description
The TLV2254 and TLV2254A are quadruple
operational amplifiers manufactured using Texas
Instruments Advanced LinCMOS
process.
These devices are optimized and fully specified
for single-supply 3-V and 5-V operation. For this
low-voltage operation combined with micropower
dissipation levels, the input noise-voltage
performance has been dramatically improved
using optimized design techniques for CMOS-
type amplifiers. Another added benefit is that
these amplifiers exhibit rail-to-rail output swing.
Figure 1 graphically depicts the high-level output
voltage for different levels of output current for a
3-V single supply. The output dynamic range can
be extended using the TLV2254 with loads
referenced midway between the rails. The
common-mode input voltage range is wider than
typical standard CMOS-type amplifiers. To take
advantage of this improvement in performance
and to make this device available for a wider range
of applications, V
ICR
is specified with a larger
maximum input offset voltage test limit of
±
5 mV, allowing a minimum of 0 to 2-V common-mode input voltage range for a 3-V supply. Furthermore, at
35
μ
A (typical) of supply current per amplifier, the TLV2254 family can achieve input offset voltage levels as
low as 850
μ
V outperforming existing CMOS amplifiers.
