DAC7678SPWR

Texas Instruments · Digital To Analog Converters (DAC) · TSSOP-16

DAC7678SPWR from Texas Instruments, in a TSSOP-16. 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 LDAC input Load DACs pin for synchronous/asynchronous update of DAC output registers using falling edge trigger; active-low control input.
2 ADDR0 input Three-state address input 0 for I2C slave address selection; connect to AVDD, GND, or leave floating.
3 AVDD power_in Power-supply input with operating range 2.7V to 5.5V for analog and digital circuits.
4 VOUTA output Analog output voltage from DAC channel A with rail-to-rail output range 0V to AVDD.
5 VOUTC output Analog output voltage from DAC channel C with rail-to-rail output range 0V to AVDD.
6 VOUTE output Analog output voltage from DAC channel E with rail-to-rail output range 0V to AVDD.
7 VOUTG output Analog output voltage from DAC channel G with rail-to-rail output range 0V to AVDD.
8 VREFIN/VREFOUT bidirectional Positive reference input (0V to AVDD) for external reference mode, or 2.5V internal reference output (±5mV initial accuracy) when internal reference enabled; requires 100nF bypass capacitor.
9 CLR input Asynchronous clear input (active low, falling edge triggered) to reset all DAC registers and buffers to programmed clear code value.
10 VOUTH output Analog output voltage from DAC channel H with rail-to-rail output range 0V to AVDD.
11 VOUTF output Analog output voltage from DAC channel F with rail-to-rail output range 0V to AVDD.
12 VOUTD output Analog output voltage from DAC channel D with rail-to-rail output range 0V to AVDD.
13 VOUTB output Analog output voltage from DAC channel B with rail-to-rail output range 0V to AVDD.
14 GND power_in Ground reference point and return path for all analog and digital circuitry on the device.
15 SDA bidirectional Serial data input/output for I2C-compatible 2-wire interface; open-drain bidirectional line requiring external pull-up resistor (1kΩ to 10kΩ typical) to AVDD.
16 SCL input Serial clock input for I2C-compatible 2-wire interface supporting data rates up to 3.4MHz; Schmitt-trigger logic input.
