Matched Resistor Networks for Precision Amplifier Applications
Design Note 502

Introduction
Some ideal op amp conп¬Ѓgurations assume that the
feedback resistors exhibit perfect matching. In practice,
resistor non-idealities can affect various circuit parameters such as common mode rejection ratio (CMRR),
harmonic distortion and stability. For instance, as
shown in Figure 1, a single-ended ampliп¬Ѓer conп¬Ѓgured
to level-shift a ground-referenced signal to a common
mode of 2.5V needs a good CMRR. Assuming 34dB
CMRR and no input signal, this 2.5V level shifter exhibits
an output offset of 50mV, which can even overwhelm
the LSB and offset errors of 12-bit ADCs and drivers.

Precision Fully Differential Op Amp Drives High Resolution
ADCs at Low Power
Kris Lokere The LTC6362 op amp produces differential outputs, making it ideal for processing
fully differential analog signals or taking a single-ended signal and converting it
to fully differential. Many alternative op amps of this fully differential nature are
optimized for very high speed operation, resulting in high power consumption and
lack DC accuracy. The LTC6362 is unique in that it features differential outputs,
low power consumption and accurate DC offset voltage (see Table 1).
HOW DOES IT WORK? LetвЂ™s take a closer look at how a differential op amp works. Just like a regular
op amp, it has two inputs, but unlike a
regular op amp, it also has two outputs,
labeled вЂ“OUT and +OUT. A regular op amp
features high open-loop gain between the
differential input and the one output; a
fully differential op amp features high
open-loop gain between the differential input and the differential output.
Feedback should also be applied differentially. Figure 1 shows four external resistors feeding a portion of the
differential output back into the differential input. Just like in a regular RI VCM +
