AD5543BRMZ

Analog Devices · Digital To Analog Converters (DACs) · MSOP-8

AD5543BRMZ from Analog Devices, 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 CLK input Clock input that is positive-edge triggered and clocks data into the shift register, with a 50 MHz maximum clock input frequency and 10 ns minimum clock high and low widths.
2 SDI input Serial register input where data loads directly into the shift register MSB first, and extra leading bits are ignored.
3 RFB passive Internal matching feedback resistor (5 kΩ nominal) that connects to the external operational amplifier output for voltage output, and VDD must be powered for continuity when measuring it.
4 VREF power_in DAC reference input that establishes the full-scale voltage over a range of −15 V to +15 V (min/max) with constant input resistance versus code.
5 IOUT output DAC current output that connects to the inverting terminal of the external precision I-to-V operational amplifier, typically 2 mA full-scale for data 0xFFFF on the AD5543.
6 GND power_in Analog and digital ground reference for the device.
7 VDD power_in Positive power supply input specified for 5 V ±10% operation (4.5 V min to 5.5 V max), which also powers the internal logic that drives the DAC switches.
8 CS input Active-low chip select that transfers shift register data to the DAC register on its rising edge, and CLK must not toggle during this strobe.
