PCM1602Y

ADCs/DACs - Special Purpose Overview

The PCM1602Y is a CMOS monolithic integrated circuit featuring six 24-bit audio digital-to-analog converters (DACs) in an LQFP-48 package. It utilizes an enhanced multilevel delta-sigma architecture with fourth-order noise shaping and 8-level amplitude quantization. The device supports dual-supply operation with a 5-V analog supply (VCC) and a 3.3-V digital supply (VDD). Channels 1 and 2 support sampling frequencies up to 200 kHz, while channels 3 through 6 support up to 100 kHz. Typical dynamic performance includes a 100 dB dynamic range and 100 dB SNR at 44.1 kHz for the PCM1602Y variant.

ADCs/DACs - Special Purpose Feature Summary

• Six-channel 24-bit resolution with enhanced multilevel delta-sigma modulation
• Dual-supply operation: 5 V analog (VCC) and 3.3 V digital (VDD)
• Sampling rates up to 200 kHz for channels 1/2 and 100 kHz for channels 3–6
• Supports Standard, I²S, and Left-Justified data formats with 16-, 18-, 20-, or 24-bit word lengths

ADCs/DACs - Special Purpose Applications

• Integrated A/V receivers
• DVD movie and audio players
• HDTV receivers
• Car audio systems
• Digital audio workstations

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's current production status, as datasheets indicate variants like PCM1602KY exist with different performance specifications. Confirm that the LQFP-48 package availability aligns with current manufacturing schedules. Ensure the source document explicitly lists the PCM1602Y part number to distinguish it from other family members with differing electrical characteristics.

ADCs/DACs - Special Purpose Selection Notes

Select the PCM1602Y when a 100 dB typical dynamic range and SNR are sufficient for the application. If higher performance metrics such as 105 dB dynamic range are required, the PCM1602KY variant must be considered instead. Ensure the system design accommodates the dual-supply requirement of 5 V for analog circuits and 3.3 V for digital logic inputs.

ADCs/DACs - Special Purpose Part Context

The PCM1602 belongs to Texas Instruments' line of high-performance audio DACs utilizing enhanced multilevel delta-sigma technology. This architecture provides excellent signal-to-noise performance and high tolerance to clock jitter. The device is designed for multichannel audio applications requiring precise digital-to-analog conversion with flexible serial interface options.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1602KY is a verified alternative within the same family offering improved dynamic performance (105 dB typical). Verify if the pinout and register compatibility remain identical between the Y and KY variants before substitution.
