The TLC2274 is a quadruple operational amplifier from Texas Instruments. The device exhibits rail-to-rail output performance for increased dynamic range in single- or split-supply applications. The TLC2274 offers 2 MHz of bandwidth and 3 V/μs of slew rate for higher speed applications. These device offers comparable ac performance while having better noise, input offset voltage, and power dissipation than existing CMOS operational amplifiers. The TLC2274 has a noise voltage of 9nV/√Hz, two times lower than competitive solutions.
The TLC2274, exhibiting high input impedance and low noise, is excellent for small-signal conditioning for high-impedance sources, such as piezoelectric transducers. Because of the micropower dissipation levels, this device works well in hand-held monitoring and remote-sensing applications. In addition, the rail-to-rail output feature, with single- or split-supplies, makes this device a great choice when interfacing with analog-to-digital converters (ADCs). This family is fully characterized at 5 V and ±5 V.
It offers increased output dynamic range, lower noise voltage, and lower input offset voltage. This enhanced feature set allows the device to be used in a wider range of applications.
