AD623ARZ

Single and Dual-Supply, Rail-to-Rail,  Low Cost Instrumentation Amplifier

仪表放大器 SINGLE SUPPLY RR

GENERAL DESCRIPTION AD623ARZ

The AD623 is an integrated, single- or dual-supply instrumentation

amplifier that delivers rail-to-rail output swing using supply

voltages from 3 V to 12 V. The AD623 offers superior user

flexibility by allowing single gain set resistor programming and by

conforming to the 8-lead industry standard pinout configuration.

With no external resistor, the AD623 is configured for unity

gain (G = 1), and with an external resistor, the AD623 can be

programmed for gains of up to 1000.
