LM7301

Low Power, 4 MHz GBW, Rail-to-Rail Input-Output

General 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 driv-

ing 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 oper-

ating on low supply voltages.

Operating on supplies of 1.8V–32V, 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.
