3 Description

The TLV8801 (single) and TLV8802 (dual) family of

ultra-low-power operational amplifiers are ideal for

cost-optimized sensing applications in wireless and

low power wired equipment. The TLV880x amplifiers

minimize power consumption in equipment such as

CO detectors, smoke detectors and motion detecting

security systems (like PIR motion sensing) where

operational battery-life is critical. They also have a

carefully designed CMOS input stage enabling very

low, femto-amp bias currents, thereby reducing IBIAS

and IOS errors that would otherwise impact sensitive

applications like transimpedance amplifier (TIA)

configurations with megaohm feedback resistors, and

high source impedance sensing applications.

Additionally, built-in EMI protection reduces sensitivity

to unwanted RF signals from sources like mobile

phones, WiFi, radio transmitters and tag readers.

The TLV8801 (single) and TLV8802 (dual) channel

versions are available in industry standard 5-pin SOT-

23 and 8-pin VSSOP packages respectively.
