ADS825E - 10-Bit 40-MSPS Pipeline ADC | Texas Instruments
MPN: ADS825E ✓ AktifADS825E Genel Bakış
A sampling ADC converts an analog waveform into a sequence of digital codes at a controlled sampling rate. The ADS825E belongs to the ADC, data-converter IC, and semiconductor hierarchies and is intended for systems that require modest resolution but relatively high conversion throughput. Its 10-bit quantizer provides 1,024 code levels, while the 40-MSPS sampling rate supports high-speed measurement, communications, industrial control, and instrumentation signal chains.
Key features include 40-MSPS operation, 10-bit resolution, single-ended or fully differential input capability, and internal/external reference options. The verified feature summary reports 60 dB signal-to-noise ratio, 72 dBFS spurious-free dynamic range, and 190 mW power. ADS825E accepts a +3 V clock input according to the TI ADS825 product data, while the package is identified as SSOP-28. These attributes make the converter suitable when compact size and conversion speed matter more than 12-bit or higher numerical resolution.
The TI ADS825 family is described as pin-for-pin compatible with the 10-bit ADS823, ADS826, and ADS828 families in SSOP-28. This compatibility supports upgrade paths to higher sampling frequencies, although the replacement must be checked for the exact electrical requirements of the target system. The ADS825E also supports power-down operation and programmable input attenuation according to the family-level description, helping designers manage power and signal conditioning requirements.
Typical applications include industrial process measurement, communications infrastructure, test equipment, motor-control feedback, and embedded signal acquisition. In a motor-control system, the ADC can sample current or position feedback, while in communications equipment it can digitize intermediate-frequency or baseband signals. Differential operation can improve common-mode rejection in balanced analog front ends, while single-ended operation simplifies lower-cost sensor interfaces. The verified distributor listing describes the ADS825E as a 10-bit ADC with one input, pipelined architecture, and internal/external reference capability.
A key design consideration is analog-input conditioning. The input range, reference choice, clock amplitude, source impedance, and sampling network must be verified against the manufacturer datasheet before layout is finalized. This page consolidates verified distributor information, family compatibility data, pin-compatible alternatives, and application guidance that is not typically available from a basic distributor search result.

Tipik Uygulamalar
ADS825E için uygundur 6 uygulamas: Industrial Sensor Signal Acquisition, Communications IF Digitization, Motor Control Feedback, Test and Measurement Equipment, Data Acquisition and Control, Power and Process Monitoring.
Industrial Sensor Signal Acquisition
The ADS825E fits industrial sensor acquisition when the measured signal can be conditioned into a suitable single-ended or differential analog range. Its 40-MSPS sampling rate gives substantial timing margin relative to many slow sensor signals, while 10-bit resolution supports compact measurement systems. Use programmable attenuation and the internal or external reference option to match transducer output, then protect the analog path against overvoltage and common-mode excursions.
Önerilen
Communications IF Digitization
ADS825E can digitize intermediate-frequency or other communications signals when 10-bit dynamic range is adequate. The verified 40-MSPS rate supports high-speed sampling, while the 60 dB SNR and 72 dBFS SFDR figures provide documented baseline performance for signal-chain evaluation. Differential operation is attractive when the analog front end presents balanced nodes, although clock jitter and input filtering must be analyzed against the desired carrier frequency.
Önerilen
Motor Control Feedback
The ADS825E is suitable for motor-control feedback paths that require sampling current, position, or other analog control variables. A 40-MSPS converter provides fast timing for control-loop observation, and differential input can improve behavior in systems with balanced current-sense or position-sensor signals. The design should verify that the sensor bandwidth, anti-alias filter, ADC input range, and digital output timing satisfy the controller requirements.
Önerilen
Test and Measurement Equipment
ADS825E can serve as the conversion element in oscilloscope-like, waveform, or automated test equipment when 10-bit resolution is acceptable. Its pipelined architecture and 40-MSPS sampling rate support high-speed capture, while internal or external reference flexibility helps establish a repeatable measurement chain. Designers should account for the reference accuracy, input full-scale range, settling behavior, and data-capture interface in the surrounding instrumentation.
Önerilen
Data Acquisition and Control
The converter is appropriate for embedded data-acquisition systems that sample analog measurements at moderate-to-high rates and transmit digital results to a controller. ADS825E’s 10-bit quantization, 40-MSPS sampling, and single-ended or differential input modes make it useful for compact industrial or instrumentation platforms. Validate the digital interface timing and ensure the selected microcontroller or FPGA can receive the converter output without adding timing violations.
Önerilen
Power and Process Monitoring
ADS825E can be used in process-monitoring systems where multiple sensor conditions must be converted quickly and with consistent reference behavior. Single-ended inputs simplify grounded sensor channels, while differential inputs can support isolated or bridge-based sensing stages. The programmable attenuation function helps bring different signal ranges into the ADC range, but calibration and anti-aliasing remain necessary for accurate process measurements.

Tasarım Notları
Keep the analog input path short and place the first anti-aliasing or sampling components close to the ADS825E. The 40-MSPS sampling rate requires attention to trace impedance, return paths, reference decoupling, and clock distribution. Use a controlled clock source and verify timing and jitter against the TI datasheet before finalizing the layout.
Decouple the ADS825E supply close to the device with the manufacturer-recommended capacitance and route ground returns without long shared paths. The verified feature summary lists 190 mW power, but actual dissipation depends on operating mode and clock activity. Confirm reference startup, supply sequencing, and power-down behavior against the official datasheet.
Treat the analog input, reference, clock, and digital output sections as separate layout regions. Avoid routing fast digital signals beneath sensitive analog nodes, and provide a continuous ground reference where possible. Because the package is SSOP-28, inspect solder-joint accessibility and thermal behavior during assembly and rework planning.
