DAC70504RTER
Texas Instruments · Digital To Analog Converters (DAC) · WQFN-16-EP(3x3)
DAC70504RTER from Texas Instruments, in a WQFN-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 | REF | bidirectional | When using the internal reference this is the reference output voltage pin (default); when using an external reference it is the reference input pin to the device. |
| 2 | OUT0 | output | Analog output voltage from DAC 0. |
| 3 | OUT1 | output | Analog output voltage from DAC 1. |
| 4 | OUT2 | output | Analog output voltage from DAC 2. |
| 5 | OUT3 | output | Analog output voltage from DAC 3. |
| 6 | GND | power_in | Ground reference point for all circuitry on the device. |
| 7 | VDD | power_in | Analog supply voltage, 2.7 V to 5.5 V. |
| 8 | GAIN | input | Sets the initial buffer amplifier gain for all four channels at power-up or reset: tied to GND gives gain 1, tied to VIO gives gain 2; changing it after power-up does not affect operation. |
| 9 | RSTSEL | input | Reset select: when tied to GND all four DACs reset to zero scale, and when connected to VIO all four DACs reset to midscale. |
| 10 | REFDIV | input | Sets the reference divider at power-up or reset: tied to GND the reference is not divided, tied to VIO the reference is divided by 2; changing it after power-up does not affect operation. |
| 11 | LDAC | input | A high-to-low transition updates the DAC outputs of channels configured in synchronous mode simultaneously, and the pin can be tied permanently to GND. |
| 12 | CS | input | Active-low serial data enable and frame synchronization signal; when it goes low it enables the serial interface input shift register. |
| 13 | SCLK | input | Serial interface clock. |
| 14 | SDI | input | Serial interface data input, clocked into the input shift register on each falling edge of SCLK. |
| 15 | SDO/ALARM | output | Serial data output by default, high impedance when CS is high; alternatively configurable as an open-drain ALARM output for CRC or reference alarm events, which requires a 10 kΩ pull-up to VIO. |
| 16 | VIO | power_in | IO supply voltage, 1.7 V to 5.5 V, setting the I/O operating voltage for the serial interface. |
| 17 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
