The INA146 is a precision difference amplifier that
can be used to accurately attenuate high differential
voltages and reject high common-mode voltages for
compatibility with common signal processing voltage
levels. High-voltage capability also affords inherent
input protection. The input common-mode range extends
beyond both supply rails, making the INA146
well-suited for both single and dual supply applications.
On-chip precision resistors are laser-trimmed to achieve
accurate gain and high common-mode rejection. Excellent
TCR tracking of these resistors assures continued
high precision over temperature.
A 10:1 difference amplifier provides 0.1V/V gain
when the output amplifier is used as a unity-gain
buffer. In this configuration, input voltages up to
±100V can be measured. Gains greater than 0.1V/V
can be set with an external resistor pair without affecting
the common-mode input range.
The INA146 is available in the SO-8 surface-mount
package specified for the extended industrial temperature
range, –40°C to +85°C.
