... 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 ...

... 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 ≤ ...

... Powerdown (PDWN) The CS3001 single amplifier provides a power- down function on pin 1. If this pin is left open the amplifier will operate normally. If the powerdown is asserted low, the amplifier will go into a low power state. There is a pull-up resistor (approxi- mately 800 kΩ ...

... 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. The amplifier is compensated and bandlimited combination with R2 ...
