TLC2254CD

TLC2254CD Description

The TLC2254CD from Texas Instruments is a quad-channel general-purpose operational amplifier from the LinCMOS™ series, designed for precision analog applications. Packaged in a 14-SOIC tube, this surface-mount IC operates over a 4.4V to 16V supply range, making it suitable for both single and dual-supply configurations. With an ultra-low input bias current of 1 pA and a moderate gain bandwidth product of 210 kHz, it excels in low-power, high-impedance signal conditioning. The device features low input offset voltage (200 µV) and a slew rate of 0.12V/µs, ensuring stable performance in DC and low-frequency applications. Despite being obsolete, it remains RoHS3 compliant and REACH unaffected, adhering to environmental standards.
