High quality sales of AD5142ABRUZ100 Digital Potentiometer 100k Ohm 2 Circuit 256 Taps I²C Interface 16-TSSOP
Digital Potentiometer 100kOhm 256POS Non-Volatile Linear/Log 16-Pin TSSOP Tube
Product Descriptions
The AD5122A/AD5142A potentiometers provide a nonvolatile solution for 128-/256-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and up to ±6 mA current density in the Ax, Bx, and Wx pins.
The low resistor tolerance and low nominal temperature coefficient simplify open-loop applications as well as applications requiring
tolerance matching.
The linear gain setting mode allows independent programming of the resistance between the digital potentiometer terminals, through
RAW and RWB the string resistors, allowing very accurate resistor matching.
The high bandwidth and low total harmonic distortion (THD) ensure optimal performance for ac signals, making it suitable for filter
design.
The low wiper resistance of only 40 Ω at the ends of the resistor array allows for pin-to-pin connection.
The wiper values can be set through an I2C-compatible digital interface that is also used to read back the wiper register and
EEPROM contents.
The AD5122A/AD5142A are available in a compact, 16-lead, 3 mm× 3 mm LFCSP and a 16-lead TSSOP. The parts are guaranteed to operate over the extended industrial temperature range of −40°C to+125°C.
