Texas Instruments TLV8811/TLV8812 Precision Operational Amplifiers
Texas Instruments TLV8811/TLV8812 Precision Operational Amplifiers are ultra-low-power op amps ideal for cost-optimized, “Always ON” sensing applications in battery-powered wireless and low power wired equipment. These devices come with 6kHz bandwidth from 425nA of quiescent current and a trimmed offset voltage to under 500µV.
These amplifiers provide high precision while minimizing power consumption in equipment such as CO gas detectors and portable electronic devices where operational battery life is critical. Texas Instruments TLV8811/TLV8812 also have a CMOS input stage enabling fempto-amp bias currents, thereby reducing IBIAS and IOS errors that would otherwise impact high source impedance sensing applications. Additionally, built-in EMI protection reduces sensitivity to unwanted RF signals from mobile phones, WiFi, radio transmitters, and tag readers.
