LMH6601
250 MHz, 2.4V CMOS Operational Amplifier with Shutdown
General Description
The LMH6601 is a low voltage (2.4V – 5.5V), high speed volt-
age feedback operational amplifier suitable for use in a variety
of consumer and industrial applications. With a bandwidth 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 current (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 filters, or high-
impedance buffers. The LMH6601 is an attractive solution for
systems which require high performance at low supply volt-
ages. The LMH6601 is available in a 6-pin SC70 package,
and includes a micropower shutdown feature.
