TLV8812 Nanopower Operational Amplifier

Texas Instruments’ TLV8812 (dual) family of precision ultra-low-power operational amplifiers are ideal for cost-optimized, “Always ON” sensing applications in battery powered wireless and low power wired equipment. With 6 kHz of bandwidth from 425 nA of quiescent current and a trimmed offset voltage to under 500 µV, the TLV881x 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. They also have a CMOS input stage enabling femto-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, Wi-Fi, radio transmitters, and tag readers.
