APPLICATIONS

DESCRIPTION

The TLV270x combines sub-micropower operational

amplifier and comparator into a single package that

produces excellent micropower signal conditioning with

only 1.4

µA of supply current. This combination 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 5 V above the positive supply rail without damage

to the device.

The TLV270x’s low supply current is coupled with

extremely low input bias currents enabling them to be

used with mega-ohm resistors making them ideal for

portable, long active life, applications. DC accuracy is

ensured with a low typical offset voltage as low as

390

µV, CMRR of 90 dB, and minimum open loop gain

of 130 V/mV at 2.7 V.

The maximum recommended supply voltage is as high

as 16 V and ensured operation down to 2.5 V, with

electrical characteristics specified at 2.7 V, 5 V, and

15 V. The 2.5-V operation makes it compatible with

Li-Ion battery-powered systems and many micro-power

microcontrollers available today including TI’s MSP430.

All members are available in PDIP and SOIC with the

duals, one op-amp and one comparator, in the small

MSOP package and quads, two operational amplifiers

and two comparators, in the TSSOP package.
