These miniature, high-precision, lowquiescent-current op amps offer high input impedance and rail-to-rail output swing within 18 mV of the rails. The input common-mode range includes the negative rail. Single- or dual-supplies ranging from 4 V to 36 V (±2 V to ±18 V) can be used. The dual-channel version is offered in VSSOP-8 packages and SOIC-8 packages. The quad-chan...
