The TLV8544 ultra-low-power operational amplifier (op amps) is intended for
cost-optimized sensing applications in wireless and low-power wired equipment. The TLV8544 op amp
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-ampere bias currents, thereby reducing
IBIAS and IOS errors that would otherwise impact
sensitive applications. Examples of these include 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 such as mobile
phones, WiFi, radio transmitters and tab readers.
The TLV8544 op amp operates with a single supply voltage down to 1.7 V supply, providing
continuous performance in low battery situations over the extended temperature range of –40°C to
+125°C. The 4-channel TLV8544 is available in the industry standard 14-pin TSSOP package.
