Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV320AIC23IPWR is determined by strict equivalence across the following critical parameters:

• Data Interface: I2C and Serial protocols must be supported
• Resolution Support: 16-bit, 20-bit, 24-bit, and 32-bit audio resolution capability
• ADC/DAC Configuration: Dual ADCs and dual DACs required
• Sigma Delta Architecture: Must be present
• Signal Quality: S/N ratio (ADCs/DACs) of 90/100 dB typical and dynamic range of 90/90 dB typical
• Supply Voltage Ranges: Analog supply 2.7V–3.6V and digital supply 1.42V–3.6V
• Package: 28-TSSOP form factor with identical pin pitch and dimensions
• Compliance: ROHS3 compliant, REACH unaffected, MSL Level 1

The substitute part TLV320AIC23IPW meets all specified electrical and mechanical parameters, establishing direct functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the TLV320AIC23IPWR and TLV320AIC23IPW are classified as obsolete products. Selection between these parts should be based on current inventory availability and procurement lead times. Both components maintain identical electrical specifications, mechanical packaging, and regulatory compliance certifications (ROHS3, REACH unaffected). The TLV320AIC23IPW currently shows higher inventory availability (2420 pcs vs. 1214 pcs), which may influence procurement decisions for new production runs or design refreshes. Pin-for-pin compatibility and functional equivalence are confirmed across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Are TLV320AIC23IPWR and TLV320AIC23IPW pin-for-pin compatible?

A: Yes. Both components use the 28-TSSOP package with identical pin assignments, electrical characteristics, and mechanical dimensions. Direct substitution is supported without PCB redesign.

Q: What audio resolutions do these codecs support?

A: Both parts support 16-bit, 20-bit, 24-bit, and 32-bit audio resolution through I2C and serial data interfaces.

Q: Can these parts operate from a single power supply?

A: No. These codecs require separate analog (2.7V–3.6V) and digital (1.42V–3.6V) supply voltages. Dual supply rails must be provided in the application circuit.

Q: Are there any differences in signal quality between the two parts?

A: No. Both parts deliver identical S/N ratios (90 dB for ADCs, 100 dB for DACs) and dynamic range (90 dB for both ADCs and DACs).

Q: What is the moisture sensitivity level for these components?

A: Both parts are rated MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are these parts suitable for new designs?

A: Both parts are classified as obsolete. For new designs, evaluation of current-generation audio codec alternatives from Texas Instruments is recommended to ensure long-term supply availability and access to design support resources.
