ADS802E Descripción general
An ADC is an analog-to-digital converter, a data-acquisition IC that samples a continuous voltage and maps each sample to a numeric code for processing by a microcontroller, DSP, FPGA, or digital system. The ADS802E belongs to the sampling ADC family and includes the analog input, sample-and-hold circuit, quantization function, reference, and digital interface in one device. This integration reduces external circuitry compared with discrete signal chains, while the single +5 V supply simplifies system power architecture.
Key verified characteristics include 12-bit resolution, a 10-MSPS sampling rate, single-ended and differential input capability, internal references, and pin compatibility with ADS800/ADS801. The wideband track-and-hold stage is listed at 65 MHz, helping preserve input bandwidth for high-frequency sampling applications. The device is supplied in a 28-SSOP package, and the verified distributor listing describes its industrial temperature grade and gull-wing terminal form.
The converter's architecture is intended for instrumentation, communications, industrial control, and embedded measurement systems where a compact, high-speed ADC is useful. Differential operation can help reject common-mode noise when the analog source and receiver share environmental interference. Single-ended operation is useful when the signal source is referenced to the same ground system as the converter. Engineers must still account for analog input range, reference accuracy, source impedance, sampling timing, clock jitter, and digital-interface levels in the complete design.
Typical applications include waveform capture, sensor signal conditioning, communications receivers, industrial process monitoring, and embedded data acquisition. Because the input stage is bandwidth-limited by the track-and-hold network, the input signal and amplifier must deliver adequate bandwidth and settling behavior at the selected sampling rate. The ADS802E is not a drop-in substitute for every ADC in the market; the verified pin-compatible ADS800/ADS801 family is the appropriate starting point when package and interface details match.
For layout, place input, reference, and ground connections according to the manufacturer datasheet and keep high-speed digital traces away from sensitive analog nodes. Confirm the selected package footprint and pin assignments before PCB release. The verified data does not provide complete pricing, lifecycle, compliance, or all electrical timing details, so those values must be confirmed with the manufacturer or an authorized distributor.
This page combines verified manufacturer and distributor product information with package, sourcing, application, and design guidance intended to reduce component-selection risk. It is intended as an engineering reference, not as a substitute for the complete ADS802 datasheet, application notes, or final qualification records.

Aplicaciones típicas
ADS802E es adecuado para 6 aplicacións: Industrial Process Monitoring, Communications Receiver, Waveform Capture, Sensor Signal Conditioning, Embedded Data Acquisition, Instrumentation and Test Equipment.
Industrial Process Monitoring
The ADS802E is a 12-bit, 10-MSPS ADC that can digitize sensor-derived process signals when the design requires more temporal detail than a slow control ADC. Its single-ended or differential input capability permits selection according to the transducer and receiver architecture, while differential operation can reduce common-mode disturbance in industrial wiring. The 65 MHz track-and-hold bandwidth supports fast acquisition, but the front-end amplifier must settle within the sampling interval. The verified industrial temperature grade of -40 C to +85 C is relevant to equipment operating across typical industrial environments. Use the manufacturer’s reference and layout guidance to establish input range, source impedance, decoupling, grounding, and calibration before deploying the converter in a field instrument.
Recomendado
Communications Receiver
The ADS802E can serve as the sampling element in a communications receiver when the required conversion rate and resolution are appropriate for IF, baseband, or envelope-related signal chains. Its 10-MSPS conversion rate provides a fixed sample cadence, while differential input can help reject common-mode noise introduced by cables, mixers, or adjacent digital circuitry. The 65 MHz track-and-hold bandwidth gives the input stage more bandwidth than the sampling frequency alone. Clock jitter, input settling, analog gain, and digital word interpretation remain critical for communication quality. The supplied data does not specify a particular communications standard or guaranteed spurious-free range, so engineers must validate the complete signal chain against the target modulation and frequency plan.
