描述 The LMV793 (single) and the LMV794 (dual) CMOS input operational amplifiers offer a low input voltage noise density of 5.8 nV/√Hz while consuming only 1.15 mA (LMV793) of quiescent current. The LMV793/LMV794 are stable at a gain of 10 and have a gain bandwidth product (GBW) of 88 MHz. The LMV793/LMV794 have a supply voltage range of 1.8V to 5.5V and can operate from a single supply. The LMV793/LMV794 each feature a rail-to-rail output stage capable of driving a 600Ω load and sourcing as much as 60 mA of current.The LMV793/LMV794 provide optimal performance in low voltage and low noise systems. A CMOS input stage, with typical input bias currents in the range of a few femto-Amperes, and an input common mode voltage range, which includes ground, make the LMV793/LMV794 ideal for low power sensor applications where high speeds are needed.The LMV793/LMV794 are manufactured using TI’s advanced VIP50 process. The LMV793 is offered in either a 5-Pin SOT23 or an 8-Pin SOIC package. The LMV794 is offered in either the 8-Pin SOIC or the 8-Pin VSSOP.特性(Typical 5V Supply, Unless Otherwise Noted) Input Referred Voltage Noise 5.8 nV/√Hz Input Bias Current 100 fA Gain Bandwidth Product 88 MHz Supply Current per ChannelLMV793 1.15 mA LMV794 1.30 mARail-to-Rail Output Swing@ 10 kΩ Load 25 mV from Rail @ 2 kΩ Load 45 mV from RailEnsured 2.5V and 5.0V PerformanceTotal Harmonic Distortion 0.04% @1 kHz, 600Ω Temperature Range −40°C to 125°C All trademarks are the property of their respective owners.
