LT1498/LT1499 10MHz, 6V/s, Dual/Quad Rail-to-Rail Input and Output Precision C-Load Op Amps FEATURES DESCRIPTION n Rail-to-Rail Input and Output The LT 1498/LT1499 are dual/quad, rail-to-rail input and + n 475V Max V from V to V output precision C-Load op amps with a 10MHz gain- OS n Gain-Bandwidth Product: 10MHz bandwidth product and a 6V/s slew rate. n Slew Rate: 6V/s The LT1498/LT1499 are designed to maximize input n Low Supply Current per Ampli 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 APPLICATIONS and are speci ed for 3V, 5V and 15V supplies. The inputs n can be driven beyond the supplies without damage or phase Driving A-to-D Converters n reversal of the output. These op amps remain stable while Active Filters n driving capacitive loads up to 10,000pF. Rail-to-Rail Buffer Ampli ers n Low Voltage Signal Processing The LT1498 is available with the standard dual op amp n Battery-Powered Systems con guration in 8-pin PDIP and SO packaging.
