AD5231BRUZ10

Analog Devices · Digital Potentiometers · TSSOP-16

AD5231BRUZ10 from Analog Devices, in a TSSOP-16. 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 O1 output Nonvolatile Digital Output 1 at ADDR = 0x1, data bit position D0; to store O1 high the data bit format is 0x310001.
2 CLK input Serial input register clock pin that shifts in one bit at a time on positive clock edges.
3 SDI input Serial data input pin that shifts in one bit at a time on positive CLK edges, MSB loaded first.
4 SDO output Serial data output pin for readback (Commands 9 and 10) and daisy-chain functions, delayed by 24 or 25 clock pulses, and it needs a 1 kΩ to 10 kΩ pull-up resistor.
5 GND power_in Ground pin, logic ground reference.
6 VSS power_in Negative supply, connected to 0 V for single-supply applications; in dual-supply use it must sink 40 mA for 25 ms when storing data to EEMEM.
7 T passive Reserved for factory testing; connect to VDD or VSS.
8 B passive Terminal B of RDAC.
9 W passive Wiper terminal of RDAC, ADDR (RDAC) = 0x0.
10 A passive Terminal A of RDAC.
11 VDD power_in Positive power supply pin.
12 WP input Optional active-low write protect pin that prevents changes to present contents except PR and Instructions 1 and 8; tie to VDD if not used.
13 PR input Optional hardware override preset pin that refreshes the scratchpad register with the EEMEM contents (factory default midscale 512), activated at the logic high transition; tie to VDD if not used.
14 CS input Serial register chip select, active low, with serial register operation taking place when CS returns to logic high.
15 RDY output Ready, active-high open-drain output that identifies completion of Instructions 2, 3, 8, 9, 10, and PR.
16 O2 output Nonvolatile Digital Output 2 at ADDR = 0x1, data bit position D1; to store O2 high the data bit format is 0x310002.
