LM7301
Low Power, 4 MHz GBW, Rail-to-Rail Input-Output
Operational Amplifier in TinyPak
TM
Package
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 1.8V32V, 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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2: Human body model, 1.5 k
in series with 100 pF.
Note 3: Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150C.
Note 4: The maximum power dissipation is a function of T
J(max)
,
JA
, and T
A
. The maximum allowable power dissipation at any ambient temperature is P
D
= (T
J(max)
- T
A
)/
JA
. All numbers apply for packages soldered directly into a PC board.
Note 5: Typical Values represent the most likely parametric norm.
Note 6: All limits are guaranteed by testing or statistical analysis.
