PCM1602Y/2K

ADCs/DACs - Special Purpose Overview

The PCM1602Y/2K 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. It accepts 16-, 18-, 20-, and 24-bit audio data in Standard, I2S, or Left-Justified formats via a 5-wire serial interface.

ADCs/DACs - Special Purpose Feature Summary

• Six independent 24-bit DACs with typical dynamic range of 100 dB and THD+N of 0.003% at 44.1 kHz
• Dual-supply design: 5 V analog (VCC) and 3.3 V digital (VDD) with 5-V tolerant logic inputs
• User-programmable via 4-wire serial control port for digital attenuation, soft mute, and filter rolloff selection
• Supports system clocks from 128 fS to 768 fS with selectable sharp or slow digital filter rolloff

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/2K' against the manufacturer's current datasheet to confirm packaging details and availability status. Ensure that the required voltage levels match the specified 5 V analog and 3.3 V digital supplies. Confirm that the LQFP-48 package dimensions align with the target PCB layout constraints before finalizing procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a multi-channel high-resolution audio output is required within a single IC. The PCM1602Y variant offers a typical dynamic range of 100 dB, whereas the PCM1602KY variant provides 105 dB; verify if the higher performance variant is needed. Ensure the application can accommodate the dual power supply requirement and the specific serial interface timing constraints for BCK and LRCK.

ADCs/DACs - Special Purpose Part Context

The PCM1602 belongs to Texas Instruments' family of high-performance audio DACs designed for multichannel applications. It is part of the SBAS163A series documentation. The '/2K' suffix typically indicates tape-and-reel packaging containing 2000 units, consistent with other TI components in similar packages. This device serves as a core conversion element in complex audio signal chains requiring low jitter tolerance and high linearity.
