Rail-to-Rail Input and Output
The LT®1498/LT1499 are dual/quad, rail-to-rail input and n
475μV Max VOS from V+ to V–
output precision C-Load™ op amps with a 10MHz gain- n
Gain-Bandwidth Product: 10MHz
bandwidth product and a 6V/μs slew rate. n
Slew Rate: 6V/μs
The LT1498/LT1499 are designed to maximize input n
Low Supply Current per Amplifi er: 1.7mA
dynamic range by delivering precision performance over n Input Offset Current: 65nA Max the full supply voltage. Using a patented technique, both n Input Bias Current: 650nA Max input stages of the LT1498/LT1499 are trimmed, one at n Open-Loop Gain: 1000V/mV Min the negative supply and the other at the positive supply. n Low Input Noise Voltage: 12nV/√Hz Typ The resulting guaranteed common mode rejection is much n Wide Supply Range: 2.2V to ±15V better than other rail-to-rail input op amps. When used as n Large Output Drive Current: 30mA a unity-gain buffer in front of single supply 12-bit A-to-D n Stable for Capacitive Loads Up to 10,000pF converters, the LT1498/LT1499 are guaranteed to add less n Dual in 8-Pin PDIP and SO Package than 1LSB of error even in single 3V supply systems. n 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
