DESCRIPTION
The INA101 is a high accuracy instrumentation ampli-
fier designed for low-level signal amplification and
general purpose data acquisition. Three precision op
amps and laser-trimmed metal film resistors are inte-
grated on a single monolithic integrated circuit.
The INA101 is packaged in TO-100 metal, 14-pin
plastic and ceramic DIP, and SOL-16 surface-mount
packages. Commercial, industrial and military tem-
perature range models are available.
