AD5247BKSZ10 Digital Potentiometer by Analog Devices Inc.

The AD5247BKSZ10 is a precision digital potentiometer designed and manufactured by Analog Devices Inc., a leader in high-performance analog, mixed-signal, and digital signal processing integrated circuits. This compact, digitally controlled variable resistor offers a seamless solution for adjusting and controlling voltage and current in a wide array of electronic applications.

Featuring a 10 kΩ end-to-end resistance with a 256-position, the AD5247BKSZ10 provides fine-grain control, allowing for precise adjustments to the resistance settings. It operates with a dual supply voltage ranging from ±2.7 V to ±5.5 V or a single supply voltage from 2.7 V to 5.5 V, catering to various system requirements and ensuring compatibility with both bipolar and single-ended applications.

One of the standout features of this digital potentiometer is its I²C-compatible interface, which permits easy communication with microcontrollers or microprocessors. This interface enables the user to read back the wiper register content, providing feedback on the current setting and facilitating adaptive adjustments in response to system changes or external stimuli.

The AD5247BKSZ10 boasts a compact form factor, being available in a small 6-lead SC70 package, which is critical for space-constrained applications. Its operational temperature range of -40°C to +125°C ensures reliability and performance across a broad spectrum of environmental conditions, making it suitable for industrial, automotive, and consumer electronics applications.

Additional features include nonvolatile memory (EEPROM), which allows the device to retain the last position of the potentiometer wiper upon power-down, ensuring a consistent start-up configuration. The robust design of the AD5247BKSZ10 also includes 50 ppm/°C end-to-end resistance temperature coefficient and 5 ppm/°C ratiometric temperature coefficient, providing stable performance over temperature variations.

Whether it's for calibrating system tolerances, controlling LCD screen brightness, or setting operational parameters in a closed-loop control system, the AD5247BKSZ10 from Analog Devices Inc. is an excellent choice for designers looking for a reliable and precise digital potentiometer.
