AD5317RBCPZ-RL7 from Analog Devices, in a LFCSP-16(3x3). 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 | VOUTA | output | Analog output voltage from DAC A with rail-to-rail output amplifier. |
| 2 | GND | power_in | Ground reference point for all circuitry on the part. |
| 3 | VDD | power_in | Power supply input, 2.7 V to 5.5 V, decoupled with a 10 µF capacitor in parallel with a 0.1 µF capacitor to GND. |
| 4 | VOUTC | output | Analog output voltage from DAC C with rail-to-rail output amplifier. |
| 5 | VOUTD | output | Analog output voltage from DAC D with rail-to-rail output amplifier. |
| 6 | SDO | output | Serial data output for daisy-chaining or readback; data transfers on the rising edge of SCLK and is valid on the falling edge of the clock. |
| 7 | LDAC | input | Load DAC input operated asynchronously or synchronously; pulsing low updates DAC registers with new input register data, and it can be tied permanently low. |
| 8 | GAIN | input | Span set pin: tied to GND gives 0 V to VREF output span, tied to VLOGIC gives 0 V to 2 × VREF for all four DACs. |
| 9 | VLOGIC | power_in | Digital power supply, voltage range 1.62 V to 5.5 V. |
| 10 | SCLK | input | Serial clock input; data is clocked into the input shift register on the falling edge at rates up to 50 MHz. |
| 11 | SYNC | input | Active-low frame synchronization input; when low, data is transferred in on the falling edges of the next 24 clocks. |
| 12 | SDIN | input | Serial data input to the 24-bit input shift register, clocked in on the falling edge of the serial clock. |
| 13 | RESET | input | Asynchronous falling-edge-sensitive reset input that loads zero scale or midscale per RSTSEL and ignores LDAC pulses while low; tie to VLOGIC if unused. |
| 14 | RSTSEL | input | Power-on reset select: tied to GND powers up all four DACs to zero scale, tied to VLOGIC powers up to midscale. |
| 15 | VREF | power_in | Common reference pin: reference output when using the internal reference (default), reference input when using an external reference. |
| 16 | VOUTB | output | Analog output voltage from DAC B with rail-to-rail output amplifier. |
| 17 | EPAD | passive | Exposed pad; must be tied to GND. |
