Active dual CMOS op-amp for general-purpose signal conditioning
It operates from a single or split supply spanning 3 V to 16 V, drawing 1.9 mA per channel. The CMOS input stage delivers an input bias current of just 0.7 pA, making it suitable for high-impedance sensor interfaces, active filters, and low-frequency signal conditioning in commercial-temperature equipment (0°C to 70°C).
3 V to 16 V supply — single-rail or split-rail flexibility
The supply span from 3 V to 16 V covers common single-supply rails (3.3 V, 5 V, 12 V) and split supplies (±1.5 V to ±8 V). The 3 V minimum allows operation in low-voltage battery-powered designs, while the 16 V maximum accommodates industrial control rails.
With a gain-bandwidth product of 2.2 MHz, the TLC277CD handles signals up to the low hundreds of kilohertz with closed-loop gain. The 5.3 V/µs slew rate supports full-output swings up to roughly 100 kHz without significant slew-induced distortion. This combination suits audio preamplifiers, active filters, and feedback compensation in switching regulators.
0.7 pA input bias — preserves signal integrity from high-impedance sources
Input offset voltage is 1.1 mV typical, adequate for precision DC measurements in commercial environments.
