PCM1716E - 24-Bit 96 kHz Stereo Audio DAC | Texas Instruments
MPN: PCM1716E ✗ Cuối đờiPCM1716E Tóm tắt
A digital-to-analog converter, or DAC, is a signal-conversion IC that transforms digital audio samples into left- and right-channel analog voltage signals. The PCM1716E belongs to the delta-sigma DAC family, a CMOS architecture that uses multi-level noise shaping and digital filtering to produce an analog output suitable for audio amplifiers and line-output stages. Its stereo output architecture supports simultaneous left and right channels from one component.
The PCM1716E provides 24-bit digital resolution and a sampling frequency range of 16 kHz to 96 kHz. The verified manufacturer description identifies support for standard, I2S, and left-justified data formats, giving designers flexibility across common audio source formats. Digital de-emphasis and independent left and right digital attenuation are also identified as device features, allowing software or system-level control of playback behavior.
The converter architecture separates digital signal processing from analog output generation. Its digital interface accepts the bit clock, left-right clock, and serial data signals, while the analog section produces the stereo output. Independent channel attenuation is particularly useful in dual-mono equipment or systems that need separate level management for the two output channels. The CMOS implementation also aligns with modern low-power audio product design requirements.
Typical applications include CD and DVD player analog output stages, digital audio amplifiers, home-theater receivers, active speakers, USB or network audio products, and compact digital audio equipment. For each application, the converter must be followed by an appropriate analog output stage and output filtering network, while the digital source must provide compatible clocking and data timing.
When designing a PCB around the PCM1716E, verify the complete pin assignment and reference layout against the manufacturer datasheet before routing power, clocks, data, and analog outputs. Decoupling should be placed close to the supply pins, analog and digital return paths should be managed carefully, and the output network should preserve the converter's intended signal integrity. The available evidence does not provide the complete pin names, exact electrical limits, or a verified price ladder.
This page consolidates the verified PCM1716E format, resolution, sampling-rate, interface, package, sourcing, and cross-reference information, while clearly separating unavailable electrical details from confirmed manufacturer features. It also provides application guidance, design notes, and a strict review of available drop-in replacement evidence.

Ứng dụng tiêu biểu
PCM1716E phù hợp cho 6 Áp dụngs: CD Player Analog Output, Home-Theater Receiver, Digital Audio Active Speaker, USB and Network Audio Product, Professional Audio Monitor Controller, Digital-Audio Interface and Capture Card.
CD Player Analog Output
PCM1716E fits a CD-player output stage because it provides 24-bit resolution, supports sampling rates through 96 kHz, and accepts standard, I2S, or left-justified digital audio data. The digital transport supplies BCKIN, LRCIN, and DIN, while the converter produces left and right analog channels for the selected output amplifier. Independent channel attenuation can simplify balancing the two output levels. The design should follow the manufacturer application circuit for analog filtering, grounding, and output loading because those values are not included in the supplied excerpts.
Được đề xuất
Home-Theater Receiver
PCM1716E is suitable for a home-theater stereo output channel because its 24-bit delta-sigma architecture operates from 16 kHz to 96 kHz and provides independent left and right attenuation. The receiver’s audio processor can drive BCKIN, LRCIN, and DIN using a compatible serial format. The converter then feeds an analog line stage for routing into the amplifier. A major engineering benefit is the familiar 28-SSOP footprint, although thermal limits, analog output loading, and clock-jitter effects must be checked against the full manufacturer datasheet.
Được đề xuất
Digital Audio Active Speaker
PCM1716E can serve as the DAC stage of a compact digital active speaker when the source supplies a compatible digital audio stream. Its support for 24-bit data at rates up to 96 kHz preserves source resolution, while independent channel attenuation allows separate left and right gain adjustment before the power amplifier. The 28-SSOP package helps minimize board area, but the converter still needs adequate decoupling, clean references, and the manufacturer-specified analog output network to achieve usable signal quality.
Được đề xuất
USB and Network Audio Product
PCM1716E is applicable to USB- or network-audio products when the host or audio engine can generate I2S-compatible BCKIN, LRCIN, and DIN signals. The 24-bit, 96 kHz-capable converter provides a conventional stereo output without requiring a high-channel-count codec. Independent digital attenuation supports channel-level control in the digital domain. Designers must still address asynchronous-clock support, audio-format translation, ground partitioning, and output filtering because these implementation requirements are not fully specified in the supplied excerpts.

Professional Audio Monitor Controller
PCM1716E can support a stereo monitor-control path where 24-bit source resolution and independent left and right attenuation are useful. The digital audio processor feeds the converter, and the analog outputs are directed into the monitor’s line or headphone amplification circuitry. The part’s 28-SSOP format supports dense board layouts, while the common data formats simplify integration with existing transports. Critical evaluation should include the unavailable dynamic-range, distortion, and output-voltage specifications, which must be confirmed before setting gain or designing the output stage.
Được đề xuất
Digital-Audio Interface and Capture Card
PCM1716E is relevant to a playback-oriented digital-audio interface because it accepts several serial formats and separates left and right channels using the LRCIN signal. The BCKIN and LRCIN timing must match the source, while DIN carries the sample data. The converter supports up to 96 kHz sampling, making it appropriate for high-resolution playback paths. This usage is primarily playback because the supplied data identifies a DAC rather than an ADC; any simultaneous capture function requires a separate converter and independently verified timing architecture.

Hướng dẫn chọn lựa
Do not substitute WM8740 solely from the community claim that it is pin-by-pin compatible. Treat it as a candidate requiring manufacturer-level package, pin, electrical, and lifecycle verification. PCM1798DBR is also unsuitable as a direct replacement unless its datasheet proves compatibility with the 28-SSOP target footprint. For new designs where performance, supply voltage, or a different package is decisive, compare those parameters first and retain PCM1716E when its confirmed format support, channel attenuation, and de-emphasis meet the system requirements.

Ghi chú thiết kế
Use the manufacturer datasheet land pattern and pin table as the controlling layout references because the supplied records do not provide the complete numbered pin assignments. Place bypass capacitors close to the applicable supply pins, use a low-impedance ground reference, and route BCKIN, LRCIN, and DIN away from the analog output nets. The 28-SSOP footprint is compact, so analog and digital return paths can accidentally couple unless the reference layout is followed.
Clock and data timing must satisfy the PCM1716E interface requirements for the selected sampling rate and digital format. BCKIN, LRCIN, and DIN should be driven from the same source domain where possible, with short traces and controlled return paths. Do not assume that an asynchronous USB or network clock is accepted; verify clock generation in the source design and confirm the datasheet’s timing and de-emphasis requirements before enabling the converter.
Do not treat a community forum statement that WM8740 is pin-by-pin compatible as a released substitution. Confirm the actual package, every pin assignment, supply voltage, sampling rate, digital format, analog output level, and lifecycle status using manufacturer documentation. Similarly, PCM1798DBR should not be placed on a PCM1716E footprint merely because both are stereo DACs; the supplied comparison evidence indicates different package identifiers.
Thông tin tuân thủ
The supplied verified records identify PCM1716E as a green product and mention no Sb/Br in one feature excerpt, but they do not provide a complete RoHS, REACH, lead-free, halogen-free, or conflict-minerals declaration. Compliance fields are therefore left unknown rather than inferred.
