3. CS3011/CS3012 OVERVIEW
The CS301 1/CS3012 amplifiers are de signed for
precision measu rement o f sign als from DC to
1 kHz when opera ting from a supply voltage of
+2.7 V to +6.7 V (± 1.35 to ± 3.35 V). The amplifi-
ers are designed with a patented architecture that
utilizes multiple amplifier stages to yield very high
open loop gain at frequencies of 1 kHz and below.
The amplifiers yield low noise and low offset dr ift
while consuming relatively low supply current . An
increase in noise floor above 1 kHz is the result of
intermediate stages of the amplifier being operated
at very low currents. The amplifiers are intende d
for amplifying small signals with large gains in ap-
plications where the output of the amplifier can be
band-limited to frequencies below 1 kHz.
