ADS828E Visão geral
An ADC is an analog-to-digital converter, a semiconductor that samples an analog voltage and converts it into a digital code for processing, storage, measurement, or transmission. The ADS828 belongs to the pipeline ADC and data-converter hierarchy, where internal stages operate in sequence to balance conversion speed with circuit complexity. The ADS828E is therefore positioned between general-purpose low-speed ADCs and more complex high-resolution high-speed converters.
Key verified features include a resolution of 10 bits, a maximum sampling rate of 75 MSPS, one input, a pipelined architecture, and a 28-pin SSOP package. TI states that the ADS828 is pin compatible with the 10-bit, 40 MSPS ADS822 and ADS825, and with the 10-bit, 60 MSPS ADS823 and ADS826. That compatibility makes the ADS828E a potential board-level upgrade path when a design needs more sampling speed without changing its ADC footprint.
The ADS828E is a pipeline CMOS ADC designed around single-ended input operation and differential operation for added spurious performance. Differential operation can help reduce common-mode sensitivity and may improve signal integrity when the analog front end and routing are designed appropriately. The exact input range, reference requirements, output timing, power consumption, and electrical limits were not supplied in the verified search excerpts, so those values must be confirmed in the manufacturer datasheet before design release.
Typical uses include industrial control and data acquisition, communications infrastructure, instrumentation, signal monitoring, and embedded measurement systems. A 75-MSPS conversion rate is useful when the system must sample waveforms or rapidly changing analog signals, while 10-bit resolution suits control loops, diagnostics, and digital signal processing stages that do not require very high spectral resolution. The single +5 V supply also simplifies system power architecture compared with converters requiring multiple rails.
The primary design consideration is to preserve analog signal integrity from the sensor or amplifier through the ADC input. Use short, controlled-impedance routing, a stable reference arrangement, and decoupling appropriate to the manufacturer recommendations. Confirm acquisition timing, output interface, input range, and clock polarity against the ADS828 datasheet. The page also identifies compatible ADS822E, ADS825E, ADS823E, and ADS826E family options, but their differing sampling rates should be treated as functional trade-offs rather than identical replacements.
This product record consolidates the verified TI specifications, distributor identification, package information, and documented pin-compatible family references into an engineering-oriented selection and design reference.

Aplicações típicas
ADS828E é adequado para 6 aplicaçãos: Industrial Data Acquisition, Communications Signal Monitoring, Instrumentation and Waveform Capture, Motor and Power Control, Embedded Signal Processing, Portable Measurement Systems.
Industrial Data Acquisition
ADS828E fits industrial data-acquisition modules that need to sample rapidly changing sensor or process signals at 75 MSPS. Its 10-bit resolution provides a straightforward digital representation for control, monitoring, or downstream DSP, while the single +5 V supply reduces power-supply complexity. Use a controlled driver and reference arrangement, and verify acquisition timing, input range, and analog bandwidth in the manufacturer datasheet.
Recomendado
Communications Signal Monitoring
ADS828E can digitize intermediate-frequency or other communications-related analog waveforms where a 75-MSPS sampling rate and 10-bit resolution are sufficient. Differential operation may improve spurious performance in a properly balanced analog front end. The design must preserve clock and data timing over the required frequency range and should confirm output interface and acquisition behavior against the TI documentation.
Recomendado
Instrumentation and Waveform Capture
For instrumentation, ADS828E provides a fast sampling path for oscilloscope-like waveform capture, transient monitoring, and laboratory measurement systems. The 10-bit result is adequate for many display, trigger, and analysis functions when the analog front end limits system noise. Validate input bandwidth, settling behavior, and pipeline latency for the intended acquisition mode before choosing sampling or record length.
Recomendado
Motor and Power Control
ADS828E can support high-speed feedback and monitoring in motor-control or power-control systems where current and voltage signals must be sampled quickly. Its 75-MSPS capability provides faster observations than many low-speed control ADCs, but the selected analog amplifier must preserve signal amplitude and phase accuracy through the required control bandwidth. Grounding, isolation, and common-mode limits require application-specific review.
Recomendado
Embedded Signal Processing
ADS828E is useful when an embedded controller or FPGA needs a parallel, high-speed ADC stream for filtering, demodulation, or real-time analysis. The 10-bit output can map directly into common digital pipelines when voltage, timing, and output-format requirements are confirmed. Designers should define the clock source and capture timing early, because the conversion-rate difference between compatible ADS828 family devices can change downstream buffering requirements.
Recomendado
Portable Measurement Systems
ADS828E can serve portable instruments when low supply count and compact conversion are important, although the exact power-consumption figure is not present in the supplied data. The 75-MSPS path supports fast sensor sampling, and differential operation can help control common-mode effects in field equipment. Battery-powered designs should verify supply current, thermal behavior, and input signal range before committing to the converter.

Notas de projeto
Keep the analog input path short and place the ADC-side decoupling according to the TI recommended layout. Route the analog signal away from digital clock and data lines, use a continuous ground reference where practical, and keep the input network close to the converter. Because the verified data does not specify the input range or recommended capacitance values, do not select capacitors or termination networks without checking the manufacturer datasheet.
Treat clock quality as part of the conversion signal path. Provide a stable sampling clock with low jitter, confirm the required clock polarity and timing, and account for the difference between 75 MSPS ADS828E operation and the lower 40 MSPS or 60 MSPS compatible family members. The supplied excerpts do not include acquisition time, output timing, or allowed clock specifications, so these values must be verified before FPGA or microcontroller capture logic is finalized.
Do not assume that pin compatibility guarantees drop-in behavioral equivalence. ADS822E and ADS825E are documented at 40 MSPS, while ADS823E and ADS826E are documented at 60 MSPS, compared with 75 MSPS for ADS828E. Verify input range, reference voltage, power sequencing, output timing, conversion latency, and system calibration after any substitution. The verified excerpts do not provide those alternate-device values, so the full datasheets are required.
Informações de conformidade
The supplied excerpts identify the part as an industrial-temperature ADC but do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Compliance fields are therefore unknown rather than assumed.
