3 Description
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.
