PACKAGE INFORMATION

The RH1498 is a dual, rail-to-rail input and output precision

C-Load™ op amp with a 10MHz gain-bandwidth product

and a 6V/μs slew rate.

The RH1498 is designed to maximize input dynamic range

by delivering precision performance over the full supply

voltage. Using a patented technique, the input stages of

the RH1498 are trimmed, one at the negative supply and

the other at the positive supply. The resulting guaranteed

common mode rejection is much better than other rail-to-

rail input op amps. When used as a unity-gain buffer in front

of single supply 12-bit A-to-D converters, the RH1498 is

guaranteed to add less than 1LSB of error even in single

3V supply systems.

With 110dB of supply rejection, the RH1498 maintains its

performance over a supply range of 2.2V to 36V. The inputs

can be driven beyond the supplies without damage or phase

reversal of the output. These op amps remain stable while

driving capacitive loads up to 10,000pF.

The wafer lots are processed to Linear Technology's in-

house Class S flow to yield circuits usable in stringent

military and space applications.
