LMH6601 250 MHz, 2.4V CMOS Op Amp with Shutdown
LMH6601
250 MHz, 2.4V CMOS Op Amp with Shutdown
General Description
The LMH6601 is a low voltage (2.4V 5.5V), high speed
voltage feedback operational amplifier suitable for use in a
variety of consumer and industrial applications. With a band-
width of 125 MHz at a gain of +2 and guaranteed high output
current of 100 mA, the LMH6601 is an ideal choice for video
line driver applications including HDTV. Low input bias cur-
rent (50 pA maximum), rail-to-rail output, and low current
noise allow the LMH6601 to be used in various industrial
applications such as transimpedance amplifiers, active fil-
ters, or high-impedance buffers. The LMH6601 is an attrac-
tive solution for systems which require high performance at
low supply voltages. The LMH6601 is available in a 6-pin
SC70 package, and includes a micropower shutdown fea-
ture.
