The TLV8811 (single) and 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 500µV, 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 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.

The TLV8811 (single) and TLV8812 (dual) channel versions are available in industry standard 5-pin SOT-23 and 8-pin VSSOP packages respectively.
