AD5621BKSZ-500RL7

Analog Devices · Digital To Analog Converters (DAC) · SC-70-6(SOT-363)

AD5621BKSZ-500RL7 from Analog Devices, in a SC-70-6(SOT-363). 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 SYNC input Level-triggered active-low frame synchronization input; when SYNC goes low the input shift register is enabled, and if SYNC is taken high before the 16th clock edge its rising edge interrupts the write and the DAC ignores it.
2 SCLK input Serial clock input whose falling edge clocks data into the input shift register, with data transfer rates up to 30 MHz.
3 SDIN input Serial data input to a 16-bit shift register, with data clocked in on the falling edge of the serial clock.
4 VDD power_in Power supply input that can be operated from 2.7 V to 5.5 V and should be decoupled to GND.
5 GND power_in Ground reference point for all circuitry on the device.
6 VOUT output Analog buffered DAC output voltage from an output amplifier with rail-to-rail operation.
