Ultra Low Noise Op Amp Combines Chopper and
Bipolar Op Amps вЂ“ Design Note 36
Nello Sevastopoulos
low noise voltage of the LTВ®1007 precision bipolar op
amp appears in Figure 1. This composite op amp can,
for instance, be used as a strain gauge ampliп¬Ѓer. One
half of the LTC1051 dual chopper op amp, LTC1051,
integrates the small LT1007 input offset voltage and
applies a DC correction voltage at its pin-8 via divider
(R2, R3). The other half of the LTC1051, buffers the VOS
nulling circuitry eliminating loading at input A. Resistors R1, R2, R3 allow the integrator full output swing
assuring VOS correction of the LT1007. The ratio of R3
to R2 is made as high as possible to limit noise injection
of the chopper into pin-8 of the bipolar op amp. The
total measured input VOS was 2ОјV, with a 10nV/В°C drift. Chopper op amp technology has continuously improved.
Contemporary single, dual and quad low noise chopper
op amps (LTCВ®1050/51/53), with internal sample and
hold capacitors, are compatible with industry standard
op amp sockets.
Chopper op amps are mainly used to amplify small DC
signals and these applications require excellent VOS, VOS
drift, low bias current and low noise. The outstanding
VOS performance of chopper op amps is well known. …

Chopper vs Bipolar Op AmpsвЂ”An Unbiased Comparison
Design Note 42
George Erdi Table 1 lists the parameters of importance. In all input
parameters (except noise) the advantage unquestionably goes to the choppers. 5ОјV maximum offset voltage, 0.5ОјV/В°C maximum drift are commonly found
