GC4344 from SX-globalchip, in a MSOP-10. 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; digital input voltage must stay between -0.3 V and VA+0.4 V, with VA recommended at 3 V to 5.5 V. |
| 2 | DEM /SCLK | input | External serial clock input port; holding it low for five consecutive LRCK falling edges starts the de-emphasis filter, which is only valid in internal serial clock mode. |
| 3 | LRCK | input | Left/right clock port that determines the channel of the current input data, with a frequency equal to the input sample rate Fs and synchronized with SCLK. |
| 4 | MCLK | input | Primary master clock port, where the MCLK/LRCK ratio must be an integer and MCLK is specified at 0.512 MHz to 50 MHz with a 45% to 55% duty cycle. |
| 5 | VQ | passive | Filter connection for the internal quiescent voltage, which is specified as 0.5•VA VDC. |
| 6 | FILT+ | passive | Positive reference voltage for the internal sampling circuits. |
| 7 | AOUTL | output | Analog left channel output with a full-scale output of 0.60•VA to 0.70•VA Vpp, a maximum DC current of 10 uA, and a maximum load capacitance of 100 pF. |
| 8 | GND | power_in | Ground. |
| 9 | VA | power_in | Analog power supply with an absolute maximum of 6.0 V and a recommended range of 3 V to 5.5 V. |
| 10 | AOUTR | output | Analog right channel output with a full-scale output of 0.60•VA to 0.70•VA Vpp, a maximum DC current of 10 uA, and a maximum load capacitance of 100 pF. |
