Information furnished by Linear Technology Corporation is believed to be accurate and reliable.

However, no responsibility is assumed for its use. Linear Technology Corporation makes no represen-

tation that the interconnection of its circuits as described herein will not infringe on existing patent rights.

The LT

features a 325MHz gain bandwidth product, a 140V/

µs

slew rate and a 85mA output current to fit the need for low

voltage, high performance signal conditioning systems.

The LT1806 has a very low distortion of – 80dBc at 5MHz,

a low input referred noise voltage of 3.5nV/

√Hz and a

maximum offset voltage of 550

µV that allows it to be used

in high performance data acquisition systems.

The LT1806 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 LT1806 maintains its performance for supplies from

2.5V to 12V 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 LT1806 is available in an 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.
