3 Description

The TLC2272AM-MIL device is a dual operational

amplifier from Texas Instruments. The device exhibits

rail-to-rail output performance for increased dynamic

range in single- or split-supply applications. The

TLC2272AM-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 TLC2272AM-MIL device has a noise

voltage of 9 nV/√Hz, two times lower than competitive

solutions.

The TLC2272AM-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 TLC2272AM-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.
