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.

PCM1742KE - 24-Bit 200kHz Stereo Audio DAC | Texas Instruments

The Texas Instruments PCM1742KE is a 24-bit, 200 kHz stereo audio digital-to-analog converter with an I2S digital interface, monolithic CMOS construction, and a 16-pin SSOP package. It combines two converter channels with support circuitry in one compact device for digital-to-analog signal conversion. The converter uses enhanced multilevel delta-sigma architecture with fourth-order noise shaping and 8-level amplitude quantization to support high-resolution audio playback. An audio DAC is a mixed-signal interface that converts digital audio samples into left and right analog voltage signals. Within the broader signal-chain hierarchy, it sits after a digital audio source, decoder, mixer, or host processor and before an analog output amplifier and loudspeaker or line-level destination. The PCM1742KE is therefore a precision audio DAC rather than a digital input device, codec, or power-management component. Its stereo architecture allows both channels to be processed in one integrated circuit. Key features include 24-bit resolution, operation up to 200 kHz, an I2S-compatible digital interface, and a dual-channel converter arrangement. The enhanced multilevel delta-sigma design applies fourth-order noise shaping and 8-level amplitude quantization, combining noise suppression with a relatively compact CMOS implementation. These characteristics suit digital audio equipment that requires separate left and right analog outputs while accepting digital sample data from a digital audio processor. The PCM1742KE uses separate analog and digital supply domains, an important implementation detail for mixed-signal audio systems. The TI E2E discussion identifies the PCM1742 as using dual-supply operation, with 5 V analog and 3.3 V digital rails, while noting that PCM1753 differs at pin 5 and uses a 5 V single supply. Designers should therefore preserve the target device's pin-specific supply arrangement and use the pin-description table in the manufacturer datasheet when assigning PCB nets. Typical applications include CD and DVD player analog-output sections, home-theater audio equipment, active speaker electronics, multichannel audio processors, and digital mixing consoles. It is especially relevant where a 24-bit I2S source must be converted into stereo analog signals before amplification. In such designs, the DAC output should be followed by the intended analog gain stage rather than being assumed to drive a loudspeaker directly. The primary design consideration is preserving low-noise analog behavior and correct digital clocking. Route digital-interface traces away from the analog output path, use the decoupling and layout recommendations in the manufacturer datasheet, and confirm that the source clock, serial data, and word-select timing meet the PCM1742 interface requirements. Component tolerances and amplifier selection can materially affect the final audible noise floor. This page organizes the PCM1742KE product information into a focused engineering reference covering converter architecture, package constraints, application fit, pin compatibility, sourcing questions, and design considerations. It also separates confirmed drop-in substitutions from related parts that require different supply arrangements or pin definitions, helping prevent a superficially similar replacement from becoming an unreliable board-level substitution.

The PCM1744U is designed for stereo audio systems that require a digital input and analog output without using the device as a general-purpose signal generator. Its 24-bit interface preserves a large dynamic range, while the 96 kHz sampling-rate ceiling supports common high-resolution audio formats. The 97 dB SNR specification provides a concise indication of the converter's signal quality relative to quantization noise and other internal noise sources. Typical uses include consumer audio equipment, digital media systems, multichannel audio processors, powered speakers, sound cards, and embedded audio products. In these applications, the PCM1744U accepts I2S audio from a codec, DSP, or application processor and produces two analog outputs that can feed an op-amp buffer, line driver, headphone amplifier, or speaker amplifier stage. PCB design should provide a stable low-noise supply and short analog output routing. Input and output capacitors, grounding, and the analog signal path must follow the layout guidance in the manufacturer datasheet. Because the verified snippets do not provide exact capacitor values, supply-current limits, analog output swing, or pin names, those implementation details should not be inferred from generic PCM1744-family designs.

The verified product information identifies the PCM1748 family as a 24-bit audio DAC with I2S support and a 16-SSOP package. Distributor listings also identify the PCM1748E as a stereo audio DAC and describe the device as a 24-bit converter operating with digital audio input. The available snippets mention sampling-rate values that are not fully consistent across sources, including 96 kHz, 100 kHz, and 192 kHz; therefore, the exact supported sampling-rate range should be confirmed against the manufacturer datasheet before design release. Typical signal-chain use places the PCM1748E after an audio source such as a digital interface, USB audio controller, or embedded audio processor. The digital stream is converted into left and right analog outputs for headphone, line-level, mixer, or amplifier circuitry. Because the converter is designed for stereo audio, it is useful in compact playback systems where two-channel conversion, small package size, and straightforward digital control are more important than a high channel count. Designers should verify the SSOP-16 land pattern, digital interface format, system clocking, analog output implementation, and decoupling requirements against the current Texas Instruments datasheet. Layout should keep digital clock and data routing away from analog output nodes, while supply and ground connections should follow the manufacturer’s recommended application circuit. The 16-pin SSOP package also requires careful solderability and assembly planning when lead pitch and thermal exposure are significant design constraints. This page consolidates verified manufacturer and distributor information, identifies the PCM1748E’s converter and packaging characteristics, and provides application-oriented guidance for engineers evaluating it as a stereo audio DAC.

