MV / microvolt signal amplifier voltage amplifier AD623/AD620 instrumentation amplifier module

AD623 instrumentation amplifier module

The AD623 maintains superior performance with dual and single Parity power supplies.
The AD623 instrumentation amplifier module from Analog Devices 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. The superior accuracy of the AD623 is the result of increasing ac common-mode rejection ratio (CMRR) coincident with increasing gain; line noise harmonics are rejected due to constant CMRR up to 200 Hz. The AD623 has a wide input common-mode range and amplifies signals with common mode voltages as low as 150 mV below ground.

Applications of AD623 Instrumentation Amplifier Module:

• Low power medical instrumentation
• Transducer interfaces
• Thermocouple amplifiers
• Industrial process controls
• Difference amplifiers
• Low power data acquisition
