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 I_BIAS
and I_OS 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.
