WM8761CBGED

Cirrus Logic · Digital To Analog Converters (DACs) · SOIC-14

WM8761CBGED from Cirrus Logic, in a SOIC-14. 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 LRCIN input Sample rate (left/right) clock input with Schmitt trigger buffer; an LRCIN of 4 BCKINs or less duration selects DSP format.
2 DIN input Serial audio data input with Schmitt trigger buffer.
3 BCKIN input Bit clock input with Schmitt trigger buffer; minimum cycle time 40ns.
4 NC unconnected No internal connection.
5 CAP passive Analogue internal reference at VDD/2, to be decoupled with 10uF and 0.1uF capacitors.
6 VOUTR output Right channel DAC output, 1.1 Vrms at 0dBFS into 10k load with VDD = 5V.
7 GND power_in Negative supply (ground).
8 VDD power_in Positive supply, 2.7V to 5.5V.
9 VOUTL output Left channel DAC output, 1.1 Vrms at 0dBFS into 10k load with VDD = 5V.
10 MUTE bidirectional Soft mute control with internal pull down: high = mute on, low = mute off, high impedance = automute (pin indicates automuted state through 10k).
11 NC unconnected No internal connection.
12 DEEMPH input De-emphasis select with internal pull up: high = de-emphasis on, low = off.
13 FORMAT input Data input format select with internal pull up: low = 24-bit right justified or DSP 'late', high = 16-24-bit I2S or DSP 'early'.
14 MCLK input Master clock input, 128fs to 768fs, max 50MHz; stopping MCLK powers the device down.
