MicroSIZE Packages

high input impedance and rail-to-rail output swing

within 18 mV of the rails. The input common-mode

range includes the negative rail. Either single or dual

supplies can be used in the range of +4.0 V to +36 V

(

±2 V to ±18 V).

The dual version is offered in MSOP-8 and SO-8

packages. The quad is offered in SO-14 and

TSSOP-14 packages. All versions are specified for

operation from

–40°C to +105°C.
