Noise Degradation
The LTC
廬
1052 and LTC7652 are low noise zero-drift op
amps manufactured using Linear Technology鈥檚 enhanced
LTCMOS
TM
silicon gate process. Chopper-stabilization
constantly corrects offset voltage errors. Both initial offset
and changes in the offset due to time, temperature and
common mode voltage are corrected. This, coupled with
picoampere input currents, gives these amplifiers
unmatched performance.
Low frequency (1/f) noise is also improved by the
chopping technique. Instead of increasing continuously
at a 3dB/octave rate, the internal chopping causes noise to
decrease at low frequencies.
The chopper circuitry is entirely internal and completely
transparent to the user. Only two external capacitors
are required to alternately sample-and-hold the offset
correction voltage and the amplified input signal. Control
circuitry is brought out on the 14-pin and 16-pin versions
to allow the sampling of the LTC1052 to be synchronized
with an external frequency source.
