AD5144BRUZ10-RL7

Analog Devices · Digital Potentiometers · TSSOP-20

AD5144BRUZ10-RL7 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	SYNC	input	Synchronization data input, active low; data is loaded into the input shift register when SYNC returns high.
2	GND	power_in	Ground pin serving as the logic ground reference.
3	A1	passive	Terminal A of RDAC1, with VSS ≤ VA ≤ VDD.
4	W1	passive	Wiper terminal of RDAC1, with VSS ≤ VW ≤ VDD.
5	B1	passive	Terminal B of RDAC1, with VSS ≤ VB ≤ VDD.
6	A3	passive	Terminal A of RDAC3, with VSS ≤ VA ≤ VDD.
7	W3	passive	Wiper terminal of RDAC3, with VSS ≤ VW ≤ VDD.
8	B3	passive	Terminal B of RDAC3, with VSS ≤ VB ≤ VDD.
9	VSS	power_in	Negative power supply; decouple with 0.1 µF ceramic and 10 µF capacitors.
10	A2	passive	Terminal A of RDAC2, with VSS ≤ VA ≤ VDD.
11	W2	passive	Wiper terminal of RDAC2, with VSS ≤ VW ≤ VDD.
12	B2	passive	Terminal B of RDAC2, with VSS ≤ VB ≤ VDD.
13	A4	passive	Terminal A of RDAC4, with VSS ≤ VA ≤ VDD.
14	W4	passive	Wiper terminal of RDAC4, with VSS ≤ VW ≤ VDD.
15	B4	passive	Terminal B of RDAC4, with VSS ≤ VB ≤ VDD.
16	VDD	power_in	Positive power supply; decouple with 0.1 µF ceramic and 10 µF capacitors.
17	VLOGIC	power_in	Logic power supply from 1.8 V to VDD; decouple with 0.1 µF ceramic and 10 µF capacitors.
18	SCLK	input	Serial clock line; data is clocked in at the logic low transition.
19	SDI	input	Serial data input.
20	SDO	output	Serial data output; open-drain output that needs an external pull-up resistor.
