The AD2700 family provides precision 10 V references with very high accuracy, low temperature coefficient, and up to 10 mA output current. The series includes a positive reference (AD2700), a negative reference (AD2701), and a dual‑output version (AD2702) suitable for high‑resolution data converters and calibration systems. Devices are offered in multiple grades covering temperature ranges from –25 °C to +85 °C and up to +125 °C for S and U grades.
The handbook contains functional block diagrams, detailed specifications such as output voltage error, line and load regulation, noise, and long‑term stability, as well as package dimensions and pin assignments. Application examples show how to use the references with AD7520 DACs and operational amplifiers for unipolar and bipolar output configurations.
