DAC7574IDGSG4 Equivalent & Substitute Parts

Part Overview

The DAC7574IDGSG4 is a 12-bit digital-to-analog converter featuring 4 independent D/A channels with buffered voltage output. This component is designed for data acquisition applications requiring precision analog signal generation from digital inputs. The device operates across a wide supply voltage range of 2.7V to 5.5V for both analog and digital supplies, making it suitable for mixed-signal system integration.

The DAC7574IDGSG4 is currently discontinued at DiGi Electronics. Locating equivalent or substitute components is necessary to maintain design continuity and ensure project timelines are not compromised. The substitute part identified maintains full electrical and mechanical compatibility with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC7574IDGSG4 is determined by strict equivalence across the following critical parameters:

• 12-bit resolution with 4 independent D/A converter channels
• Buffered voltage output configuration
• I2C digital interface protocol
• Identical supply voltage ranges (2.7V ~ 5.5V for both analog and digital)
• Matching INL/DNL specifications (±8 LSB max, ±1 LSB max)
• 10µs settling time performance
• Identical package footprint (10-TFSOP, 10-MSOP, 0.118" width, 3.00mm)
• Surface mount mounting type
• Operating temperature range of -40°C ~ 105°C

The substitute part DAC7574IDGS meets all these criteria and is electrically and mechanically interchangeable with the original component.

Parameter Comparison
