DESCRIPTION
The INA104 is a high accuracy, multistage, inte-
grated-circuit instrumentation amplifier designed for
signal conditioning requirements where very high per-
formance is desired.
A multiamplifier, monolithic design, which uses Burr-
Brown’s ultra-low drift, low-noise technology, pro-
vides the highest performance with maximum versatil-
ity at the lowest cost and makes the INA104 ideal for
even high volume applications.
Burr-Brown’s compatible thin-film resistors and laser-
trimming techniques are used for minimizing offset
voltage and temperature drift. This advanced tech-
nique also maximizes common-mode rejection and
gain accuracy.
The INA104 also contains a fourth operational ampli-
fier, specified separately, which can conveniently be
used for some important applications such as single
capacitor active low-pass filtering, easy output level
shifting, common-mode voltage active guard drive,
and increased gain (x 10,000 and greater).
