DAC61401PWR

Texas Instruments · IC · TSSOP-20

DAC61401PWR from Texas Instruments, in a TSSOP-20. 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 VREFIO bidirectional Internal reference output or external reference input; connect a 150nF capacitor to ground.
2 VREFGND input Reference ground, connects to 0V.
3 AVSS power_in Negative analog power supply, specified at -21.5V to 0V to GND in recommended operating conditions.
4 NC unconnected Must be left unconnected, pin floating.
5 AVDD power_in Positive analog power supply, specified at 4.5V to 41.5V to GND in recommended operating conditions.
6 NC unconnected Must be left unconnected, pin floating.
7 CCOMP input External compensation capacitor connection for VOUT; a 470pF typical capacitor improves stability with loads up to 1μF at the cost of increased settling time.
8 NC unconnected Must be left unconnected, pin floating.
9 VOUT output DAC voltage output pin.
10 VSENSEP input Sense pin for the positive voltage output load connection.
11 VSENSEN input Connect to 0V.
12 FAULT output Open-drain fault output that goes low when a fault condition is detected; requires an external 10kΩ pullup resistor.
13 SDO output Serial data output, with data valid on the rising or falling edge of SCLK as set by FSDO; high-impedance when SYNC is high.
14 SCLK input SPI serial clock input supporting rates up to 50MHz, with Schmitt-trigger logic input.
15 SDIN input Serial data input, clocked into the register on the falling edge of SCLK, with Schmitt-trigger logic input.
16 SYNC input Active-low SPI chip select; data is not clocked into the shift register unless SYNC is low.
17 IOVDD power_in IO pin power supply, specified at 1.7V to 5.5V to GND.
18 NC unconnected Must be left unconnected, pin floating.
19 GND power_in Digital and analog ground, connects to 0V.
20 VDD power_in Digital and analog power supply, specified at 4.5V to 5.5V to GND.
