Application Scenarios & Design Considerations

80V, Low- or High-side, High-Speed, Voltage Out Current Shunt Monitor with Comparator and Reference 8-SOIC -40 to 125

Alternative Part Number

  • AD8210ARZ --: High-side current sense amplifier with similar gain and bandwidth, widely available and pin-compatible in function.
  • LT6105IMS8 --: Precision current sense amplifier with comparable common-mode range and accuracy, suitable drop-in functional replacement.
  • MAX4080TASA --: High-side current sense amplifier with similar voltage range and gain options, good alternative when INA201 is unavailable.

Application Scenarios & Design Considerations

80V, Low- or High-side, High-Speed, Voltage Out Current Shunt Monitor with Comparator and Reference 8-SOIC -40 to 125

Alternative Part Number

  • INA282AIDR --: Same current-sense amplifier family from TI (which absorbed Burr-Brown), similar voltage-output architecture and SOIC-8 package, good drop-in with wider common-mode range.
  • INA195AIDBVR --: Voltage-output current shunt monitor in SOT-23-5 with comparable gain and bandwidth, suitable when board space is limited and pinout can be adapted.
  • AD8210YRZ --: Alternative high-side current sense amplifier from a different vendor with similar function and SOIC-8 footprint, useful as a second-source option.
