AD623: Single Supply, Rail-Rail, Low Cost Instrumentation Amplifier
Product Description
The AD623 is an integrated single supply instrumentation amplifier that delivers rail-to-rail output swing. The AD623 offers superior user flexibility by allowing single gain set resistor programming, and 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 up to 1,000.
