Working Principle

The TLC252CD is a dual, low-power CMOS operational amplifier. It consists of two independent, high-performance differential-input amplifiers, which feature wide bandwidth, high gain, and rail-to-rail swings. The amplifiers are powered by a single supply voltage, VCC, which can range from 2.7V to 18V. The internal circuitry of the TLC252CD draws only a fraction of the power needed by conventional operational amplifiers. This low-power requirement allows the TLC252CD to be powered by batteries or other low-power sources. Additionally, the TLC252CD is unity gain stable, ensuring stable operation even under high gain circuit conditions. The TLC252CD features a low input offset voltage, which minimizes the output offset voltage and helps to maintain accuracy over time. It also features excellent input/output common-mode rejection ratios, wide supply voltage range and rail-to-rail output swings for improved dynamic performance. Finally, the device is protected from latch-up and short-circuit damage with an on-chip thermal shutdown protection circuit.

In short, the TLC252CD is a versatile, high-performance, low-power CMOS operational amplifier ideal for a wide variety of general purpose instrumentation and precision tracking applications. It features low power requirements, an improved input/output common-mode rejection ratio, unity gain stability, and protective circuitry to extend the life and performance of the device.
