3 Description

The TLC2274AM-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 TLC2274AM-MIL device offers 2

MHz of bandwidth and 3 V/μs of slew rate for higherspeed

applications. Thee device offers comparable

ac performance while having better noise, input offset

voltage, and power dissipation than existing CMOS

operational amplifiers. The TLC2274AM-MIL device

has a noise voltage of 9 nV/√Hz, two times lower

than competitive solutions.

The TLC2274AM-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 TLC2274AM-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.
