Analog Devices · Digital To Analog Converters (DACs) · TSSOP-20

AD5343BRUZ from Analog Devices, in a TSSOP-20. 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 HBEN input This pin is used when writing to the device to determine if data is written to the high byte register or the low byte register.
2 VREF power_in Unbuffered reference input for both DACs.
3 VOUTA output Output of DAC A, buffered with rail-to-rail operation.
4 VOUTB output Output of DAC B, buffered with rail-to-rail operation.
5 GND power_in Ground reference point for all circuitry on the part.
6 CS input Active low Chip Select Input, used in conjunction with WR to write data to the parallel interface.
7 WR input Active low Write Input, used in conjunction with CS to write data to the parallel interface.
8 A0 input Address pin for selecting between DAC A and DAC B.
9 CLR input Asynchronous active low control input that clears all input registers and DAC registers to zeros.
10 LDAC input Active low control input that updates the DAC registers with the contents of the input registers, allowing all DAC outputs to be simultaneously updated.
11 PD input Power-Down Pin: this active low control pin puts all DACs into power-down mode.
12 VDD power_in Power supply pin; the part operates from 2.5 V to 5.5 V and the supply should be decoupled with a 10 µF capacitor in parallel with a 0.1 µF capacitor to GND.
13 DB0 input Parallel data input, bit 0 of the eight parallel data inputs (DB7 is the MSB).
14 DB1 input Parallel data input, bit 1 of the eight parallel data inputs (DB7 is the MSB).
15 DB2 input Parallel data input, bit 2 of the eight parallel data inputs (DB7 is the MSB).
16 DB3 input Parallel data input, bit 3 of the eight parallel data inputs (DB7 is the MSB).
17 DB4 input Parallel data input, bit 4 of the eight parallel data inputs (DB7 is the MSB).
18 DB5 input Parallel data input, bit 5 of the eight parallel data inputs (DB7 is the MSB).
19 DB6 input Parallel data input, bit 6 of the eight parallel data inputs (DB7 is the MSB).
20 DB7 input Parallel data input, DB7 is the MSB of the eight parallel data inputs.
