PCM1702U-JE6

ADCs/DACs - Special Purpose Overview

The PCM1702U-JE6 is a BiCMOS advanced sign magnitude 20-bit digital-to-analog converter manufactured by Texas Instruments. It features ultra-low distortion of –96dB max THD+N and a typical signal-to-noise ratio of 120dB using the A-weighted method. The device operates with a ±5V supply, consuming 150mW typ power. It supports industry-standard serial input formats with a maximum clock frequency of 20MHz and delivers a fast settling current output of ±1.2mA in 200ns. The component is housed in a 20-pin SOP package and functions within an operating temperature range of –25°C to +85°C.

ADCs/DACs - Special Purpose Feature Summary

• Advanced sign magnitude architecture eliminates glitches around bipolar zero for near-ideal low-level operation
• Ultra-low total harmonic distortion plus noise (–96dB max) without external adjustment
• Fast settling current output of ±1.2mA with 200ns typical settling time
• Capable of 16x oversampling rates with industry standard serial input format

ADCs/DACs - Special Purpose Applications

• High-end consumer digital audio applications
• Professional digital audio systems
• Very low distortion frequency synthesis

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix JE6 against the manufacturer's latest documentation to confirm package type and grade markings. Confirm availability status as product lifecycles may change. Ensure design-in compliance with absolute maximum ratings including supply voltage limits of ±6.5VDC and soldering temperature constraints.

ADCs/DACs - Special Purpose Selection Notes

Select this component when high-resolution 20-bit conversion is required with minimal external filtering. The integrated reference and glitch-free output simplify circuit design compared to other DACs. Ensure the host system provides a stable ±5V supply and a serial clock rate up to 20MHz. Consider the 20-pin SOP footprint for PCB layout constraints.

ADCs/DACs - Special Purpose Part Context

The PCM1702 series includes variants such as PCM1702P, PCM1702U, PCM1702U-J, and PCM1702U-K. The U designation indicates a 20-pin Plastic SOP package, while J denotes a specific performance grade marked with a white dot by pin 10. The /2K suffix typically indicates tape and reel packaging quantity, though verification with official datasheets is required for specific lot configurations.
