MS5620

Hangzhou Ruimeng Tech · Digital To Analog Converters (DAC) · SOP-14

MS5620 from Hangzhou Ruimeng Tech, in a SOP-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 GND power_in Reference ground potential for the device; the DAC output of 0 V (zero code) is referenced to this pin.
2 REFA input Reference voltage input for DAC channel A, which has high input impedance; the absolute input range is -0.3 V to VDD+0.3 V.
3 REFB input Reference voltage input for DAC channel B, which has high input impedance; the absolute input range is -0.3 V to VDD+0.3 V.
4 REFC input Reference voltage input for DAC channel C, which has high input impedance; the absolute input range is -0.3 V to VDD+0.3 V.
5 REFD input Reference voltage input for DAC channel D, which has high input impedance; the absolute input range is -0.3 V to VDD+0.3 V.
6 DATA input Serial interface digital data input; each bit is written into the serial register on the falling edge of CLK, with digital inputs limited to -0.3 V to VDD+0.3 V.
7 CLK input Serial interface clock; input data is written into the serial register on the falling edge of CLK, with a maximum clock frequency of 1 MHz.
8 LOAD input Serial interface data load; when LDAC is low, a falling edge on LOAD latches data into the output latch and immediately converts it on the selected DAC channel.
9 DACD output Analog voltage output of DAC channel D, buffered with a selectable gain of 1 or 2 times the reference voltage.
10 DACC output Analog voltage output of DAC channel C, buffered with a selectable gain of 1 or 2 times the reference voltage.
11 DACB output Analog voltage output of DAC channel B, buffered with a selectable gain of 1 or 2 times the reference voltage.
12 DACA output Analog voltage output of DAC channel A, buffered with a selectable gain of 1 or 2 times the reference voltage.
13 LDAC input DAC data load; when high, the DAC outputs are not updated while data is shifted in, and the outputs update only on a high-to-low transition of LDAC.
14 VDD power_in Power supply voltage; recommended operation is 2.7 V to 5.25 V, with an absolute maximum of 7 V.
