LMV861/LMV862

30 MHz Low Power CMOS, EMI Hardened Operational

Amplifiers

General Description

National’s LMV861 and LMV862 are CMOS input, low power

op amp IC's, providing a low input bias current, a wide tem-

perature range of −40°C to +125°C and exceptional perfor-

mance making them robust general purpose parts. Addition-

ally, the LMV861 and LMV862 are EMI hardened to minimize

any interference so they are ideal for EMI sensitive applica-

tions.

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 MSOP.
