DESCRIPTION
The INA120 is a precision instrumentation amplifier
ideal for accurate signal acquisition. It combines pre-
cision, protected-input operational amplifiers, laser-
trimmed gain-setting resistors, and a high common-
mode rejection difference amplifier on a single chip.
Simple pin-strapped connections set precise gains of 1,
10, 100 or 1000. External resistors can be used to set
any gain from one to 5000. Gains can be digitally
selected with an external multiplexer. Gain-sense con-
nections on the INA120 maintain accuracy when using
multiplexer or gain-switching circuitry. Low power
dissipation and careful on-chip thermal management
reduce warm-up drift and assure excellent long-term
stability.
The INA120 is available in both plastic and ceramic
18-pin DIP packages, specified for the industrial tem-
perature range.
