Product Summary

The AD620BQ is a low cost, high accuracy instrumentation amplifier that requires only one external resistor to set gains of 1 to 1000. Furthermore, the AD620BQ features 8-lead SOIC and DIP packaging that is smaller than discrete designs, and offers lower power (only 1.3 mA max supply current), making it a good fit for battery powered, portable (or remote) applications.

Parametrics

AD620BQ absolute maximum rating: (1)Supply Voltage: ±18 V; (2)Internal Power Dissipation: 650 mW; (3)Input Voltage (Common Mode): ±VS; (4)Differential Input Voltage:±25 V; (5)Output Short Circuit Duration: Indefinite; (6)Storage Temperature Range (Q): –65 to +150℃; (7)Storage Temperature Range (N, R): –65 to +125℃; (8)Operating Temperature Range: –40 to +85℃; (9)Lead Temperature Range (Soldering 10 seconds): +300℃.
