PCM1600Y

ADCs/DACs - Special Purpose Overview

The PCM1600Y is a CMOS monolithic integrated circuit featuring six 24-bit audio digital-to-analog converters (DACs) in a 48-lead LQFP package. Utilizing enhanced multi-level delta-sigma architecture with 4th-order noise shaping, it supports sampling rates from 10kHz to 100kHz and accepts 16- to 24-bit audio data via Standard, I2S, or Left-Justified formats. The device operates on dual supplies (+5V analog, +3.3V digital) with 5V-tolerant logic inputs. Typical dynamic performance includes a 105dB dynamic range and 0.0018% THD+N at 44.1kHz.

ADCs/DACs - Special Purpose Feature Summary

• Six 24-bit DAC channels with 105dB typical dynamic range and 104dB SNR
• Supports 16, 18, 20, and 24-bit audio data with Standard, I2S, and Left-Justified formats
• User-programmable digital attenuation (0dB to -63dB), soft mute, and de-emphasis
• Dual supply operation: +5V analog and +3.3V digital with 5V tolerant inputs

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 ordering suffix when sourcing components. The standard PCM1600Y is supplied in a 250-piece tray, while the PCM1600Y/2K variant is provided in tape and reel packaging containing 2000 devices per reel. Confirm package type and quantity requirements against the datasheet specifications before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select the PCM1600Y for applications requiring six-channel high-resolution audio conversion. Ensure the system clock frequency matches the supported multiples of the sampling rate (256fs to 768fs). Verify that the host controller can interface with the 4-wire serial control port for register programming and that the power supply rails align with the specified +5V and +3.3V requirements.

ADCs/DACs - Special Purpose Part Context

The PCM1600Y belongs to the PCM1600 family, which shares the same die and electrical characteristics as the PCM1601. The primary distinction between these models is the physical package; the PCM1600 utilizes an LQFP-48 package, whereas the PCM1601 uses an MQFP-48 package. Both are designed for multi-channel audio processing.

ADCs/DACs - Special Purpose Replacement Considerations

The PCM1601 is electrically identical to the PCM1600 but utilizes an MQFP-48 package instead of the LQFP-48. Substitution requires verifying pin compatibility and mechanical fit within the target enclosure.
