... Frequency (Hz) http://www.cirrus.com 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 ...

... 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 ...

... Open-loop Gain and Stability Compensation 3.2.1 Discussion The CS3001 and CS3002 achieve ultra-high open loop gain. Figure 16 illustrates the amplifier in a non-inverting gain configuration. The open loop gain and phase plots indicate that the amplifier is stable for closed-loop gains less than 50 V/V and R1 ≤ ...

... V+ supply. The current through this pull-up re- sistor is the main source of current drain in the powerdown state. 3.4 Applications The CS3001 and CS3002 amplifiers are optimum for applications that require high gain and low drift. Figure 19 illustrates a thermopile amplifier with a gain of 650 V/V. The thermopile outputs only a few millivolts when subjected to infrared radiation ...
