Product Summary

The AD820A is a precision, low power FET input op amp that can operate from a single supply of +3.0 V to 36 V, or dual supplies of ±1.5 V to ±18 V. It has true single supply capability with an input voltage range extending below the negative rail, allowing the AD820A to accommodate input signals below ground in the single supply mode.

Parametrics

AD820A absolute maximum ratings: (1)Supply Voltage: ±18 V; (2)Internal Power Dissipation, Plastic DIP (N): 1.6 Watts, SOIC (R): 1.0 Watts; (3)Input Voltage: (+VS + 0.2 V) to – (20 V + VS); (4)Output Short Circuit Duration: Indefinite; (5)Differential Input Voltage: ±30 V; (6)Storage Temperature Range (N): –65℃ to +125℃; (7)Storage Temperature Range (R): –65℃ to +150℃; (8)Operating Temperature Range, AD820A/B: –40℃ to +85℃; (9)Lead Temperature Range(Soldering 60 sec): +260℃.
