Substitute Part Grouping Explanation

Substitution of the INA4290A3IRGVT is determined by electrical and mechanical parameter equivalence. The primary substitute part, INA4290A3IRGVR, maintains identical specifications across all critical performance parameters: amplifier type, circuit count, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, supply voltage range, operating temperature range, and package configuration. Both parts are manufactured by Texas Instruments and utilize the same 16-VQFN Exposed Pad package with identical pinout and footprint compatibility.

The substitution is valid based on the following key parameters:

• Amplifier Type: Current Sense (identical)
• Number of Circuits: 4 (identical)
• Slew Rate: 2 V/µs (identical)
• Gain Bandwidth Product: 1.1 MHz (identical)
• Current - Input Bias: 20 µA (identical)
• Voltage - Input Offset: 6 µV (identical)
• Current - Supply: 1.25 mA (x4 Channels) (identical)
• Voltage - Supply Span: 2.7 V to 20 V (identical)
• Operating Temperature: -40°C ~ 125°C (identical)
• Package / Case: 16-VQFN Exposed Pad (4x4) (identical)
• Mounting Type: Surface Mount (identical)

Parameter Comparison

Engineering Selection Recommendations

The INA4290A3IRGVR is the direct substitute for the INA4290A3IRGVT. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications.
