TLV5618AIPG4 Equivalent & Substitute Parts

Part Overview

The TLV5618AIPG4 is a 12-bit digital-to-analog converter (DAC) with dual output channels, designed for data acquisition applications requiring precision voltage output. This device features SPI interface compatibility, external reference capability, and operates across dual supply voltage ranges (2.7V to 3.3V and 5V). The TLV5618AIPG4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV5618AIPG4 is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit conversion
• Channel count: Dual D/A converters
• Interface protocol: SPI serial communication
• Output configuration: Buffered voltage output
• Reference input: External reference requirement
• Supply voltage ranges: 2.7V to 3.3V and 5V dual supply capability
• Linearity specifications: INL/DNL performance (±2 LSB / ±0.5 LSB)
• Package form factor: 8-DIP through-hole mounting
• Temperature range: -40°C to 85°C industrial grade

The TLV5618AIP meets all electrical and mechanical substitution criteria. The primary distinction is product status and packaging format.
