AD5144ABRUZ10 Four-channel 128/256-bit non-volatile digital potentiometer
The AD5124/AD5144/AD5144A potentiometers provide a non-volatile solution for 128/256-bit tuning applications, guaranteeing a low resistance tolerance of ± 8% and a current density 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.
The linear gain setting mode allows for independent programming of the resistance between the digital potentiometer terminals RAW and RWB, making resistance 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.
Vernier resistor values can be set via an SPI/I2C compatible digital interface, which can also be used to read back vernier registers and EEMEM content.
The AD5124/AD5144/AD5144A are available in compact 24-pin, 4 mm × 4 mm LFCSP packages, and 20-pin TSSOP packages. Guaranteed operating temperature range of −40°C to +125°C extended industrial temperature range.
