3 Description

The LPV801 (single) and LPV802 (dual) comprise a

family of ultra-low-power operational amplifiers for

“Always ON” sensing applications in wireless and low

power wired equipment. With 8kHz of bandwidth from

320nA of quiescent current, the LPV80x amplifiers

minimize power consumption in equipment such as

CO detectors, smoke detectors and motion detecting

security systems where operational battery-life is

critical.

In addition to being ultra-low-power, the LPV80x

amplifiers have CMOS input stages with typically

femto-amp

bias

currents

which

reduces

errors

commonly introduced in transimpedance amplifier

(TIA)

configurations

with

megaohm

feedback

resistors

and

high

source

impedance

sensing

applications. The LPV80x amplifiers also feature a

negative-rail sensing input stage and a rail-to-rail

output stage that is capable of swinging within

millivolts of the rails, maintaining the widest dynamic

range possible. EMI protection is designed into the

LPV80x in order to reduce system sensitivity to

unwanted RF signals from mobile phones, WiFi, radio

transmitters and tag readers.

The LPV80x amplifiers operate with a total supply

voltage

as

low

as

1.6V,

ensuring

continuous

performance in low battery situations over the

extended temperature range of –40ºC to 125ºC. The

single and dual channel versions are available in

industry standard 5-pin SOT-23 and 8-pin VSSOP

packages respectively.
