CJC4334H from ESHINE, in a SOP-8. 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 | SDIN | input | Serial Audio Data Input accepts two's complement serial audio data. |
| 2 | SCLK | input | Serial Clock provides the clock for the serial audio interface. |
| 3 | LRCK | input | Left/Right Clock determines which channel, left or right, is currently active on the serial audio data line. |
| 4 | MCLK | input | Master Clock is the clock source for the delta-sigma modulator and digital filters. |
| 5 | AOUTL | output | Analog left line output whose full-scale level is specified in the Analog Characteristics (2.7 to 2.9 VPP at 0 dBFS, 2.8 VPP typical). |
| 6 | GND | power_in | Ground reference for the device; all voltages are referenced to GND. |
| 7 | VDD | power_in | Positive analog power supply (3.0 V to 3.6 V, 3.3 V typical) that also feeds the regulator for the digital core logic. |
| 8 | AOUTR | output | Analog right line output whose full-scale level is specified in the Analog Characteristics (2.7 to 2.9 VPP at 0 dBFS, 2.8 VPP typical). |
