说明

The LMV796/LMV796Q (Single) and the LMV797 (Dual) low noise, CMOS input operational amplifiers offer a low input voltage noise density of 5.8 nV/√Hz while consuming only 1.15 mA (LMV796/LMV796Q) of quiescent current. The LMV796/LMV796Q and LMV797 are unity gain stable op amps and have gain bandwidth of 17 MHz. The LMV796/LMV796Q/ LMV797 have a supply voltage range of 1.8V to 5.5V and can operate from a single supply. The LMV796/LMV796Q/LMV797 each feature a rail-to-rail output stage capable of driving a 600Ω load and sourcing as much as 60 mA of current.

The LMV796/LMV796Q family provides optimal performance in low voltage and low noise systems. A CMOS input stage, with typical input bias currents in the range of a few femtoAmperes, and an input common mode voltage range, which includes ground, make the LMV796/LMV796Q and the LMV797 ideal for low power sensor applications.

The LMV796/LMV796Q/LMV797 are manufactured using TI’s advanced VIP50 process. The LMV796/ LMV796Q are offered in 5–pin SOT-23 package. The LMV797 is offered in 8–pin VSSOP package.
