PCM1741E - Stereo 24-Bit Audio DAC | Texas Instruments
MPN: PCM1741E ✓ NakahandaPCM1741E Ulas
An audio DAC is a data-converter IC that converts digital audio samples into analog voltage signals suitable for headphone, line-level, or downstream power-amplifier stages. In the electronic-component hierarchy, the PCM1741E is an audio DAC, a digital-to-analog converter, a data-converter IC, and a member of the broader semiconductor and signal-processing device categories. Its stereo architecture supports two audio channels while reducing the number of separate converter packages required.
The PCM1741E uses Texas Instruments’ enhanced multilevel delta-sigma architecture. The converter architecture employs fourth-order noise shaping and 8-level amplitude quantization to provide excellent dynamic performance and improved tolerance. The verified distributor data identifies the resolution as 24 bits, the interface as I2S, the channel count as two, and the maximum sampling rate as 100 kHz. Its operating temperature range is -25°C to +85°C.
A 2.7 V to 3.6 V single-supply operating range supports low-voltage portable and embedded audio designs. The PCM1741E accepts both analog and digital supply connections, and the digital interface enables connection to an audio codec, processor, digital audio transceiver, or other source capable of supplying the required I2S data. Exact clock, output-filter, analog-output, and absolute-noise specifications not exposed by the verified search data remain marked as data needed rather than being inferred.
Typical applications include portable digital audio players, compact consumer-audio equipment, multimedia terminals, USB or network audio accessories, and other stereo playback systems operating from a 3.3 V rail. The 24-bit resolution and 100 kHz sampling capability suit digital audio paths where compactness and integrated stereo conversion are important. A suitable headroom amplifier, reconstruction filter, and output-routing network are still required where the analog output must drive a higher-power load.
The primary design consideration is analog-output implementation. The PCM1741E is a converter, not a power amplifier, so its output network must be designed around the verified interface and application requirements. Layout should separate sensitive analog routing from digital clock and data paths, use a low-noise 3.3 V supply, and follow the manufacturer datasheet for bypassing and output filtering once those circuit details are available.
This product page consolidates the verified manufacturer, distributor, pricing, package, interface, channel-count, and resolution information. It also identifies pin-compatible family alternatives, highlights missing technical fields explicitly, and provides selection and design guidance beyond the basic distributor listing.

Tipikal na mga Gamit
PCM1741E ay nararapat para sa 6 aplikasyons: Portable Digital Audio Player, USB Audio Accessory, Multimedia Terminal Audio Output, Network Audio Player, Compact Audio Interface, Consumer Audio Playback Module.
Portable Digital Audio Player
The PCM1741E fits a portable stereo playback path because it combines two 24-bit DAC channels in an SSOP-16 package and operates from a 2.7 V to 3.6 V supply. An I2S-capable audio processor can send digital samples directly to the converter, while the analog outputs feed a line-level amplifier or headphone driver. The 100 kHz maximum sampling capability supports higher-rate source material, although the final usable bandwidth still depends on the digital source, reconstruction filter, and analog stage. Using both converter channels also reduces package count compared with discrete single-channel DAC solutions.
Inirekomenda
USB Audio Accessory
PCM1741E can serve as the stereo output stage of a USB audio adapter when the upstream USB audio controller supplies compatible I2S data and clock signals. Its two-channel architecture maps naturally to left and right playback channels, while the 24-bit resolution provides a suitable digital-audio conversion format. The 2.7 V to 3.6 V operating range simplifies integration with common 3.3 V digital systems. Designers must still account for ground separation between USB data and analog output paths, provide supply bypassing, and implement the required reconstruction and output filtering.
Inirekomenda
Multimedia Terminal Audio Output
The PCM1741E is appropriate for multimedia terminals requiring compact, high-resolution stereo playback. Its two integrated DAC channels reduce board area compared with separate converter packages, and the I2S interface supports connection to digital-audio engines found in playback equipment. The converter’s 100 kHz sampling capability accommodates high-rate streams, while the 3.3 V-compatible supply range reduces power-conversion complexity. The implementation should preserve short analog traces, use a stable low-noise supply, and place filtering components where they can load the analog outputs predictably.
Inirekomenda
Network Audio Player
A network audio player can use PCM1741E to convert decoded digital audio into stereo analog signals after network reception, buffering, and decoding. The converter accepts I2S data and supports sampling rates up to 100 kHz, making it suitable for common high-resolution playback streams when the upstream processor supports the corresponding clocking mode. Its integrated two-channel architecture helps conserve board area in compact network speakers and stereo endpoints. Care should be taken to isolate switching Ethernet, Wi-Fi, and processor power sections from the analog output path.
Inirekomenda
Compact Audio Interface
PCM1741E can form the playback side of a compact two-channel audio interface because it provides two synchronized DAC outputs in a 16-pin SSOP package. The I2S interface is compatible with digital audio engines that transmit left and right channel data, while 24-bit resolution and up to 100 kHz sampling provide useful operating headroom for music capture or monitoring equipment. A practical implementation requires external analog filtering and a line or headphone amplifier because the PCM1741E is a converter rather than a power-output stage.
Inirekomenda
Consumer Audio Playback Module
The PCM1741E is suitable for modular consumer-audio playback designs that use a 3.3 V digital rail and need two analog output channels. Its monolithic stereo implementation limits the number of converter packages, and its I2S interface simplifies connection to source-controller logic. The 100 kHz sampling-rate capability supports high-rate digital streams, while the -25°C to +85°C operating range suits many indoor commercial products. Final board design should follow the manufacturer reference layout for grounding, decoupling, clock routing, and analog-output filtering.

Talaan ng Disenyo
Keep the PCM1741E analog outputs, reconstruction-filter components, and analog ground returns compact and physically separated from digital clock, data, and switching-supply nodes. The verified data confirms separate analog and digital supply connections, making careful partitioning especially important. Ground and power-return paths should follow the manufacturer reference layout once obtained, because an incorrectly arranged output ground can degrade channel performance even when the converter operates within its stated supply range.
Provide a stable 2.7 V to 3.6 V supply with local high-frequency bypassing at the converter's analog and digital supply pins. Place the bypass capacitor close to the relevant device pin and use the capacitor values and topology specified in the manufacturer datasheet. Since the verified excerpts do not disclose the required capacitor values, ESR, or startup sequence, do not infer them from generic audio-circuit examples.
Route the I2S data and clock signals as controlled-impedance digital traces, with clock routing prioritized because timing margin is generally more sensitive to loading and crosstalk than the data path. Avoid routing digital signals beneath the analog outputs or output-filter components. The verified sources identify an I2S interface and up to 100 kHz sampling, but exact setup and hold-time requirements must be obtained from the manufacturer documentation before finalizing timing constraints.
Do not assume that equal SSOP-16 package dimensions guarantee functional interchangeability. Before substituting PCM1742E, PCM1742EG4, PCM1740E, or PCM1743E, compare pin names and directions, analog and digital supply pins, master or slave clock behavior, reset requirements, sample-rate support, output circuitry, and decoupling. The supplied search excerpts establish family and package proximity but do not expose the complete pin tables.
Impormasyon ng Pagsunod sa Kautusan
The verified search excerpts do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not applicable because this is an audio converter rather than an automotive-qualified device, and no AEC-Q100 claim was provided.
