WM8523GEDT

Cirrus Logic · Digital To Analog Converters (DACs) · TSSOP-20

WM8523GEDT from Cirrus Logic, in a TSSOP-20. 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 LINEVOUTL output Left channel line output, a ground-referenced 2Vrms line driver output per the datasheet features.
2 CPVOUTN output Charge pump negative rail decoupling pin.
3 CPCB output Charge pump fly-back capacitor pin.
4 LINEGND power_in Charge pump ground, with the ground reference specified at 0 V.
5 CPCA output Charge pump fly-back capacitor pin.
6 LINEVDD power_in Charge pump supply; the analogue supply range for AVDD and LINEVDD is 2.97 V to 3.63 V (3.3 V typical), and the two must stay within 0.3 V of each other.
7 ZFLAG output Zero flag output, which in hardware mode is asserted high after 1024 zero-count samples or while the device is muted.
8 DACDAT input Digital audio interface serial data input.
9 LRCLK bidirectional Digital audio interface left/right clock.
10 BCLK bidirectional Digital audio interface bit clock.
11 MCLK input Master clock input.
12 SDOUT/DEEMPH bidirectional Multi-function pin: I2C address select bit 1 in I2C mode, serial control data output in SPI mode, and de-emphasis select in hardware mode (0 = no de-emphasis, 1 = de-emphasis).
13 SDA/AIFMODE0 bidirectional Multi-function pin with an internal pull-down: serial control data input in I2C/SPI modes, and AIFMODE0 audio format select in hardware mode.
14 SCLK/AIFMODE1 bidirectional Multi-function pin with an internal pull-down: serial control clock input in I2C/SPI modes, and AIFMODE1 audio format select in hardware mode.
15 CS/MUTE input Multi-function pin: I2C address select bit 0 in I2C mode, serial chip select in SPI mode, and mute control in hardware mode (0 = mute enabled, 1 = mute disabled).
16 CIFMODE input Tri-level control interface mode select: 0 selects I2C mode, 1 selects SPI mode, and Z (left open/floating) selects hardware mode.
17 AGND power_in Analogue ground; analogue grounds must always be within 0.3 V of each other.
18 VMID output Analogue midrail decoupling pin.
19 AVDD power_in Analogue supply, specified at 2.97 V to 3.63 V (3.3 V typical) and must stay within 0.3 V of LINEVDD.
20 LINEVOUTR output Right channel line output, a ground-referenced 2Vrms line driver output per the datasheet features.
