SNOSD29D – DECEMBER 2016 – REVISED NOVEMBER 2017 TLV854x 500-nA, RRIO, Nanopower Operational Amplifiers for Cost-Optimized Systems
1 Features 3 Description The TLV854x ultra-low-power operational amplifiers
(op amps) are intended for cost-optimized sensing
applications in wireless and low-power wired
equipment. The TLV854x family of op amps minimize
power consumption in equipment such as motion
detecting security systems (like microwave and PIR
motion sensing) where operational battery life is
critical. They also have a carefully designed CMOS
input stage, enabling very low, femto-ampere bias
currents, thereby reducing IBIAS and IOS errors that
would otherwise impact sensitive applications.
Examples of these include transimpedance amplifier
(TIA) configurations with megaohm feedback
resistors, and high source impedance sensing
applications. Additionally, built-in EMI protection …
