AD5171BRJZ10-R7

AD5171BRJZ10-R7 is a 64-position OTP digital potentiometer. It 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, and programmable filters up to 1.5MHz BW.

• Unlimited adjustments prior to OTP activation, end-to-end resistance is 10Kohm
• I²C-compatible digital interface, full read/write of wiper register, extra I²C device address pin
• Computer software replaces microcontroller in factory programming applications
• Voltage divider temperature coefficient is 5ppm/°C typical at (VDD = 3V to 5V ±10%)
• Resistance temperature coefficient is 35ppm/°C typical at (VDD = 3V to 5V ±10%)
• Adjustment settling time is 5μs typical at (VA = 5V ±1LSB error band, VB = 0V, measured at VW)
• Resistor noise voltage is 8nV/√Hz typical at (RAB = 5Kohm, f = 1KHz, code = 0x20)
• Power supply voltage range from 2.7V to 5.5V, power dissipation is 0.02mW typical
• 600KHz typical -3dB bandwidth at (RAB = 10Kohm, code = 0x20)
• Operating temperature range from -40°C to +125°C, 8-lead SOT-23 package
