運算放大器，英文資料詳細解說。 能夠讓我們了解運算放大器的內部結構和參數特性。

FEATURES DESCRIPTION 2 Low voltage operation and low power dissipation ? （Typical Unless Otherwise Noted） make the LMC6574/2 ideal for battery-powered ? Guaranteed 2.7V and 3V Performance systems. ? Rail-to-Rail Output Swing （Within 5 mV of 3V amplifier performance is backed by 2.7V Supply Rail， 100 kΩ Load） guarantees to ensure operation throughout battery ? Ultra-Low Supply Current： 40 μA/Amplifier lifetime. These guarantees also enable analog circuits ? Low Cost to operate from the same 3.3V supply used for digital logic. ? Ultra-Low Input Current： 20 fA ? High Voltage Gain @ V Battery life is maximized because each amplifier S=2.7V， R dissipates only micro-watts of power. L=100 kΩ： 120 dB ? Specified for 100 kΩ and 5 kΩ Loads The LMC6574/2 does not sacrifice functionality for low voltage operation. The LMC6574/2 generates ? Available in VSSOP Package 120 dB of open-loop gain just like a conventional amplifier， but the LMC6574/2 can do this from a 2.7V APPLICATIONS supply. ? Transducer Amplifier These amplifiers are designed with features that ? Portable or Remote Equipment optimize low voltage operation. The output voltage ? Battery-Operated Instruments swings rail-to-rail to maximize signal-to-noise ratio and dynamic signal range. The common-mode input ? Data Acquisition Systems voltage range extends from 800 mV below the ? Medical Instrumentation positive supply to 100 mV below ground. ? Improved Replacement for TLV2322 and This device is built with Texas Instruments‘ advanced TLV2324 Double-Poly Silicon-Gate CMOS process. LMC6572 is also available in VSSOP package which is almost half the size of a SOIC-8 device.
