PGA2320IDWR

Texas Instruments · Audio Amplifiers · SOIC-16-300mil

PGA2320IDWR from Texas Instruments, in a SOIC-16-300mil. 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 ZCEN input Zero Crossing Enable input (active high): zero crossing detection is disabled when ZCEN is low and enabled when it is high.
2 CS input Chip-select input (active low): data may be written to the PGA2320 only when CS is low.
3 SDI input Serial data input: a 16-bit control word (8 bits each for left and right gain, MSB first) is latched on the rising edge of SCLK.
4 VD+ power_in Digital power supply, +5V.
5 DGND power_in Digital ground.
6 SCLK input Serial clock input: SDI is latched on the rising edge of SCLK and SDO transitions on the falling edge.
7 SDO tri_state Serial data output used for daisy-chaining; it is a tristate output that assumes a high-impedance state when CS is high.
8 MUTE input Mute control input, active low: when low, each channel is muted following the next zero crossing or timeout on that channel.
9 VINR input Analog input, right channel, unbalanced and referenced to AGNDR; a source impedance above 600 Ω degrades distortion performance.
10 AGNDR power_in Analog ground, right channel.
11 VOUTR output Analog output, right channel.
12 VA+ power_in Analog power supply, +15V.
13 VA− power_in Analog power supply, −15V.
14 VOUTL output Analog output, left channel.
15 AGNDL power_in Analog ground, left channel.
16 VINL input Analog input, left channel, unbalanced and referenced to AGNDL; a source impedance above 600 Ω degrades distortion performance.
