描述 Description

The TLC2274M-MIL device 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 TLC2274M-MIL device offers 2 MHz of bandwidth and 3 V/μs of slew rate for higher-speed applications. Thee device offers comparable ac performance while having better noise, input offset voltage, and power dissipation than existing CMOS operational amplifiers. The TLC2274M-MIL device has a noise voltage of 9 nV/√Hz, two times lower than competitive solutions.

The TLC2274M-MIL device, 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, the 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). For precision applications, the TLC2272AM-MIL device is available with a maximum input offset voltage of 950?μV. This device is fully characterized at 5 V and ±5 V.

The TLC2274M-MIL device also makes a great upgrade to the TLC272 in standard designs, offering 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. For applications that require higher output drive and wider input voltage range, see the TLV2432 and TLV2442 devices.

If the design requires single amplifiers, see the TLV2211, TLV2221 and TLV2231 family. These devices are single rail-to-rail operational amplifiers in the SOT-23 package. Their small size and low power consumption make them ideal for high density, battery-powered equipment.
