Descripción de INA146
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 an excellent choice 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 provides continued high precision over temperature.
A 10:1 difference amplifier provides 0.1 V/V gain when the output amplifier is used as a unity-gain buffer. In this configuration, input voltages up to ±100 V can be measured. Gains greater than 0.1 V/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.
