RH1498M

The RH1498 is a dual, rail-to-rail input and output precision C-LoadTM op amp with a 10MHz gain-bandwidth product and a 6V/ms 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-torail input op amps. When used as a unity-gain buffer in ront 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 inhouse Class S flow to yield circuits usable in stringent military and space applications.
