DESCRIPTION  
FEATURES  
The LT®1498/LT1499 are dual/quad, rail-to-rail input and  
output precision C-LoadTM op amps with a 10MHz gain-  
bandwidth product and a 6V/µs slew rate.  
Rail-to-Rail Input and Output  
475µV Max VOS from V+ to V–  
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  
inputstagesoftheLT1498/LT1499aretrimmed,oneatthe  
negative supply and the other at the positive supply. The  
resulting guaranteed common mode rejection is much  
betterthanotherrail-to-railinputopamps. Whenusedasa  
unity-gain buffer in front of single supply 12-bit A-to-D  
converters,theLT1498/LT1499areguaranteedtoaddless  
than 1LSB of error even in single 3V supply systems.  
Low Supply Current per Amplifier: 1.7mA  
Input Offset Current: 50nA Max  
Input Bias Current: 500nA 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  
With110dBofsupplyrejection, theLT1498/LT1499main-  
tain their performance over a supply range of 2.2V to 36V  
and are specified for 3V, 5V and±15V supplies. 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.

APPLICATIONS  
Driving A-to-D Converters  
Active Filters  
Rail-to-Rail Buffer Amplifiers  
Low Voltage Signal Processing  
The LT1498 is available with the standard dual op amp  
configurationin8-pinPDIPandSOpackaging.TheLT1499  
features the standard quad op amp configuration and is  
availableina14-pinplasticSOpackage. Thesedevicescan  
be used as plug-in replacements for many standard op  
amps to improve input/output range and precision.
