PCM1792DBG4 Equivalent & Substitute Parts

Part Overview

The PCM1792DBG4 is a 24-bit audio digital-to-analog converter (DAC) manufactured by Texas Instruments, designed for high-resolution audio applications with support for both DSD and PCM data interfaces. This component operates at a 200 kHz sampling rate and features 3 output channels, making it suitable for professional audio equipment and consumer audio systems.

The PCM1792DBG4 has been discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and component procurement. Substitute parts must maintain identical electrical specifications, package compatibility, and operational characteristics to ensure seamless integration into existing designs.

Frequently Asked Questions (FAQ)

Q: Can the PCM1792DB replace the PCM1792DBG4 in existing designs?

A: Yes. The PCM1792DB is electrically and mechanically equivalent to the PCM1792DBG4. All functional parameters, including resolution, sampling rate, channel configuration, data interfaces, power supply requirements, and package specifications are identical. Direct substitution is possible without circuit modification.

Q: Are there differences in packaging between these parts?

A: Both components use the 28-SSOP surface mount package with identical physical dimensions (0.209" width, 5.30mm). The PCM1792DBG4 packaging specification is not detailed in available data, while the PCM1792DB is supplied in tube packaging. This distinction does not affect electrical compatibility or board-level integration.

Q: What is the significance of the product status difference?

A: The PCM1792DBG4 is discontinued at DiGi Electronics, indicating end-of-life status for this specific part number. The PCM1792DB is marked "Not For New Designs," indicating it remains available but is not recommended for new product development. For applications requiring component procurement, the PCM1792DB represents the available alternative from the same manufacturer with identical specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PCM1792DBG4 and PCM1792DB are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What are the critical parameters for substitution verification?

A: Substitution compatibility is determined by: 24-bit resolution, 200 kHz sampling rate, 3-channel configuration, DSD and PCM data interface support, dual analog and digital power supply (3V–3.6V and 5V), 28-SSOP package, and -25°C to 85°C operating temperature range. Any deviation in these parameters indicates incompatibility.
