SOT-23 Superbeta Op Amp Saves Board Space
in Precision Applications вЂ“ Design Note 266
Glen Brisebois
INTRODUCTION
The tiny new LTВ®1880 achieves precision unprecedented
in a SOT-23 package without resorting to autozeroing
techniques. Input offset voltage and drift are typically
40ОјV and 0.3ОјV/В°C, respectively, with guarantees of
200ОјV and 1.2ОјV/В°C maximum over temperature. The
device operates on total supplies from 2.7V to 40V with
rail-to-rail outputs, giving a dynamic range of 120dB.
Unlike some competitorsвЂ™ SOT-23 op amps, which claim
to maintain good precision, the LT1880 supports its
input precision with a high open loop gain of 1.6 million, as well as 135dB CMRR and PSRR. It is available
in commercial and industrial temperature grades.
APPLICATIONS
Getting Rail-to-Rail Operation without
Rail-to-Rail Inputs
The LT1880 does not have rail-to-rail inputs, but for
most inverting applications and noninverting gain
applications, this is largely inconsequential. Figure 1
shows the basic op amp conп¬Ѓgurations, what happens
to the op amp inputs, and whether or not the op amp …

DESIGN FEATURES LT1880 SOT-23 Op Amp Saves
Board Space in Precision Applications
by Glen Brisebois Introduction
The tiny new LT1880 achieves precision unprecedented in a SOT-23
package without resorting to autozeroing techniques. Input offset
voltage and drift are typically 40ВµV
and 0.3ВµV/В°C, respectively, with
guarantees of 200ВµV and 1.2ВµV/В°C
maximum over temperature. The
device operates on total supplies from
2.7V to 40V with rail-to-rail outputs,
giving a dynamic range of 120dB.
Unlike some competitorsвЂ™ SOT-23 op
amps, which claim to maintain good
precision, the LT1880 supports its
input precision with a high open loop
gain of 1.6 million, as well as 135dB
CMRR and PSRR. It is available in
commercial and industrial temperature grades. The circuit of Figure 2 shows an
extreme example of the inverting case.
The input voltage at the 1M resistor
can swing В±13.5V and the LT1880
will output an inverted, divided-byten version of the input voltage. The …
