Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC5620ING4 is determined by strict equivalence across the following critical parameters:

• Resolution: 8-bit conversion capability
• Channel Count: Four independent D/A converters
• Output Configuration: Voltage output with buffering
• Interface Protocol: SPI serial communication
• Reference Architecture: External voltage reference
• Supply Voltage: 5V analog and digital supplies
• Linearity Specifications: INL/DNL performance within ±1 LSB and ±0.9 LSB
• Package Form Factor: 14-DIP through-hole mounting
• Temperature Operating Range: -40°C to 85°C

The TLC5620IN meets all substitution criteria as a direct functional equivalent with identical electrical specifications and package configuration.
