DESCRIPTIO
The LT^®1809 is a low distortion rail-to-rail input and
output op amp with a 350V/µs slew rate. The amplifier has
a –3dB bandwidth of 320MHz at unity-gain, a gain-band-
width product of 180MHz (A_V ≥ 10) and an 85mA output
current to fit the needs of low voltage, high performance
signal conditioning systems.
The LT1809 has an input range that includes both supply
rails and an output that swings within 20mV of either
supply rail to maximize the signal dynamic range in low
supply applications.
The LT1809 has very low distortion (–90dBc) up to 5MHz
that allows it to be used in high performance data acqui-
sition systems.
The LT1809 maintains its performance for supplies from
2.5V to 12.6V and is specified at 3V, 5V and ±5V supplies.
The inputs can be driven beyond the supplies without
damage or phase reversal of the output.
The LT1809 is available in the 8-pin SO package with the
standard op amp pinout. This device can be used as a plug-
in replacement for many op amps to improve input/output
range and performance.
