AD5780BCPZ from Analog Devices, in a LFCSP-24(4x5). 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 | VOUT | output | Analog output voltage of the DAC; the output range is VREFN to VREFP per the output characteristics specification. |
| 2 | VREFP | input | Positive reference voltage input; a voltage in the range of 5 V to VDD − 2.5 V can be connected to this pin. |
| 3 | VDD | power_in | Positive analog supply connection; a voltage in the range of 7.5 V to 16.5 V can be connected, and VDD must be decoupled to AGND. |
| 4 | RESET | input | Active-low reset that returns the AD5780 to its power-on status when asserted. |
| 5 | VDD | power_in | Positive analog supply connection; a voltage in the range of 7.5 V to 16.5 V can be connected, and VDD must be decoupled to AGND. |
| 6 | CLR | input | Active-low clear input that sets the DAC register to a user-defined value (see Table 12) and updates the DAC output, with the value depending on binary or twos-complement coding. |
| 7 | LDAC | input | Active-low load DAC logic input that updates the DAC register and analog output; it must not be left unconnected. |
| 8 | VCC | power_in | Digital supply voltage in the range of 2.7 V to 5.5 V, which should be decoupled to DGND. |
| 9 | IOVCC | power_in | Digital interface supply to which the digital threshold levels are referenced; voltage range is 1.71 V to 5.5 V. |
| 10 | DNC | unconnected | Do not connect to this pin. |
| 11 | SDO | output | Serial data output; data is clocked out on the rising edge of the serial clock input. |
| 12 | SDIN | input | Serial data input to the 24-bit input shift register; data is clocked in on the falling edge of the serial clock. |
| 13 | SCLK | input | Serial clock input that clocks data into the input shift register on its falling edge, with transfer rates of up to 35 MHz. |
| 14 | SYNC | input | Active-low level-triggered frame synchronization input that enables the input shift register; the DAC is updated on its rising edge. |
| 15 | DGND | power_in | Ground reference pin for digital circuitry. |
| 16 | VREFN | input | Negative reference voltage input; the range is VSS + 2.5 V to 0 V per the general description. |
| 17 | VSS | power_in | Negative analog supply connection; a voltage in the range of −16.5 V to −2.5 V can be connected, and VSS must be decoupled to AGND. |
| 18 | VSS | power_in | Negative analog supply connection; a voltage in the range of −16.5 V to −2.5 V can be connected, and VSS must be decoupled to AGND. |
| 19 | AGND | power_in | Ground reference pin for analog circuitry. |
| 20 | RFB | passive | Feedback connection for an external amplifier; see the AD5780 Features section for further details. |
| 21 | DNC | unconnected | Do not connect to this pin. |
| 22 | DNC | unconnected | Do not connect to this pin. |
| 23 | DNC | unconnected | Do not connect to this pin. |
| 24 | INV | input | Inverting input connection for an external amplifier; see the AD5780 Features section for further details. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
