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

AD5553CRMZ-REEL7 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. |
| 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 an external operational amplifier for voltage output. |
| 4 | VREF | power_in | DAC reference input that establishes the full-scale voltage with constant input resistance versus code, specified for VREF in the range −15 V to +15 V. |
| 5 | IOUT | output | DAC current output that connects to the inverting terminal of an external precision I-to-V operational amplifier. |
| 6 | GND | power_in | Analog and digital ground. |
| 7 | VDD | power_in | Positive power supply input specified for operation at 5 V ± 10% (4.5 V to 5.5 V). |
| 8 | CS | input | Active-low chip select that transfers shift register data to the DAC register on its rising edge. |
