INA146
DESCRIPTION
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 ex-
tends beyond both supply rails, making the INA146
well-suited for both single and dual supply applica-
tions.
On-chip precision resistors are laser-trimmed to achieve
accurate gain and high common-mode rejection. Ex-
cellent TCR tracking of these resistors assures contin-
ued 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 affect-
ing the common-mode input range.
The INA146 is available in the SO-8 surface-mount
package specified for the extended industrial tempera-
ture range, –40
°
C to +85
°
C.
