LTC1051/LTC1053 as AC Amplifiers
Although initially chopper stabilized op amps were de-
signed to minimize DC offsets and offset drifts, the
LTC1051/LTC1053 family, on top of its outstanding DC
characteristics, presents efficient AC performance. For
instance, at single 5V supply, each op amp typically
consumes 0.5mA and still provides 1.8MHz gain band-
width product and 3V/s slew rate. This, combined with
almost distortionless swing to the supply rails (Figure 8),
makes the LTC1051/LTC1053 op amps nearly general
purpose. To further expand this idea (the “aliasing” phe-
nomenon) which can occur under AC conditions, should
be described and properly evaluated.
Aliasing
The LTC1051/LTC1053 are equipped with internal cir-
cuitry to minimize aliasing. Aliasing, no matter how small,
occurs when the input signal approaches and exceeds the
internal sampling rate. Aliasing is caused by the sampled
data nature of the chopper op amps. A generalized study
of this phenomenon is beyond the scope of a data sheet;
however, a set of rules of thumb can answer many
questions:
1. Alias signals can be generally defined as output AC
signals at a frequency of nfCLK ±mfIN. The nfCLK term is the
internal sampling frequency of the chopper stabilized op
amps and its harmonics; mfIN is the frequency of the input
signal and its harmonics, if any.
