DAC7625UB

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

DAC7625UB 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 that sets the maximum output voltage for all DACs, and must be at least 1.25V greater than VREFL.
2 VOUTB output DAC B voltage output, specified for output current of ±1.25mA and load capacitance up to 100pF without oscillation.
3 VOUTA output DAC A voltage output, specified for output current of ±1.25mA and load capacitance up to 100pF without oscillation.
4 VSS power_in Negative analog supply voltage of 0V or -5V; if not 0V it must be within -4.75V to -5.25V.
5 GND power_in Ground reference pin.
6 RESET input Asynchronous reset input that sets the DAC and input registers to mid-scale (800H) on the DAC7624 or zero-scale (000H) on the DAC7625 when LOW.
7 LDAC input Load DAC input; all DAC registers are transparent when LOW.
8 DB0 bidirectional Data bit 0, the least significant bit of the 12-bit word; bus is also driven for readback.
9 DB1 bidirectional Data bit 1 of the 12-bit parallel word; bus is also driven for readback.
10 DB2 bidirectional Data bit 2 of the 12-bit parallel word; bus is also driven for readback.
11 DB3 bidirectional Data bit 3 of the 12-bit parallel word; bus is also driven for readback.
12 DB4 bidirectional Data bit 4 of the 12-bit parallel word; bus is also driven for readback.
13 DB5 bidirectional Data bit 5 of the 12-bit parallel word; bus is also driven for readback.
14 DB6 bidirectional Data bit 6 of the 12-bit parallel word; bus is also driven for readback.
15 DB7 bidirectional Data bit 7 of the 12-bit parallel word; bus is also driven for readback.
16 DB8 bidirectional Data bit 8 of the 12-bit parallel word; bus is also driven for readback.
17 DB9 bidirectional Data bit 9 of the 12-bit parallel word; bus is also driven for readback.
18 DB10 bidirectional Data bit 10 of the 12-bit parallel word; bus is also driven for readback.
19 DB11 bidirectional Data bit 11, the most significant bit of the 12-bit word; bus is also driven for readback.
20 R/W input Read/write control input: read when HIGH, write when LOW.
21 A1 input Register/DAC select input: C or D when HIGH, A or B when LOW.
22 A0 input Register/DAC select input: B or D when HIGH, A or C when LOW.
23 CS input Chip select input.
24 NIC unconnected Not internally connected; the pin has no internal connection to the device.
25 VDD power_in Positive analog supply voltage, +5V nominal, specified from 4.75V to 5.25V.
26 VOUTD output DAC D voltage output, specified for output current of ±1.25mA and load capacitance up to 100pF without oscillation.
27 VOUTC output DAC C voltage output, specified for output current of ±1.25mA and load capacitance up to 100pF without oscillation.
28 VREFL input Reference input voltage low that sets the minimum output voltage for all DACs.
