DAC7632VFBT

Texas Instruments · Digital To Analog Converters (DAC) · LQFP-32(7x7)

DAC7632VFBT from Texas Instruments, in a LQFP-32(7x7). 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 VCC power_in Analog +5V power supply, specified at +4.75V to +5.25V.
2 AGND power_in Analog ground.
3 AGND power_in Analog ground.
4 NC unconnected No connection.
5 DGND power_in Digital ground.
6 DGND power_in Digital ground.
7 VDD power_in Digital +5V power supply, specified at +4.75V to +5.25V.
8 SDO output Serial data output, provided for daisy-chaining multiple devices.
9 NC unconnected No connection.
10 NC unconnected No connection.
11 NC unconnected No connection.
12 NC unconnected No connection.
13 NC unconnected No connection.
14 NC unconnected No connection.
15 NC unconnected No connection.
16 NC unconnected No connection.
17 CLK input Data clock input for the serial interface.
18 SDI input Serial data input; the device accepts 24-bit serial input data.
19 CS input Chip select, active LOW.
20 RSTSEL input Reset select: when HIGH, a RST command sets the DAC registers to mid-scale code 8000H; when LOW, it sets them to zero-scale code 0000H.
21 RST input Reset, rising-edge triggered; sets the DAC registers to mid-scale or zero-scale depending on RSTSEL.
22 LDAC input DAC register load control, rising-edge triggered.
23 LOAD input DAC input register load control, active LOW.
24 VSS power_in Analog -5V power supply (or 0V for single-supply operation), specified at -5.25V to -4.75V in dual-supply mode.
25 VOUTB output DAC B output voltage.
26 VOUTB Sense input DAC B output amplifier inverting input, used to close the feedback loop at the load.
27 VREFH Sense input DAC A and B reference high sense input.
28 VREFH input DAC A and B reference high input; reference high range is VREFL + 1.25V to +2.5V.
29 VREFL input DAC A and B reference low input; reference low range is -2.5V to VREFH - 1.25V.
30 VREFL Sense input DAC A and B reference low sense input.
31 VOUTA Sense input DAC A output amplifier inverting input, used to close the feedback loop at the load.
32 VOUTA output DAC A output voltage.
