass capacitor to AVSS.
4 AVSS power_in Analog ground. Short this pin directly to the board ground plane.
5 MICBIAS power_out Microphone bias output for biasing external analog microphones.
6 IN1P_GPI1 bidirectional Analog input 1P (positive analog audio input) or general-purpose digital input 1. Multipurpose functions include digital microphone data, PLL input clock source, and so forth.
7 IN1M_GPO1 bidirectional Analog input 1M (negative analog audio input) or general-purpose digital output 1. Multipurpose functions include digital microphone clock, interrupt, and so forth.
8 IN2P_GPI2 bidirectional Analog input 2P or general-purpose digital input 2 (multipurpose: digital microphone data, PLL input clock, etc.).
9 IN2M_GPO2 bidirectional Analog input 2M or general-purpose digital output 2 (multipurpose: digital microphone clock, interrupt, etc.).

15 ADDR1_MISO bidirectional For I2C operation: I2C slave address A1 pin. For SPI operation: SPI slave output pin (MISO).
16 ADDR0_SCLK input For I2C operation: I2C slave address A0 pin. For SPI operation: SPI serial bit clock (SCLK).
17 SCL_MOSI input For I2C operation: clock pin for I2C control bus (SCL). For SPI operation: SPI slave input pin (MOSI).
18 SDA_SSZ bidirectional For I2C operation: data pin for I2C control bus (SDA). For SPI operation: SPI slave-select pin (SSZ, active low).
19 IOVDD power_in Digital I/O power supply (1.8 V or 3.3 V, nominal).
20 GPIO1 bidirectional General-purpose digital input/output 1. Multipurpose functions such as digital microphones clock or data, PLL input clock source, interrupt, and so forth.
21 SDOUT output Audio serial data interface bus output (TDM / I2S / LJ data output).
22 BCLK bidirectional Audio serial data interface bus bit clock. Can be input (slave) or output (master) depending on configuration.
23 FSYNC bidirectional Audio serial data interface bus frame synchronization signal. Can be input (slave) or output (master) depending on configuration.
24 DREG power_out Digital regulator output voltage for digital core supply (1.5 V, nominal). Requires bypass capacitor to VSS.
