The TLC225x and TLC225xA are advanced LinCMOS rail-to-rail very low-power operational amplifiers that offer a range of features and benefits. The output swing of these amplifiers includes both supply rails, allowing for flexibility in application. With low noise of 19 nV/√Hz at f = 1 kHz and low input bias current of 1 pA, these amplifiers deliver high performance. These operational amplifiers are fully specified for both single-supply and split-supply operation, making them versatile and suitable for a variety of circuit configurations. With very low power consumption of only 35 µA per channel, they are energy efficient and well-suited for battery-powered applications. The common-mode input voltage range of these amplifiers includes the negative rail, providing a wide input range for enhanced functionality. Additionally, the low input offset voltage of 850 µV max at TA ensures accurate and precise signal processing. Overall, the TLC225x and TLC225xA operational amplifiers offer a combination of high performance, energy efficiency, and versatility, making them ideal for a wide range of applications in electronics and circuit design.
