DAC7725UB

Texas Instruments · Digital To Analog Converters (DAC) · SOIC-28-300mil

DAC7725UB from Texas Instruments, in a SOIC-28-300mil. 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 VREFH input Reference Input Voltage High; sets the maximum output voltage for all DACs.
2 VOUTB output DAC B Voltage Output.
3 VOUTA output DAC A Voltage Output.
4 VSS power_in Negative Analog Supply Voltage, either 0V (single supply) or -15V (dual supply).
5 GND power_in Ground.
6 RESET input Asynchronous Reset Input; when LOW it sets the DAC and input registers to mid-scale (800H, DAC7724) or zero-scale (000H, DAC7725).
7 LDAC input Load DAC Input; all DAC registers are transparent when LOW.
8 DB0 bidirectional Data Bit 0, least significant bit of the 12-bit word.
9 DB1 bidirectional Data Bit 1 of the 12-bit parallel data word.
10 DB2 bidirectional Data Bit 2 of the 12-bit parallel data word.
11 DB3 bidirectional Data Bit 3 of the 12-bit parallel data word.
12 DB4 bidirectional Data Bit 4 of the 12-bit parallel data word.
13 DB5 bidirectional Data Bit 5 of the 12-bit parallel data word.
14 DB6 bidirectional Data Bit 6 of the 12-bit parallel data word.
15 DB7 bidirectional Data Bit 7 of the 12-bit parallel data word.
16 DB8 bidirectional Data Bit 8 of the 12-bit parallel data word.
17 DB9 bidirectional Data Bit 9 of the 12-bit parallel data word.
18 DB10 bidirectional Data Bit 10 of the 12-bit parallel data word.
19 DB11 bidirectional Data Bit 11, most significant bit of the 12-bit word.
20 R/W input Read/Write Control Input; read when HIGH, write when LOW.
21 A1 input Register/DAC Select; C or D when HIGH, A or B when LOW.
22 A0 input Register/DAC Select; B or D when HIGH, A or C when LOW.
23 CS input Chip Select Input.
24 VDD power_in Positive Digital Supply, +5V (specified range 4.75V to 5.25V on page 2).
25 VCC power_in Positive Analog Supply Voltage, +15V nominal (specified range 14.25V to 15.75V on page 2).
26 VOUTD output DAC D Voltage Output.
27 VOUTC output DAC C Voltage Output.
28 VREFL input Reference Input Voltage Low; sets the minimum output voltage for all DACs.
