LT1498/LT1499  
10MHz, 6V/µs, Dual/Quad  
Rail-to-Rail Input and Output  
Precision C-Load Op Amps  
FEATURES  
DESCRIPTION  
The LT®1498/LT1499 are dual/quad, rail-to-rail input and  
output precision C-Load™ op amps with a 10MHz gain-  
bandwidth product and a 6V/μs slew rate.

Gain-Bandwidth Product: 10MHz  
Slew Rate: 6V/μs  
The LT1498/LT1499 are designed to maximize input  
dynamic range by delivering precision performance over  
the full supply voltage. Using a patented technique, both  
input stages of the LT1498/LT1499 are trimmed, one at  
the negative supply and the other at the positive supply.  
Theresultingguaranteedcommonmoderejectionismuch  
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 LT1498/LT1499 are guaranteed to add less  
than 1LSB of error even in single 3V supply systems.  
Low Supply Current per Amplifier: 1.7mA  
Input Offset Current: 65nA Max  
Input Bias Current: 650nA Max  
Open-Loop Gain: 1000V/mV Min  
Low Input Noise Voltage: 12nV/√Hz Typ  
Wide Supply Range: 2.2V to 15V  
Large Output Drive Current: 30mA  
Stable for Capacitive Loads Up to 10,000pF  
Dual in 8-Pin PDIP and SO Package  
Quad in Narrow 14-Pin SO  
With 110dB of supply rejection, the LT1498/LT1499 main-  
tain their performance over a supply range of 2.2V to 36V  
and are specified for 3V, 5V and 15V supplies. The inputs  
canbedrivenbeyondthesupplieswithoutdamageorphase  
reversal of the output. These op amps remain stable while  
driving capacitive loads up to 10,000pF.

features the standard quad op amp configuration and is  
available in a 14-pin plastic SO package. These devices  
can be used as plug-in replacements for many standard  
op amps to improve input/output range and precision.
