精密測(cè)量
???? Making precision measurements of any kind can be extremely difficult. When designing precision instrumentation that depends on sensors, engineers are challenged with achieving the highest accuracy possible. Sensor characteristics present design difficulties that can be compounded by errors from amplifiers due to voltage offset temperature drift and input bias current.
National's new additions to its amplifier family provide advanced levels of precision. The new op amps offer ultra-low input bias current, extremely low offset voltage temperature drift, and low input current noise. In addition, the excellent performance-to-power ratios of the new amplifiers place them in the energy-efficient PowerWise? line of products brought to you only from National.
