Texas Instruments TLV8801/TLV8802 Dual Nanopower Op Amps
Texas Instruments TLV8801/TLV8802 Dual Nanopower Operational Amplifiers are ideal for cost-optimized sensing applications in wireless and low-power wired equipment. The TLV8801/TLV8802 amplifiers minimize power consumption in equipment. Typical equipment includes CO detectors, smoke detectors, and motion-detecting security systems where operational battery life is critical. The Texas Instruments TLV8801/TLV8802 has a carefully designed CMOS input stage enabling very low, Femto-amp bias currents, reducing IBIAS and IOS errors. These errors would otherwise impact sensitive applications like 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 like mobile phones, WiFi, radio transmitters, and tag readers.Features
