INA326:精密低漂移 CMOS 仪器放大器

备选器件推荐
  • INA327 - ?The INA327 has shutdown and package MSOP-10
  • INA321 - ?500?V VOS, 0.5pA IB, 94dB CMRR, 60?A IQ, rail-to-rail output
  • INA337 - ?Precision, 0.4?V/°C drift, specified –40°C to +125°C
  • INA122 - ?250?V VOS, 10nA IB, 85?A IQ, rail-to-rail output, 3?V/°C drift

The INA326 and INA327 (with shutdown) are high-performance, low-cost, precision instrumentation amplifiers with rail-to-rail input and output. They are true single-supply instrumentation amplifiers with very low DC errors and input common-mode ranges that extends beyond the positive and negative rails. These features make them suitable for applications ranging from general-purpose to high-accuracy.

Excellent long-term stability and very low 1/f noise assure low offset voltage and drift throughout the life of the product.

The INA326 (without shutdown) comes in the MSOP-8 package. The INA327 (with shutdown) is offered in an MSOP-10. Both are specified over the industrial temperature range, –40°C to +85°C, with operation from –40°C to +125°C.
