Description
The CS3001 single amplifier and the CS3002 dual am-
plifier are designed for precision amplification of low-
level signals and are ideally suited to applications that
require very high closed-loop gains. These amplifiers
achieve excellent offset stability, super-high open-loop
gain, and low noise over time and temperature. The de-
vices also exhibit excellent CMRR and PSRR. The
common mode input range includes the negative supply
rail. The amplifiers operate with any total supply voltage
from 2.7 V to 6.7 V (±1.35 V to ±3.35 V).

... Open-loop Gain and Phase Response Figure 15 illustrates the open loop gain and phase response of the CS3001/CS3002. The gain slope of the amplifier is about –100 dB/decade between 500 Hz and 60 kHz and transitions to –20 dB/de- cade between 60 kHz and its unity gain crossover frequency at about 4.8 MHz. Phase margin at unity gain is about 70 degrees ...
