TPA2014D1RGPR

Texas Instruments · Audio Power OpAmps · QFN-20-EP(4x4)

TPA2014D1RGPR from Texas Instruments, in a QFN-20-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 VDD power_in Supply voltage for the device, with a recommended operating range of 2.5 V to 5.5 V.
2 VCCFB input Voltage feedback input for the boost converter, with input voltage limited to -0.3 V to VDD + 0.3 V.
3 GAIN input Gain selection pin that sets the amplifier gain to 2 V/V, 6 V/V or 10 V/V.
4 AGND power_in Analog ground that must be connected together with all GND pins.
5 SDd input Shutdown terminal for the Class-D amplifier, with a high-level input threshold of 1.3 V minimum and a low-level threshold of 0.35 V maximum.
6 SDb input Shutdown terminal for the boost converter, with a high-level input threshold of 1.3 V minimum and a low-level threshold of 0.35 V maximum.
7 IN- input Negative audio input for the differential Class-D amplifier input.
8 IN+ input Positive audio input for the differential Class-D amplifier input.
9 PGND power_in Power ground that must be connected together with all GND pins.
10 PGND power_in Power ground that must be connected together with all GND pins.
11 VOUT- output Negative Class-D audio output, protected against shorts to ground, supply and output-to-output.
12 VOUT- output Negative Class-D audio output, protected against shorts to ground, supply and output-to-output.
13 VOUT+ output Positive Class-D audio output, protected against shorts to ground, supply and output-to-output.
14 VOUT+ output Positive Class-D audio output, protected against shorts to ground, supply and output-to-output.
15 VOUT+ output Positive Class-D audio output, protected against shorts to ground, supply and output-to-output.
16 VCCIN power_in Class-D audio power amplifier voltage supply that must be connected to VCCOUT.
17 VCCOUT power_out Boost converter output that must be connected to VCCIN.
18 SW passive Boost and rectifying switch input node.
19 SW passive Boost and rectifying switch input node.
20 PGND power_in Power ground that must be connected together with all GND pins.
21 Thermal Pad passive Exposed pad (from the footprint; not named in the datasheet pin table).
