The 1024-tap resolution provides 10-bit control (0-1023), giving step size of 100kOhm\/1024 = 97.6 Ohms per step. The resistor string consists of 1023 equal segments connected in series between terminals A and B. The wiper (W) connects to one of 1024 nodes via CMOS switches controlled by the 10-bit wiper register. Resistance between W and B is RWB = D x RAB\/1024, where D is the wiper code (0-1023). The SPI interface operates at up to 30MHz, with a 24-bit command word: 2 don't care bits + 2 command bits + 10 address bits + 10 data bits. The RDY output goes LOW during wiper transitions (typically 20us), allowing the MCU to wait until the wiper has settled before taking ADC measurements. The wiper contact resistance is typically 75 Ohms, which is a small fraction of the 100kOhm total resistance. The Y suffix denotes 20-time programmable (OTP) wiper memory: the current wiper position can be permanently stored in one-time-programmable memory up to 20 times, allowing the device to power-up at a preset position. The AD5290 is one of the few digital potentiometers with 1024-tap resolution, providing 4x finer adjustment than standard 256-tap devices.","pin_description":"
