3 Description

The TLV8811 (single) and TLV8812 (dual) family of

precision ultra-low-power operational amplifiers are

ideal for cost-optimized, “Always ON” sensing

applications in battery powered wireless and low

power wired equipment. With 6 kHz of bandwidth

from 425 nA of quiescent current and a trimmed

offset voltage to under 500μV, the TLV881x

amplifiers provide high precision while minimizing

power consumption in equipment such as CO gas

detectors and portable electronic devices where

operational battery-life is critical. They also have a

CMOS input stage enabling fempto-amp bias

currents, thereby reducing IBIAS and IOS errors that

would otherwise impact high source impedance

sensing applications. Additionally, built-in EMI

protection reduces sensitivity to unwanted RF signals

from mobile phones, WiFi, radio transmitters, and tag

readers.

The TLV8811 (single) and TLV8812 (dual) channel

versions are available in industry standard 5-pin SOT-

23 and 8-pin VSSOP packages respectively.
