Active dual CMOS op-amp for low-frequency precision
The TLC27M2CPW: It operates from a single or split supply spanning 3 V to 16 V, drawing 285 µA per channel. The 0.7 pA input bias current makes it suitable for high-impedance sensor interfaces such as photodiode amplifiers, pH probe buffers, and precision integrators where bias current error must be minimized. The 30 mA output current per channel can drive moderate loads like ADC inputs or small relays.
The 635 kHz gain-bandwidth product sets the usable closed-loop bandwidth.
285 µA per channel — power budget anchor
At 285 µA per channel, the TLC27M2CPW draws about 570 µA total for both amplifiers. This is low enough for battery-powered instruments, multi-channel data loggers, or always-on sense amplifiers where every microamp counts. The 3 V minimum supply allows operation from two alkaline cells or a single lithium coin cell. Compare this to a general-purpose op-amp drawing 2 mA per channel — the TLC27M2CPW saves over 1.4 mA per channel, which can double battery life in a two-channel design.
For dual-sourcing, note that the OPA4374AIPWT is a quad CMOS op-amp with higher bandwidth (6.5 MHz) and rail-to-rail output, but it is not a pin-compatible drop-in — it is a different package and pinout.
