LMH6732
High Speed Op Amp with Adjustable Bandwidth
General Description
The LMH6732 is a high speed op amp with a unique com-
bination of high performance, low power consumption, and
flexibility of application. The supply current is adjustable,
over a continuous range of more than 10 to 1, with a single
resistor, R_P. This feature allows the device to be used in a
wide variety of high performance applications including de-
vice turn on/ turn off (Enable/ Disable) for power saving or
multiplexing. Typical performance at any supply current is
exceptional. The LMH6732’s design has been optimized so
that the output is well behaved, eliminating spurious outputs
on "Enable".
The LMH6732’s combination of high performance, low
power consumption, and large signal performance makes it
ideal for a wide variety of remote site equipment applications
such as battery powered test instrumentation and communi-
cations gear. Other applications include video switching ma-
trices, ATE and phased array radar systems.
The LMH6732 is available in the SOIC and SOT23-6 pack-
ages. To reduce design times and assist in board layout, the
LMH6732 is supported by an evaluation board.