Its 3-wire serial digital interface accepts digital audio data and clock signals, while the analog outputs provide a straightforward path to downstream amplification. The converter is designed for consumer and professional audio equipment where compactness, dynamic range, and clock-jitter performance are important. The internal fourth-order noise-shaping architecture moves quantization noise away from the most audible low-frequency region, while multilevel quantization reduces demands on the digital-to-analog conversion filters. This architecture supports accurate reproduction of music and speech signals at relatively low analog output amplitude. Clock jitter tolerance is improved compared with simpler delta-sigma converters, although system-level performance still depends on clean supplies, stable clocking, correct digital timing, and properly implemented output filtering. Typical uses include powered speakers, compact USB audio interfaces, headphone amplifier boards, digital mixing consoles, multimedia equipment, and home-audio playback modules. PCM1748E/2K is particularly suitable where two analog output channels are required but a six-channel or more complex multichannel DAC would add unnecessary cost and board area. A companion codec or digital interface must supply valid PCM data, while the DAC converts that data into left and right analog outputs. For layout, place the analog output components and their return paths close to the device, maintain a quiet analog ground reference, and separate digital clock and data routing from sensitive output nodes. Use stable low-noise supply decoupling and follow the pin-description table in the manufacturer datasheet when assigning PCB tracks.

PCM1750U - Dual 18-Bit Audio ADC | Texas Instruments | SOIC-28

The Texas Instruments PCM1750U is a dual-channel, 18-bit monolithic audio analog-to-digital converter using successive-approximation conversion and a serial interface, housed in a 28-pin SOIC package. The converter is designed for applications requiring simultaneous digital capture of two audio channels while retaining an 18-bit resolution and a compact surface-mount footprint. An audio ADC is a data-converter IC that converts left- and right-channel analog audio signals into digital sample data for transmission, storage, processing, or playback. The PCM1750U belongs to the broader ADC/DAC category, with its application-specific role defined by audio signal acquisition. It is a dual CMOS device, allowing two analog audio inputs to be represented within one package rather than requiring two separate converter packages. The principal verified characteristics are 18-bit resolution, a dual-channel architecture, successive-approximation conversion, and a serial output format. These features make the PCM1750U suitable for digital audio recording, stereo capture, multimedia equipment, and other systems that require two synchronized audio conversion channels. The distributor classification identifies the device as an audio ADC in a 28-pin SOIC package. Successive-approximation conversion implements a binary-search sequence that progressively resolves the sampled input voltage. This architecture is appropriate for audio systems requiring deterministic serial data transfer and practical converter performance. Because no complete manufacturer datasheet was included in the verified dataset, the clock frequency, conversion rate, dynamic range, full-scale range, channel isolation, and analog input impedance are not independently stated here and must be confirmed in the manufacturer datasheet. Typical implementation places the PCM1750U after stereo input conditioning, with anti-alias filtering or other analog front-end stages ahead of its analog inputs. The serial interface then connects to a digital audio processor, audio codec, microcontroller, or logic device capable of receiving the converter's data, clock, and control signals. PCB layout should keep analog and digital return paths separated, minimize digital clock coupling into the analog inputs, and provide stable bypassing near the device. The principal design trade-off is that the PCM1750U integrates only the conversion function shown in the verified information; system-level audio performance also depends on the input amplifier, anti-alias filter, reference implementation, clock source, grounding, and software configuration. Before finalizing a design, verify timing, power-supply requirements, analog input range, and pin functions against the current Texas Instruments datasheet. This page consolidates verified distributor information, source traceability, replacement guidance, and engineering-focused selection notes. It also distinguishes confirmed PCM1750U characteristics from parameters that still require datasheet verification, providing a practical basis for sourcing and early design assessment without inventing unavailable electrical details.

