Parametric profile for signal-chain design
The AD8224ACPZ-R7: Each of the two channels draws 750 µA supply current, keeping the total quiescent draw at 1.5 mA for the dual package. Rail-to-rail output swing allows the amplifier to drive the full supply range into an ADC input or a downstream stage without headroom loss. Input bias current is 25 pA typical, and input offset voltage is 300 µV — figures that suit bridge-type sensors and thermocouple amplifiers where DC accuracy matters. Output drive capability is 15 mA per channel, enough to drive a reference input or a moderate cable load. The supply span ranges from 4.5 V to 36 V, accommodating single 5 V rails up to ±18 V dual supplies.
Package, lifecycle and sourcing
