NANOPOWER OPERATIONAL

AMPLIFIERS AND PUSH-PULL

COMPARATORS



DESCRIPTION

The UTC ULV2702 includes sub-micropower operational

amplifier and comparator into a single package that produces

excellent micropower signal conditioning with only 1.4µA of

supply current. This gives the designer more board space and

reduces part counts in systems that require an operational

amplifier and comparator. The low supply current makes it an

ideal choice for battery powered portable applications where

quiescent current is the primary concern. Reverse battery

protection guards the amplifier from an over-current condition due

to improper battery installation. For harsh environments, the

inputs can be taken 5V above the positive supply rail without

damage to the device.

The maximum recommended supply voltage is as high as 16V

and

ensured

operation

down

to

2.5V,

with

electrical

characteristics specified at 2.7V, 5V, and 15V. The 2.5V

operation makes it compatible with Li-Ion battery-powered

systems and many micro-power microcontrollers.
