AD5124BRUZ10 quad 128/256-position nonvolatile digital potentiometer
The AD5124/AD5144/AD5144A potentiometers provide a nonvolatile solution for 128/256-bit adjustment applications, guaranteeing low resistance tolerance errors of ±8%, and current densities of up to ±6mA on the Ax, Bx, and Wx pins.
Low resistance tolerance and low nominal temperature coefficient simplify open-loop applications and applications that require tolerance matching.
Linear gain setting mode allows for digital potentiometer terminal RAWand RWBThe resistors are programmed independently to make the resistor matching very precise.
The wide bandwidth and low total harmonic distortion (THD) ensure optimal performance for AC signals and are suitable for filter designs.
The low vernier resistance at the end of the resistor array is only 40 Ω, allowing pin-to-pin connections.
The wiper resistance value can be passed by one SPI/I2C is compatible with digital interface settings that can also be used to read back wiper registers and EEMEM content.
The AD5124/AD5144/AD5144A are available in a compact 24-lead, 4 mm × 4 mm LFCSP package and a 20-lead TSSOP package. The extended industrial temperature range of −40°C to +125°C is guaranteed to operate.
