Key Parameters

Substitute Part Grouping Explanation

Substitution of the INA4290A2IRGVT is determined by electrical and mechanical parameter equivalence across the following critical criteria:

Electrical Parameters:

• Amplifier type (Current Sense)
• Number of independent circuits (4 channels)
• Slew rate (2 V/µs)
• Gain bandwidth product (1.1 MHz)
• Input bias current (20 µA)
• Input offset voltage (6 µV)
• Supply current per channel (1.25 mA)
• Supply voltage range (2.7 V to 20 V)
• Operating temperature range (-40°C to 125°C)

Mechanical Parameters:

• Package type (16-VQFN with exposed pad, 4x4 mm footprint)
• Mounting technology (Surface Mount)
• Moisture sensitivity classification (MSL 1)

The INA4290A2IRGVR is identified as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction between these parts is product status and packaging designation (tape & reel format remains consistent).
