HT5320ARMZ

HTCSEMI · Digital To Analog Converters (DAC) · MSOP-8

HT5320ARMZ from HTCSEMI, in a MSOP-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 VDD power_in Power supply input, +2.7V to 5.5V; must be shorted to VDD2 (pin 2) on the MSOP-8.
2 VDD2 power_in Second power supply pin, +2.7V to 5.5V; the datasheet note says it must be shorted to VDD (pin 1).
3 NC unconnected No internal connection.
4 VOUT output Analog output voltage from the DAC; the output amplifier has rail-to-rail operation (0V to VDD).
5 SYNC input Active-LOW frame synchronization input; LOW enables the input shift register, the DAC updates after the 16th clock unless SYNC goes HIGH first, which interrupts and ignores the write.
6 SCLK input Serial clock input; data can be transferred at rates up to 30MHz.
7 DIN input Serial data input; data is clocked into the 16-bit input shift register on the falling edge of the serial clock.
8 GND power_in Ground reference point for all circuitry on the part.
