FEATURES  
DESCRIPTION  
The LT®1492/LT1493 are dual/quad, low power, single sup-  
ply precision op amps with 5MHz gain-bandwidth product,  
3V/µs slew rate and only 450µA of quiescent supply current  
per amplifier.  
Gain-Bandwidth Product: 5MHz Typ  
Slew Rate: 3V/µs Typ  
Low Supply Current per Amplifier: 0.55mA Max  
Input Offset Voltage: 180µV Max  
Input Offset Voltage Drift: 3µV/°C Max  
With a maximum input offset voltage of only 180µV, the  
LT1492/LT1493 eliminate trims in most systems while pro-  
viding high frequency performance not usually found in low  
power single supply amplifiers.  
Input Offset Current: 20nA Max  
Input Bias Current: 100nA Max  
Open-Loop Gain: 1500V/mV Min (VS = ±15V)  
Low Input Noise Voltage: 16.5nV/Hz  
The LT1492/LT1493 will operate on any supply greater than  
2.5Vandlessthan36Vtotal, andarespecifiedonsingle3.3V,  
single 5V and ±15V supplies. Even with their low quiescent  
supply current the minimum output drive is 20mA, ideal for  
driving low impedance loads.  
Low Input Noise Current: 0.14pA/Hz  
Large Output Drive Current: 20mA Min  
Single Supply Operation  
Input Voltage Range Includes Ground  
Output Swings to Ground While Sinking Current  
Wide Supply Voltage Range: 2.5V to 36V  
The inputs can be driven beyond the supplies without  
damage or phase reversal of the output. The low operating  
voltage and wide input and output range make the LT1492/  
LT1493 amplifiers ideal for battery-powered applications.  
Specified on 3.3V, 5V and ±15V  
Dual in 8-Pin PDIP and SO Package  
Quad in a Narrow 16-Pin SO Package  
For applications requiring faster precision single supply  
amplifiers, see the 14MHz, 7V/µs LT1211/LT1212, the  
28MHz, 12V/µs LT1213/LT1214 or the 23MHz, 50V/µs  
LT1215/LT1216.
