The TLV854x ultra-low-power operational amplifiers (op amps) are intended forcost-optimized sensing applications in wireless and low-power wired equipment. The TLV854x familyof op amps minimize power consumption in equipment such as motion detecting security systems (likemicrowave and PIR motion sensing) where operational battery life is critical. They also have acarefully designed CMOS input stage, enabling very low, femto-ampere bias currents, therebyreducing IBIAS and IOS errors that would otherwiseimpact 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 suchas mobile phones, WiFi, radio transmitters and tab readers.
The TLV854x op amps operates with a single supply voltage down to 1.7 V supply, providingcontinuous performance in low battery situations over the extended temperature range of –40°C to+125°C. All versions are specified for operation from –40°C to 125°C. The TLV8541 (single version)is available in the 5-pin SOT-23 while the TLV8542 (dual version) is available in the 8-pin SOICpackage. The 4-channel TLV8544 (quad version) is available in the industry standard 14-pin TSSOPpackage.
