1.7V, 500nA, RAIL-TO-RAIL INPUT/OUTPUT, NANOPOWER OPERATIONAL AMPLIFIER

DESCRIPTION

The UTC ULV8562 ultra-low-power operational amplifier (op

amps) is intended for cost-optimized sensing applications in

wireless and low-power wired equipment. The UTC ULV8562

family of op amps minimizes power consumption in equipment

such as motion detecting security systems where operational

battery life is critical. It also has 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

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.
