DESCRIPTIO
N
U
The LT
1492/LT1493 are dual/quad, low power, single sup-
ply precision op amps with 5MHz gain-bandwidth product,
3V/
μ
s slew rate and only 450
μ
A of quiescent supply current
per amplifier.
With a maximum input offset voltage of only 180
μ
V, the
LT1492/LT1493 eliminate trims in most systems while pro-
viding high frequency performance not usually found in low
power single supply amplifiers.
The LT1492/LT1493 will operate on any supply greater than
2.5V and less than 36V total, and are specified on single 3.3V,
single 5V and
±
15V supplies. Even with their low quiescent
supply current the minimum output drive is 20mA, ideal for
driving low impedance loads.
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.
For applications requiring faster precision single supply
amplifiers, see the 14MHz, 7V/
μ
s LT1211/LT1212, the
28MHz, 12V/
μ
s LT1213/LT1214 or the 23MHz, 50V/

LT1215/LT1216.
