Texas Instruments TLC27L2CP Dual Precision Operational Amplifier, 65kHz, 8-Pin

The Texas Instruments TLC27L2CP is a dual precision operational amplifier that merges a wide selection of input offset voltage grades with exceptionally low offset voltage drift, high input impedance, minimal power draw, and high gain. It is built using Texas Instruments' advanced silicon-gate LinCMOS™ technology, delivering far superior offset voltage stability compared to traditional metal-gate processes.

This combination of extremely high input impedance, low bias currents, and ultra-low power consumption makes it the perfect component for demanding applications requiring high gain, low frequency operation, and energy efficiency. These benefits, alongside excellent common-mode and supply voltage rejection, position this amplifier as an outstanding choice for both cutting-edge new designs and for upgrading existing systems. The LinCMOS™ technology allows it to offer many features associated with bipolar amplifiers, but without the associated high power consumption.

The device excels in single-supply operation, with a common-mode input voltage range that extends below the negative rail and an output voltage range that includes the negative rail. It is built with robust ESD-protection circuitry and designed-in latch-up immunity for enhanced reliability in challenging environments. Key performance characteristics include a very low typical input offset voltage drift of just 0.1µV per month (including the initial 30 days), a maximum trimmed offset voltage of 500µV at 5V, and typically low noise of 25nV/√Hz at 1kHz.

Its typical input impedance is an impressive 10¹²Ω, while consuming a mere 95µW of power at 5V, underscoring its ultra-low power design. Housed in a through-hole mount 8-pin DIP package, it is suited for prototyping, educational use, and industrial applications where precision and stability are paramount.
