Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCM1792DBR is determined by strict equivalence across the following critical parameters:

• Resolution and Sampling Rate: 24-bit resolution at 200 kHz sampling rate
• Channel Configuration: 3-channel audio DAC architecture
• Data Interface Support: DSD and PCM protocol compatibility
• Supply Voltage Compatibility: Dual supply operation (3V ~ 3.6V and 5V)
• Operating Temperature Range: -25°C ~ 85°C
• Package Specification: 28-SSOP surface mount package with 0.209" width (5.30mm)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The PCM1792ADBR meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for substitution.

Parameter Comparison

Engineering Selection Recommendations

The PCM1792ADBR is the direct substitute for the PCM1792DBR. Both devices are manufactured by Texas Instruments and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the PCM1792DBR is obsolete while the PCM1792ADBR is active.

For applications currently using the PCM1792DBR, the PCM1792ADBR provides continued component availability without design modification. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements. The identical 28-SSOP package ensures direct PCB compatibility.
