Substitute Part Grouping Explanation

Substitution of the obsolete LT6375IDF is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for amplifier topology, circuit count, output characteristics, frequency response, supply voltage range, and thermal operating window. Package compatibility is mandatory, requiring the same 14-DFN (4x4) surface mount footprint and pin configuration.

The substitution logic is based on the following critical parameters:

• Amplifier Type: Differential (single circuit)
• Output Type: Rail-to-Rail operation
• Slew Rate: 2.4V/µs
• -3dB Bandwidth: 575 kHz
• Voltage - Input Offset: 120 µV
• Supply Current: 350µA
• Output Current per Channel: 28 mA
• Supply Voltage Range: 3V to 50V
• Operating Temperature: -40°C to 85°C
• Package: 14-DFN (4x4) with exposed pad
