Description The TLC2262 and TLC2264 are dual and quadruple operational amplifiers from Texas Instruments. Both devices exhibit rail-to-rail output performance for increased dynamic range in single- or split-supply applications. The TLC226x family offers a compromise between the micropower TLC225x and the ac performance of the TLC227x. It has low supply current for battery-powered applications, while still having adequate ac performance for applications that demand it. The noise performance has been dramatically improved over previous generations of CMOS amplifiers. Figure 1 depicts the low level of noise voltage for this CMOS amplifier, which has only 200 µA (typ) of supply current per amplifier.

The TLC2272CP is a dual low-noise rail-to-rail Operational Amplifier exhibits rail-to-rail output performance for increased dynamic range in single- or split-supply applications. The device offer comparable AC performance while having better noise, input offset voltage and power dissipation than existing CMOS operational amplifiers. The TLC227x has a noise voltage of 9nV/Hz, two times lower than competitive solutions. The TLC227x exhibiting high input impedance and low noise, is excellent for small-signal conditioning for high-impedance sources, such as piezoelectric transducers.
The TLC272CP is a Precision Dual Operational Amplifier combines a wide range of input offset voltage grades with low offset voltage drift, high input impedance, low noise and speeds approaching those of general-purpose BiFET devices. The device uses Texas Instruments silicon-gate LinCMOS™ technology, which provides offset voltage stability far exceeding the stability available with conventional metal-gate processes. The extremely high input impedance, low bias currents and high slew rates make these cost-effective devices ideal for applications previously reserved for BiFET and NFET products. Four offset voltage grades are available (C-suffix and I-suffix types), ranging from the TLC272 (10mV) to the high-precision TLC277 (500µV). These advantages, in combination with good common-mode rejection and supply voltage rejection, make these devices a good choice for new state-of-the-art designs as well as for upgrading existing designs.
