PCM1802DBG4 Equivalent & Substitute Parts

Part Overview

The PCM1802DBG4 is a 24-bit audio analog-to-digital converter (ADC) manufactured by Texas Instruments, designed for high-resolution audio acquisition applications. It features dual-channel audio conversion at 96 kHz sampling rate with serial data interface output. The PCM1802DBG4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCM1802DBG4 is based on strict equivalence across the following critical parameters:

• Resolution and Sampling Rate: 24-bit resolution at 96 kHz sampling rate
• Channel Configuration: Dual-channel audio input
• Data Interface: Serial output protocol
• Supply Voltage Range: Dual supply rails (2.7V–3.6V and 4.5V–5.5V)
• Operating Temperature Range: −40°C to +85°C
• Package Type: 20-SSOP surface mount package with identical physical dimensions
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The PCM1802DB meets all these criteria and is identified as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The PCM1802DB is the direct functional equivalent of the PCM1802DBG4. Both parts share identical electrical specifications, package geometry, and compliance certifications. The primary distinction is product status: the PCM1802DBG4 is discontinued, while the PCM1802DB remains in active production and is available in higher inventory quantities (1205 units versus 743 units).

For new designs or procurement requiring the PCM1802DBG4 specifications, the PCM1802DB is the appropriate selection. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The packaging difference (tube versus unspecified for the main part) does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the PCM1802DB be used as a direct replacement for the PCM1802DBG4?

A: Yes. Both parts are identical in electrical performance, pin configuration, package dimensions, and operating specifications. The PCM1802DB is the manufacturer-recommended substitute.

Q: Are there any differences in pin configuration or signal timing between these parts?

A: No. Both parts use the 20-SSOP package with identical pinout and serial interface protocol. No circuit modifications are required.

Q: What is the difference between the packaging designations?

A: The PCM1802DB is supplied in tube packaging, while the PCM1802DBG4 packaging type was not specified in the original documentation. This is a distribution format difference only and does not affect component functionality or performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PCM1802DBG4 and PCM1802DB are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Is the PCM1802DB available for immediate procurement?

A: Yes. The PCM1802DB is in active production status with 1205 units in stock, compared to the discontinued PCM1802DBG4.
