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

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 5V supply systems.

With 110dB of supply rejection, the RH1499 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 our in-house Class S flow to yield circuits usable in stringent military and space applications.
