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 reduces sensitivity to unwanted RF signals from sources such as mobile phones, WiFi, radio transmitters and tab readers.
