Substitute Part Grouping Explanation

Substitution of the TLV272IDRG4 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Dual-channel general-purpose amplifier configuration with identical slew rate (2.6 V/µs), gain bandwidth product (3 MHz), input bias current (1 pA), input offset voltage (500 µV), supply current (550 µA per dual channels), output current capability (8 mA per channel), and supply voltage range (2.7 V to 16 V).

Mechanical & Package Specifications: Surface mount 8-SOIC package with identical physical dimensions (0.154" width, 3.90mm).

Environmental & Compliance Specifications: Operating temperature range (-40°C to 125°C), ROHS3 compliance, MSL Level 1, and REACH unaffected status.

The substitute part TLV272IDR maintains complete electrical, mechanical, and compliance equivalence with the obsolete TLV272IDRG4, differing only in product status (active versus obsolete).
