Texas Instruments · Audio Amplifiers · VQFN-32-EP(4x4)

TAS5722LRSMR from Texas Instruments, in a VQFN-32-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 VREF_N power_in Negative reference for the analog circuitry; connect to the negative pins of the VCOM and VREG decoupling capacitors.
2 FAULTZ output Open-drain active-low fault flag; pull up on the PCB with a resistor to DVDD.
3 SDZ input Active-low shutdown signal; assert low to hold the device inactive.
4 LRCLK input TDM interface left/right clock.
5 MCLK input Device master clock.
6 BCLK input TDM interface serial bit clock.
7 SDI input TDM interface data input.
8 SCL input I2C clock input; pull up on the PCB with a 2.4-kΩ resistor.
9 SDA bidirectional I2C bidirectional data; pull up on the PCB with a 2.4-kΩ resistor.
10 GND power_in Ground; connect to the PCB ground plane.
11 DVDD power_in Digital power supply; connect to a 1.8-V supply (1.65 V to 2 V recommended range) with external decoupling capacitor.
12 ADR1 input I2C address input; each pin detects a short to DVDD, a short to GND, a 22-kΩ connection to GND and a 22-kΩ connection to DVDD.
13 ADR0 input I2C address input; each pin detects a short to DVDD, a short to GND, a 22-kΩ connection to GND and a 22-kΩ connection to DVDD.
14 PVDD power_in Class-D amplifier power supply input; connect to the PVDD supply (4.5 V to 17 V) and decouple externally.
15 PVDD power_in Class-D amplifier power supply input; connect to the PVDD supply (4.5 V to 17 V) and decouple externally.
16 OUT_N output Class-D amplifier negative output.
17 OUT_N output Class-D amplifier negative output.
18 BST_N power_in Class-D amplifier negative bootstrap; connect a capacitor between BST_N and OUT_N.
19 PGND power_in Power ground; connect to the PCB ground plane.
20 PGND power_in Power ground; connect to the PCB ground plane.
21 PGND power_in Power ground; connect to the PCB ground plane.
22 PGND power_in Power ground; connect to the PCB ground plane.
23 BST_P power_in Class-D amplifier positive bootstrap; connect a capacitor between BST_P and OUT_P.
24 OUT_P output Class-D amplifier positive output.
25 OUT_P output Class-D amplifier positive output.
26 PVDD power_in Class-D amplifier power supply input; connect to the PVDD supply (4.5 V to 17 V) and decouple externally.
27 PVDD power_in Class-D amplifier power supply input; connect to the PVDD supply (4.5 V to 17 V) and decouple externally.
28 AVDD power_in Analog power supply input; connect directly to PVDD (4.5 V to 17 V).
29 GND power_in Ground; connect to the PCB ground plane.
30 GVDD output Class-D amplifier gate drive regulator output; connect the decoupling capacitor to the PCB ground plane.
31 VREG output Analog regulator output; connect the decoupling capacitor to the VREF_N pin.
32 VCOM output Common-mode reference output; connect the decoupling capacitor to the VREF_N pin.
33 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
