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
carefully designed CMOS input stage enabling very
low, fempto-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. The TLV881x amplifiers also feature a
negative-rail sensing input stage and a rail-to-rail
output stage that swings within millivolts of the rails,
maintaining the widest dynamic range possible.
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.
