The TLC2272-Q1 and TLC2274-Q1 devices 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 TLC227x-Q1 family offers 2 MHz of bandwidth and 3 V/µs of slew rate for higher-speed applications. These devices offer comparable AC performance while having better noise, input offset voltage, and power dissipation than existing CMOS operational amplifiers. The TLC227x‑Q1 has a noise voltage of 9 nV/√Hz, two times lower than competitive solutions.
The TLC227x-Q1, exhibiting high input impedance and low noise, is excellent for small-signal conditioning for high-impedance sources, such as piezoelectric transducers. In addition, the rail-to-rail output feature, with single- or split-supplies, makes this family a great choice when interfacing with analog-to-digital converters (ADCs). For precision applications, the TLC227xA-Q1 family is available with a maximum input offset voltage of 950 µV. This family is fully characterized at 5 V and ±5 V.
They offer increased output dynamic range, lower noise voltage, and lower input offset voltage. This enhanced feature set allows them to be used in a wider range of applications. For applications that require higher output drive and wider input voltage range, see the TLV2432-Q1 and TLV2442-Q1 devices. All of the parameters of the TLC227x-Q1 family enables the device to be applicable in most automotive applications.
