Figure 9. Ultralow Noise Chopper Amplier
to achieve an extraordinarily low noise and low DC drift.
The performance of this circuit is suited for the demand-
ing transducer signal conditioning situations such as high
resolution scales and magnetic search coils.
The LTC1799’s output is divided down to form a 2-phase
925Hz square wave clock. This frequency, harmonically
unrelated to 60Hz, provides excellent immunity to harmonic
beating or mixing effects which could cause instabilities.
S1 and S2 receive complementary drive, causing A1 to
see a chopped version of the input voltage. A1’s square
wave output is synchronously demodulated by S3 and
S4. Because these switches are synchronously driven
with the input chopper, proper amplitude and polarity
information is presented to A2, the DC output amplier.
This stage integrates the square wave into a DC voltage,
providing the output. The output is divided down (R2 and
R1) and fed back to the input chopper where it serves as
a zero signal reference. Gain, in this case 1000, is set by
the R1-R2 ratio. Because A1 is AC coupled, its DC offset
and drift do not affect the overall circuit offset, resulting
in the extremely low offset and drift noted. The JFETs
have an input RC damper that minimizes offset voltage
contribution due to parasitic switch behavior, resulting in
the 1μV offset specication.
