DAC70504RTET

Texas Instruments · Digital To Analog Converters (DAC) · WQFN-16-EP(3x3)

DAC70504RTET 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), and 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 gain at power-up or reset: tied to GND gives gain 1 and tied to VIO gives gain 2, and changing it after power-up does not affect operation.
9 RSTSEL input Reset select: tied to GND resets all four DACs to zero scale, and connected to VIO resets all four DACs to midscale.
10 REFDIV input Sets the reference divider at power-up or reset: tied to GND the reference is not divided, and tied to VIO the reference is divided by 2, with later changes having no effect.
11 LDAC input A high-to-low transition updates the DAC outputs of channels in synchronous mode simultaneously, and the pin can be tied permanently to GND.
12 CS input Active-low serial data enable that serves as the frame synchronization signal; when low it enables the serial interface input shift register.
13 SCLK input Serial interface clock input.
14 SDI input Serial interface data input, clocked into the input shift register on each falling edge of SCLK.
15 SDO/ALARM tri_state Serial data output (default) that is high impedance when CS is high; it can instead be configured 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, which sets 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).

CAD (KiCad official)

  • Symbol: DAC70504RTET
  • Footprint: Package_DFN_QFN:QFN-16-1EP_3x3mm_P0.5mm_EP1.7x1.7mm
  • 3D model: WQFN-16-EP(3x3) (KiCad packages3D, STEP)
  • 3D model files: dac70504rtet-etched.step / dac70504rtet-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dac70504rtet.step / dac70504rtet.glb are the bare package body.
