Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC5620CDG4 is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Count: 8-bit resolution with 4 independent DAC channels
• Output Configuration: Voltage-buffered output type
• Communication Protocol: SPI digital interface
• Supply Voltage Requirements: 5V analog and 5V digital supplies
• Performance Specifications: Settling time of 10µs (Typ) and INL/DNL specifications of ±1 (Max) and ±0.9 (Max) LSB
• Package Compatibility: 14-SOIC surface mount package with 0.154" (3.90mm) width
• Environmental Compliance: ROHS3 compliance and MSL Level 1 rating

The TLC5620CD meets all these criteria and serves as a direct substitute. The primary distinction between the main part and substitute is product status and packaging format, with the TLC5620CD currently active in production and available in tube packaging.
