Substitute Part Grouping Explanation

Substitution of the OPA847IDG4 is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is the base product number OPA847, which defines the core amplifier topology and performance characteristics.

The OPA847IDG4 and its substitute OPA847ID share identical electrical specifications:

• Voltage feedback amplifier architecture with single circuit configuration
• Slew rate of 950 V/µs
• Gain bandwidth product of 3.9 GHz
• Input bias current of 19 µA
• Input offset voltage of 100 µV
• Supply current of 18.1 mA
• Output current capability of 100 mA per channel
• Supply voltage range from 5 V to 12 V
• Operating temperature range of -40°C to 85°C
• 8-SOIC surface mount package with identical physical dimensions

The distinction between these parts lies in product status and packaging format. The OPA847IDG4 is obsolete, while the OPA847ID maintains active product status. Both devices are ROHS3 compliant and carry identical moisture sensitivity ratings.
