ES9023P

ESS Tech · Digital To Analog Converters (DAC) · SOP-16

ES9023P from ESS Tech, in a SOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BCK input I2S Bit Clock input, typically 64x FS for serial data synchronization
2 LRCK input I2S L/R (Word) Clock for channel selection between left and right
3 SDI input I2S Serial Data Input for 24-bit PCM audio data
4 DIF input Mode select input, low for I2S mode or high for Left Justified mode
5 AVCC power_in Analog power supply, +3.6V ±5% (31mA nominal) or +3.3V ±5% (23mA nominal)
6 VREG power_out Analog Reference Output voltage for internal biasing and stabilization
7 AOUTL output Left channel audio output, ground-referenced up to 2Vrms into 5kΩ minimum load
8 AOUTR output Right channel audio output, ground-referenced up to 2Vrms into 5kΩ minimum load
9 CP passive Positive terminal of external 2.2µF charge pump capacitor
10 CN passive Negative terminal of external 2.2µF charge pump capacitor
11 NEG power_in Negative power supply voltage generated internally by charge pump
12 AGND power_in Analog ground reference for audio output stage and bias circuits
13 MCLK input Master Clock input, minimum 192x FS in asynchronous mode
14 DGND power_in Digital ground reference for digital input interface circuits
15 MUTE_B input Active-low mute control input with internal ramp timing and power management
16 ZD output Zero Detect status output, asserted high when both channels are zero for 8192 LRCK cycles
