AD5171BRJZ100-R7

AD5171 is a 64-position, one-time programmable (OTP) digital potentiometer that uses fuse link technology to achieve the memory retention of the resistance setting function. OTP is a cost-effective alternative over the EEMEM approach for users who do not need to reprogram new memory settings in the digital potentiometer. This device performs the same electronic adjustment function as most mechanical trimmers and variable resistors. It is programmed using a 2-wire, I²C®- compatible digital control. It allows unlimited adjustments before permanently setting the resistance value. It is used in applications such as system calibrations, electronics level settings, mechanical trimmers and potentiometer replacements, automotive electronics adjustments, gain control and offset adjustments, transducer circuit adjustments, programmable filters upto 1.5MHz BW.

• Unlimited adjustments prior to OTP activation
• I²C-compatible digital interface
• Computer software replaces microcontroller in factory programming applications
• Full read/write of wiper register, extra I²C device address pin
• Low operating voltage range from 2.7V to 5.5V, OTP validation check function
• Resistance temperature coefficient is 35ppm/°C typical at (VDD = 3V to 5V ± 10%)
• End-to-end resistance is 100Kohm
• Supply current is 4μA typical at (VIH = 5V or VIL = 0V)
• Fast settling time is 5μs typical in power-up
• Operating temperature is -40°C to +125°C, package style is 8-lead SOT-23
