HIGH SPEED/LOW POWER 17MHz RAIL-TO-RAIL INPUT-OUTPUT

OPERATIONAL AMPLIFIERS

General Description

Using patent pending new circuit topologies, the LM6142 provides new levels of performance

in applications where low voltage supplies or power limitations previously made compromise

necessary. Operating on supplies of 2.7V to 24V, the LM6142 is an excellent choice for

battery operated systems, portable instrumentation and other applications.

The greater than rail-to-rail input voltage range eliminates concern over exceeding the

common-mode voltage range. The rail-to-rail output swing provides the maximum possible

dynamic range at the output. This is particularly important when operating on low supply

voltages.

High gain-bandwidth with 650uA/Amplifier supply current opens new battery powered

applications where previous higher power consumption reduced battery life to unacceptable

levels. The ability to drive large capacitive loads without oscillating functionally

removes this common problem.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.

Operating Ratings indicate conditions for which the device is functional, but do not

guarantee specific performance limits. For guaranted specifications and the test

conditions, see the Electrical Characteristics. The guaranteed specifications apply

only for the test conditions listed. Some performance characteristics may degrade

when the device is not operated under the listed test conditions.

Note 2: The maximum power dissipation must be derated at elevated temperatures and is

dectated by Tjmax (maximum junction temperature), ThetaJA (package junction to

ambient thermal resistance), and TA (ambient temperature). The maximum allowable

power dissipation at any temperature is Pdmax = (Tjmax - TA) /ThetaJA or the number

given in the Absolute Maximum Ratings, whichever is lower.

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 150 C.
