AD5171BRJZ5-R7

AD5171BRJZ5-R7 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. The AD5171 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, gains control and offset adjustments, transducer circuit adjustments, and programmable filters upto 1.5MHz BW.

• One-time programmable (OTP) set-and-forget resistance setting low cost alternative over EEMEM
• 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
• Voltage divider temperature coefficient is 5ppm/°C typical at (code = 0x20, VDD = 3V to 5V ±10%)
• Resistance temperature coefficient is 35ppm/°C typical at (VDD = 3V to 5V ±10%, VA = VDD, VB = 0V)
• 1500KHz typical -3dB bandwidth at (RAB = 5Kohm, code = 0x20)
• Adjustment settling time is 5μs typical at (VA = 5V ±1LSB error band, VB = 0V, measured at VW)
• Operating temperature range from -40°C to +125°C, 8-lead SOT-23
