RH1499M
10MHz, 6V/µs, Quad
Rail-to-Rail Input and Output
Precision C-Load Op Amp
DESCRIPTION
The RH1499 is a quad, rail-to-rail input and output precision
C-Load™ op amp with a 10MHz gain-bandwidth product
and a 6V/μs slew rate.
The RH1499 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 RH1499 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
RH1499 is guaranteed to add less than 1LSB of error even
in single 3V supply systems.
With 110dB of supply rejection, the RH1499 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.

Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
A heat sink may be required to keep the junction temperature
below this absolute maximum rating when the output is shorted
indefinitely.
Note 3:
Matching parameters are the difference between amplifiers A and
D and between B and C.
Note 4:
Output voltage swings are measured between the output and
power supply rails.
