RH1498M - 10MHz, 6V/µs, Dual Rail-to-Rail Input and Output Precision C-Load Op Amp

RH1498M
10MHz, 6V/µs, Dual
Rail-to-Rail Input and Output
Precision C-Load Op Amp
DESCRIPTION
ABSOLUTE MAXIMUM RATINGS
The RH1498M 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.
(Note 1)
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-torail 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
5V supply systems.
Total Supply Voltage (V + to V–)................................ 36V
Input Current........................................................ ±10mA
Output Short-Circuit Duration (Note 2)......... Continuous
Operating Temperature Range............... – 55°C to 125°C
Specified Temperature Range................. – 55°C to 125°C
Junction Temperature .......................................... 150°C
Storage Temperature Range....................– 65°C to 150°C
Lead Temperature (Soldering, 10 sec)................... 300°C
With 110dB of supply rejection, the RH1498 maintains its
performance over a supply range of 4.5V 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 inhouse 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
