10MHz、低噪声、低电压和低功耗运算放大器 - LMV721-N


  • LMV721  - 器件与被比较器件在功能和参数上完全等效。 


The LMV721-N (Single) and LMV722 (Dual) are low noise, low voltage, and low power op amps, that can be designed into a wide range of applications. The LMV721-N/LMV722 has a unity gain bandwidth of 10MHz, a slew rate of 5V/us, and a quiescent current of 930uA/amplifier at 2.2V.

The LMV721-N/722 are designed to provide optimal performance in low voltage and low noise systems. They provide rail-to-rail output swing into heavy loads. The input common-mode voltage range includes ground, and the maximum input offset voltage are 3.5mV (Over Temp) for the LMV721-N/LMV722. Their capacitive load capability is also good at low supply voltages. The operating range is from 2.2V to 5.5V.

The chip is built with TI's advanced Submicron Silicon-Gate BiCMOS process. The single version, LMV721-N, is available in 5 pin SOT-23 and a SC70 (new) package. The dual version, LMV722, is available in an SOIC-8 and VSSOP-8 package.
