3 Description
The LM7301 provides high performance in a wide
range of applications. The LM7301 offers greater than
rail-to-rail input range, full rail-to-rail output swing,
large capacitive load driving ability, and low distortion.
With only 0.6-mA supply current, the 4-MHz gain-
bandwidth of this device supports new portable
applications where higher power devices
unacceptably drain battery life.
The LM7301 can be driven by voltages that exceed
both power supply rails, thus eliminating concerns
over exceeding the common-mode voltage range.
The rail-to-rail output swing capability provides the
maximum possible dynamic range at the output. This
is particularly important when operating on low supply
voltages.
Operating on supplies of 1.8 V to 32 V, the LM7301 is
excellent for a very wide range of applications in low
power systems.
Placing the amplifier right at the signal source
reduces board size and simplifies signal routing. The
LM7301 fits easily on low profile PCMCIA cards.
