AD623ARZ Description
The AD623ARZ is a single- or dual-supply integrated instrumentation amplifier with rail-to-rail output swing and supply voltages ranging from 3 to 12 V. By permitting single gain set resistor programming and adhering to the industry-standard pinout design, the AD623ARZ provides improved user flexibility. The AD623ARZ is designed for unity gain (G = 1) without an external resistor and may be programmed for gains of up to 1000 with an external resistor. The AD623ARZ achieves improved accuracy by increasing the ac common-mode rejection ratio (CMRR) at the same time as increasing gain; line noise harmonics are rejected due to constant CMRR up to 200 Hz. The AD623ARZ amplifies signals with common-mode voltages as low as 150 mV below ground and has a wide input common-mode range. With dual and single polarity power supply, the AD623ARZ maintains exceptional performance.
