CA358 overview

CA358 is a component documented by Intersil Corporation. The PDF description identifies it as "Dual, 1MHz, Operational Amplifiers for Commercial Industrial, and Military Applications October 1999." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details

The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.

  • This transistor action is not destructive and normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than -0.3V.
  • The maximum output current is approximately 40mA independent of the magnitude of V+.
  • Continuous short circuits at V+ > 15V can cause excessive power dissipation and eventual destruction.
  • Supply Voltage V+ = 5V, V- = 0V, Unless Otherwise Specified PARAMETER TEST CONDITIONS TEMP (oC) CA158A CA358A UNITSMIN TYP MAX MIN TYP MAX Input Offset Voltage (Note 6) 25 - 1 2 - 2 3 mV Full - - 4 - - 5 mV Average Input Offset Voltage Drif.
  • The input signal voltage and the input common mode voltage should not be allowed to go negative by more than 0.3V.
  • The positive limit of the common mode voltage range is V+ - 1.5V, but either or both inputs can go to +32V without damage.
  • VO = 1.4V, RS = 0Ω with V+ from 5V to 30V, and over the full input common mode voltage range (0V to V+ - 1.5V).

Topics covered by the datasheet

The document includes sections related to:

  • Features
  • Ordering Information

Engineering review checklist

  • Confirm repetitive reverse voltage, average forward current, surge current and leakage at the intended temperature.
  • Check forward-voltage loss and reverse-recovery behavior at the actual current and switching frequency.
  • Review package thermal resistance, copper area, polarity marking and transient derating before layout release.

Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