Recomendado
Waveform Capture
For waveform capture, the ADS802E’s 12-bit, 10-MSPS sampling architecture is useful when the waveform can be observed or processed at a rate compatible with the converter’s bandwidth and timing. Differential input is valuable when the source is balanced or when the capture system benefits from common-mode rejection. The wideband track-and-hold stage allows the input to follow rapidly changing signals, but the acquisition path still needs adequate gain, low distortion, controlled impedance, and clock distribution. The ADC output should be paired with an FPGA or DSP capable of capturing and processing the selected digital interface. Exact latency, output coding, and timing parameters must be taken from the complete manufacturer datasheet before defining a sample-accurate trigger or timebase.
Recomendado
Sensor Signal Conditioning
The ADS802E can be placed after an analog front end that converts a sensor output into a voltage suitable for the ADC input range. A 12-bit converter provides a useful balance between resolution and speed for many measurement systems, while differential input may simplify rejection of offsets and common-mode noise when the sensor interface is balanced. The sensor amplifier must settle quickly at 10 million samples per second, and the selected analog bandwidth must preserve the signal’s rise time and amplitude. ADC input capacitance, source impedance, sampling kickback, and reference behavior should be checked in the manufacturer datasheet. Calibration should account for offset, gain, and drift; the supplied verified data does not specify a universal sensor interface or calibration coefficient.
Recomendado
Embedded Data Acquisition
The ADS802E is suitable for an embedded acquisition chain that needs 12-bit samples at up to 10 MSPS and can provide a compatible digital interface to a microcontroller, DSP, or FPGA. The single +5 V supply arrangement simplifies power planning when the surrounding system already uses that rail, while the internal reference reduces the number of external precision components. The embedded controller must correctly interpret the converter’s output coding and timing, which are not fully specified in the supplied data. Firmware and FPGA logic should also account for acquisition latency, clock qualification, and buffer management. For low-power portable systems, verify total current and thermal dissipation because the verified 250-mW figure specifically describes internal-reference power and may not represent every operating mode.
Recomendado
Instrumentation and Test Equipment
Instrumentation and test equipment can use the ADS802E to acquire analog signals when a compact 12-bit converter with a 10-MSPS rate is sufficient. The device’s internal reference and single supply reduce support-component count, while the industrial temperature grade supports equipment environments identified in the verified distributor data. The acquisition front end must still provide suitable attenuation or amplification, input protection, stable reference filtering, and layout separation between analog and digital signals. Test accuracy depends on calibration, noise, gain error, INL, DNL, and the bandwidth of the complete path; these detailed specifications are not included in the supplied verified excerpts. Confirm them in the current manufacturer datasheet before setting instrument accuracy limits or writing production-test procedures.

- Broad track-and-hold bandwidth (frente a ADS801U)
Notas de diseño
Treat the analog input path as a high-bandwidth sampling system rather than a low-frequency sensor input. Estimated: at 10 MSPS, the sample interval is 100 ns, so the source impedance, amplifier settling, and ADC input capacitance must produce valid conversion results within that interval. Keep the input trace short, use a controlled return path, and verify the complete front-end bandwidth before relying on the ADS802E's verified 65 MHz track-and-hold bandwidth.
Separate sensitive analog nodes from digital output and clock routing, and provide a deliberate ground strategy around the converter. The supplied data confirms a 28-SSOP package but does not provide a manufacturer-specific stack-up or reference PCB layout. Before fabrication, obtain the current ADS802 datasheet and follow its pin, decoupling, and grounding recommendations; do not infer SSOP land patterns from a generic SSOP drawing.
Estimated: the verified internal-reference power is approximately 250 mW. If that figure applies at a 5 V operating condition, the associated reference current is approximately 50 mA by arithmetic, although total device current may differ depending on conversion activity and operating mode. Verify supply-current limits, regulator headroom, and thermal rise using the manufacturer datasheet rather than treating this derived reference current as a complete power budget.