The Texas Instruments PCM1760P is a 20-bit, dual-input sigma-delta analog-to-digital converter with a 48 kHz sampling rate, housed in a 28-pin through-hole PDIP package. It combines a multi-bit enhanced-noise-shaping modulation stage with a decimating digital-filter function for high-resolution audio digitization. The manufacturer datasheet specifies typical total harmonic distortion plus noise of -92 dB and a maximum value of -90 dB, providing a concrete dynamic-performance benchmark for audio signal-chain design. An ADC converts continuous analog voltage signals into numerical data for processing, storage, or transmission. The PCM1760P belongs to the sigma-delta ADC family, whose architecture uses continuous-time modulation and digital filtering to shape quantization noise away from the signal band. In the broader component hierarchy, it is an ADC within the ADC/DAC category, which forms part of mixed-signal and data-conversion semiconductor systems used in professional audio, communications, instrumentation, and consumer equipment. The principal device features include two analog input channels, 20-bit conversion resolution, and operation at up to 48 kHz. Its multi-bit enhanced-noise-shaping architecture is intended to improve in-band conversion performance, while the associated decimating digital-filter section supports practical audio-rate output. The dual-channel arrangement allows simultaneous or multiplexed capture of stereo audio without requiring two separate converter packages. A 28-pin PDIP package also supports conventional through-hole PCB assembly and prototype rework. PCM1760P combines a multi-bit monolithic modulator with a monolithic decimation digital filter. In operation, each analog input is sampled and converted by the modulator before the digital filter removes high-frequency quantization noise and reduces the conversion rate. This division between analog modulation and digital filtering is central to the performance of the device. The resulting 20-bit, 48 kHz conversion capability is suited to systems that require greater nominal resolution than conventional low-cost audio converters while retaining a straightforward external interface architecture. Typical uses include stereo audio capture, professional recording equipment, broadcast monitoring, consumer audio equipment, and instrumentation requiring two-channel sampling. In each case, the ADC converts the left and right analog channels into digital samples while the internal decimation process controls out-of-band noise. System designers should also consider clock quality, analog input conditioning, grounding, decoupling, and digital-interface timing because these external factors can materially affect the converter's measured performance. For PCB implementation, place bypass capacitors close to the device supply pins and route analog and digital returns carefully to minimize shared-impedance coupling. The through-hole package simplifies inspection and manual rework, but it occupies considerably more board area than most surface-mount audio converters. Confirm clock requirements and interface signal levels against the manufacturer pin description and application guidance before finalizing the schematic. This product page combines the manufacturer-level architecture information, exact package and conversion specifications, application guidance, and drop-in-replacement evaluation for PCM1760P sourcing and engineering review. It is intended to help buyers identify the correct 28-pin audio ADC while providing practical context for signal-chain design and board implementation.

PCM1796DBR - 24-Bit 192kHz Stereo Audio DAC | Texas Instruments

The Texas Instruments PCM1796DBR is a 24-bit, 192 kHz sampling stereo audio digital-to-analog converter built on TI's advanced segment DAC architecture, housed in a 28-lead SSOP (DBR) package. It delivers balanced current outputs, digital filtering, programmable gain and DSD-compatible operation for high-fidelity audio equipment. A DAC (digital-to-analog converter) is an audio-class signal-chain IC that reconstructs a continuous analog voltage or current waveform from a digital bitstream. As a member of the broader digital-to-analog converter family, the PCM1796 belongs to the ADC/DAC category of data converters, which sit between digital audio transports and analog amplification stages, ultimately forming part of a power-management- and signal-integrity-managed audio system. Its balanced current-output topology is the classical high-end audio architecture because current-output DACs are far less sensitive to voltage-reference drift and to clock jitter than voltage-output devices. Key features include 24-bit resolution at up to 192 kHz sampling, an advanced segment DAC core for low distortion, a jitter-tolerant three-wire serial interface for left/right clock, bit clock and data, programmable output gain, selectable digital filters and support for Direct Stream Digital streams up to 200 kHz DSD. Dynamic performance is characterized by very low total harmonic distortion plus noise and high signal-to-noise ratio, with the datasheet measurement conditions defined by a 20 Hz high-pass filter and a 20 kHz AES17 low-pass filter. Internally, the data converters use TI's advanced segment DAC architecture, which divides the conversion into multiple current-steering segments to reduce the glitch energy generated at each code transition. That segmentation, combined with the jitter-insensitive data latch, is why the PCM1796 is commonly selected for CD, DVD, SACD, network and USB audio products where inter-channel and inter-sample errors are audible. Analog outputs are provided as differential current pairs so designers can balance each channel in the analog domain or drive a single-ended stage. Typical applications include CD and DVD player digital output stages, SACD and optical-disc player DAC sections, network audio streamers, USB and computer audio interfaces, digital mixing consoles, headphone amplifier front ends and multi-channel home cinema audio processors. The balanced outputs pair naturally with the analog stages found in these systems. When designing around the PCM1796DBR, treat the analog output as a current source: the output must be terminated by an I-to-V conversion stage, usually a resistor load plus an operational amplifier, and the load impedance directly shapes the achievable output voltage and distortion. Keep the digital interface short, provide a clean low-noise supply, and observe the recommended decoupling so clock jitter and supply ripple do not dominate the converter's own noise floor. This page consolidates the manufacturer specifications, a structured drop-in replacement set drawn from the same TI stereo-DAC family, and practical analog and layout guidance that a datasheet alone does not present in engineering-decision form.
