PCM1716E Equivalent & Substitute Parts

Part Overview

The PCM1716E is a 24-bit audio DAC (Digital-to-Analog Converter) manufactured by Texas Instruments, designed for audio applications with I2S interface support and 96 kHz sampling rate capability. The device operates from a 5V supply and is housed in a 28-SSOP surface mount package. The PCM1716E is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCM1716E is determined by the following critical parameters: resolution (24-bit minimum), data interface compatibility (I2S or PCM), channel count (2 channels), and surface mount packaging. The substitute parts identified maintain 24-bit resolution and 2-channel configuration while offering enhanced specifications in sampling rate and supply voltage flexibility.

PCM1754DBQ qualifies as a substitute through matching 24-bit resolution, 2-channel architecture, and I2S interface, with the trade-off of reduced package size (16-SSOP versus 28-SSOP) and higher maximum sampling rate (200 kHz). PCM5102APW qualifies through 24-bit resolution support, 2-channel configuration, and PCM interface compatibility, with enhanced sampling rate capability (384 kHz) and flexible supply voltage range (1.65V ~ 3.46V).

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the PCM1716E. PCM1754DBQ is an active product offering direct I2S interface compatibility with the original design, though package size reduction from 28-SSOP to 16-SSOP requires PCB layout modification. PCM5102APW is an active product with extended sampling rate capability and flexible supply voltage operation, though PCM interface substitution for I2S requires protocol conversion consideration in system architecture.

Frequently Asked Questions (FAQ)

Q: Can PCM1754DBQ directly replace PCM1716E in existing designs? A: PCM1754DBQ maintains I2S interface and 24-bit resolution compatibility. However, the package change from 28-SSOP to 16-SSOP requires PCB redesign. Pin configuration differences must be verified against datasheets before implementation.

Q: What is the primary difference between PCM1754DBQ and PCM5102APW? A: PCM1754DBQ uses I2S interface with 200 kHz maximum sampling rate and requires 5V supply. PCM5102APW uses PCM interface with 384 kHz maximum sampling rate and operates from 1.65V to 3.46V supply. Interface protocol differences require system-level evaluation.

Q: Is PCM5102APW suitable for 5V supply applications? A: PCM5102APW operates within the 1.65V to 3.46V supply range, which does not include 5V operation. Direct substitution in 5V-only systems requires voltage regulation or system redesign.

Q: Are all substitute parts available in the same packaging? A: No. PCM1716E uses 28-SSOP, PCM1754DBQ uses 16-SSOP, and PCM5102APW uses 20-TSSOP. Package differences require PCB layout modifications for any substitution.

Q: Do substitute parts maintain the same operating temperature range? A: PCM1754DBQ extends the lower operating temperature to -40°C compared to PCM1716E and PCM5102APW at -25°C. Upper temperature limits remain consistent at 85°C across all three devices.
