• Active RFID Readers and Tags

• Portable Medical Equipment


The TLV8544 ultra-low-power operational amplifier is ideal for cost-optimized sensing applications in wireless and low-power wired equipment. The TLV8544 amplifier minimizes power consumption in equipment such as motion detecting security systems (like microwave and PIR motion sensing) where operational battery life is critical. It also has a carefully designed CMOS input stage enabling very low, femto-amp bias currents, thereby reducing IBIAS and IOS errors that would otherwise impact sensitive applications like transimpedance amplifier (TIA) configurations with megaohm feedback resistors, and high source impedance sensing applicaitons. Additionally, built-in EMI protection reduces sensitivity to unwanted RF signals from sources like mobile phones, WiFi, radio transmitters and tab readers.


The TLV8544 amplifier operates with a single supply voltage down to 1.7V, providing continuous performance in low battery situations over the extended temperature range of -40ºC to 125ºC. The quad TLV8544 is available in the industry standard 14-pin TSSOP package.
