DAC7552IRGTR from Texas Instruments, in a TQFN-16-EP(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 voltage output from DAC A; the output swings rail-to-rail over 0 V to VREF. |
| 2 | VDD | power_in | Analog supply input, 2.7 V to 5.5 V. |
| 3 | GND | power_in | Ground; the thermal pad should be connected to GND. |
| 4 | VOUTB | output | Analog voltage output from DAC B; the output swings rail-to-rail over 0 V to VREF. |
| 5 | VFBB | input | DAC B amplifier sense input; for voltage output operation, connect to VOUTB externally. |
| 6 | VREFB | input | Positive reference voltage input for DAC B; input range 0 V to VDD. |
| 7 | PD | input | Power-down control input; the datasheet gives no polarity or threshold for this pin in the pin table. |
| 8 | DCEN | input | Daisy-chain enable input. |
| 9 | SDO | output | Serial data output for daisy-chaining; SDO is valid 10 ns max after the SCLK falling edge at VDD = 2.7 V to 3.6 V (t9). |
| 10 | IOVDD | power_in | I/O voltage supply input; for single-supply operation, connect to VDD externally. |
| 11 | SYNC | input | Frame synchronization input; the falling edge of SYNC indicates the start of a serial data frame shifted into the DAC7552. |
| 12 | SCLK | input | Serial clock input, up to 50 MHz. |
| 13 | SDIN | input | Serial data input. |
| 14 | CLR | input | Asynchronous clear input; when low, the DAC registers are set to 000H and the output voltage to 0 V. |
| 15 | VREFA | input | Positive reference voltage input for DAC A; input range 0 V to VDD. |
| 16 | VFBA | input | DAC A amplifier sense input; for voltage output operation, connect to VOUTA externally. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
