The LMC6574/2 is ideal for battery-powered systems with low voltage operation and low power consumption.
The performance of the 3V amplifier supports 2.7V to guarantee the entire battery life to ensure operation. These warranties also enable the operation of analog circuits using the same 3.3V digital logic supply.
Because each amplifier consumes only microwatts of power, battery life is maximized.
The LMC6574/2 does not sacrifice functionality for low voltage operation. The LMC6574/2 produces 120 dB, just like a conventional amplifier with open-loop gain, but the LMC6574/2 can be powered from a 2.7V supply.
These amplifiers are designed with features that optimize low-voltage operation. The output voltage swings rail-to-rail to maximize the signal-to-noise ratio and dynamic signal range of the signal. The common-mode input voltage ranges from 800 millivolts below a positive supply of 100 mV below ground.
This equipment is built with the state's advanced bi-poly silicon gate CMOS process.
The LMC6572 is also available in an MSOP package, which is almost half the size of an SO-8 device.
