说明

TI’s LMV861 and LMV862 are CMOS input, low power op amp IC's, providing a low input bias current, a wide temperature range of −40°C to +125°C and exceptional performance making them robust general purpose parts. Additionally, the LMV861 and LMV862 are EMI hardened to minimize any interference so they are ideal for EMI sensitive applications.

The unity gain stable LMV861 and LMV862 feature 30 MHz of bandwidth while consuming only 2.25 mA of current per channel. These parts also maintain stability for capacitive loads as large as 200 pF. The LMV861 and LMV862 provide superior performance and economy in terms of power and space usage.

This family of parts has a maximum input offset voltage of 1 mV, a rail-to-rail output stage and an input common-mode voltage range that includes ground. Over an operating range from 2.7V to 5.5V the LMV861 and LMV862 provide a PSRR of 93 dB, and a CMRR of 93 dB. The LMV861 is offered in the space saving 5-Pin SC70 package, and the LMV862 in the 8-Pin VSSOP.
