DAC7614U

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

DAC7614U from Texas Instruments, in a SOIC-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 VDD power_in Positive analog supply voltage, +5V nominal.
2 VOUTD output DAC D voltage output.
3 VOUTC output DAC C voltage output.
4 VREFL input Reference input voltage low, which sets the minimum output voltage for all DACs; VREFH must be at least 1.25V greater than VREFL.
5 VREFH input Reference input voltage high, which sets the maximum output voltage for all DACs.
6 VOUTB output DAC B voltage output.
7 VOUTA output DAC A voltage output.
8 VSS power_in Negative analog supply voltage, 0V or -5V nominal; it must be grounded or within -4.75V to -5.25V.
9 GND power_in Ground; all digital and analog return currents must flow through this pin.
10 SDI input Serial data input for the 16-bit serial word (2-bit DAC address plus 12-bit code, MSB first).
11 CLK input Serial data clock; it is OR-ed with CS to clock the serial shift register.
12 CS input Chip select input that enables serial communication when multiple serial devices share the bus.
13 NIC unconnected Not internally connected.
14 LOADDACS input The selected DAC register becomes transparent when LOADDACS is LOW and is latched when LOADDACS is HIGH.
15 RESET input Asynchronous reset input that sets all DAC registers to zero-scale (000H) or mid-scale (800H) when LOW, as selected by RESETSEL.
16 RESETSEL input Selects the reset code: when LOW, RESET sets all registers to 000H; when HIGH, RESET sets all registers to 800H.

CAD (KiCad official)

  • Symbol: DAC7614U
  • Footprint: Package_SO:SOIC-16_3.9x9.9mm_P1.27mm
  • 3D model: SOIC-16 (KiCad packages3D, STEP)
  • 3D model files: dac7614u-etched.step / dac7614u-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dac7614u.step / dac7614u.glb are the bare package body.
