ADI AD5112BCPZ5-500R7

The AD5110/AD5112/AD5114 provide a nonvolatile solution for 128/64/32-position adjustment applications, with a guaranteed low resistance tolerance error of ±8%. The A, B, and W pins support a current density of up to ±6 mA. The low resistance tolerance, low nominal temperature coefficient, and high bandwidth characteristics simplify open-loop and tolerance-matching applications. The new low wiper resistance feature reduces the wiper resistance at both ends of the resistor array to 45 Ω (typical). The wiper position can be controlled via an I²C-compatible digital interface, which also supports readback of the wiper register and EEPROM contents. Resistance tolerance is stored in EEPROM, with end-to-end tolerance accuracy of 0.1%. The AD5110/AD5112/AD5114 are available in a 2 mm × 2 mm LFCSP package and are guaranteed over an extended industrial temperature range of −40°C to +125°C.
