TAS2505IRGER from Texas Instruments, in a VQFN-24-EP(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 | SPI_SEL | input | Select SPI (high) or I2C (low) digital interface mode. |
| 2 | RST | input | Active low reset for logic, state machine, and digital filter. |
| 3 | AINL | input | Analog single-ended left input to mixer and headphone driver, 0.5 VRMS full-scale. |
| 4 | AINR | input | Analog single-ended right input to mixer and headphone driver, 0.5 VRMS full-scale. |
| 5 | NC | unconnected | No connection; leave unconnected. |
| 6 | AVSS | power_in | Analog ground reference, 0V. |
| 7 | AVDD | power_out | Analog core power supply, 1.5V to 1.95V. |
| 8 | LDO_SEL | input | Hardware control pin; connect to ground for proper device operation. |
| 9 | SPKM | output | Class D speaker driver inverting output in BTL configuration, minimum 4Ω load. |
| 10 | SPKVDD | power_out | Class D speaker driver power supply, 2.7V to 5.5V. |
| 11 | SPKVSS | power_in | Class D speaker driver power supply ground, 0V reference. |
| 12 | SPKP | output | Class D speaker driver non-inverting output in BTL configuration, minimum 4Ω load. |
| 13 | DIN | input | Audio serial data bus input for I2S, DSP, or TDM digital audio interface. |
| 14 | WCLK | bidirectional | Audio word clock; configurable as master output or slave input via registers. |
| 15 | BCLK | bidirectional | Audio bit clock; configurable as master output or slave input via registers. |
| 16 | MCLK | input | Master clock input or PLL reference for clock multiplier; 50 MHz maximum. |
| 17 | MISO | output | SPI serial data output when SPI_SEL pin is high. |
| 18 | GPIO/DOUT | tri_state | Programmable GPIO or secondary I2S data output with tri-state high-impedance capability. |
| 19 | SCL/SSZ | input | I2C serial clock (SPI_SEL low) or SPI chip select signal (SPI_SEL high). |
| 20 | SDA/MOSI | input | I2C serial data input (SPI_SEL low) or SPI master-out-slave-in (SPI_SEL high). |
| 21 | SCLK | input | SPI serial clock input; used only when SPI_SEL pin is high. |
| 22 | IOVDD | power_out | I/O power supply, 1.1V to 3.6V. |
