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. Each channel can source or sink up to 30 mA, enough to drive moderate loads like ADC inputs or small relays.
2.2 MHz GBW and 5.3 V/µs slew rate — bandwidth for audio and control loops
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
The CMOS input stage keeps input bias current at 0.7 pA typical, which minimises voltage offset errors when driven from high-impedance sources such as photodiodes, pH probes, or piezoelectric sensors. Input offset voltage is 1.1 mV typical, adequate for precision DC measurements in commercial environments.
