Pinout

Pin Name Type Function
1 VREFP input Positive DAC reference input that defines the full-scale output voltage, with an allowable range of AVDD − 2.5 V to VREFN + 2.5 V.
2 VOUTB output Buffered analog output voltage of DAC B.
3 VOUTA output Buffered analog output voltage of DAC A.
4 AVSS power_in Negative analog supply pin, with voltage ranging from 0 V to −15 V.
5 DGND power_in Digital ground pin.
6 CLR input Active-low input that sets the input and DAC registers to zero scale (0x000) for the AD5725-1 or midscale (0x800) for the AD5725.
7 LDAC input Active-low load DAC input; taking it low while CS is high updates all output registers simultaneously, with a minimum pulse width of 10 ns.
8 DB0 bidirectional Data bit 0 (LSB) of the 12-bit parallel data bus used for writing and reading back data.
9 DB1 bidirectional Data bit 1 of the 12-bit parallel data bus used for writing and reading back data.
10 DB2 bidirectional Data bit 2 of the 12-bit parallel data bus used for writing and reading back data.
11 DB3 bidirectional Data bit 3 of the 12-bit parallel data bus used for writing and reading back data.
12 DB4 bidirectional Data bit 4 of the 12-bit parallel data bus used for writing and reading back data.
13 DB5 bidirectional Data bit 5 of the 12-bit parallel data bus used for writing and reading back data.
14 DB6 bidirectional Data bit 6 of the 12-bit parallel data bus used for writing and reading back data.
15 DB7 bidirectional Data bit 7 of the 12-bit parallel data bus used for writing and reading back data.
16 DB8 bidirectional Data bit 8 of the 12-bit parallel data bus used for writing and reading back data.
17 DB9 bidirectional Data bit 9 of the 12-bit parallel data bus used for writing and reading back data.
18 DB10 bidirectional Data bit 10 of the 12-bit parallel data bus used for writing and reading back data.
19 DB11 bidirectional Data bit 11 (MSB) of the 12-bit parallel data bus used for writing and reading back data.
20 R/W input Read/write pin that is active low to write data to the DAC and active high to read back data on the data bit pins when VL is connected to +5 V.
21 A1 input Address bit 1, which together with A0 selects DAC register A (00) through D (11).
22 A0 input Address bit 0, which together with A1 selects DAC register A (00) through D (11).
23 CS input Active-low chip select pin that enables decoding of the write and read operations.
24 VL power_in Voltage supply for the readback function that sets the digital output level, normally connected to +5 V; it can be left open-circuit if readback is not used.
25 AVDD power_in Positive analog supply pin, with voltage ranging from +5 V to +15 V.
26 VOUTD output Buffered analog output voltage of DAC D.
27 VOUTC output Buffered analog output voltage of DAC C.
28 VREFN input Negative DAC reference input that defines the zero-scale output voltage, with an allowable range of AVSS to VREFP − 2.5 V.
