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.
