ADS826E - 10-Bit, 60-MSPS Pipelined ADC | Texas Instruments
MPN： ADS826E ✗ 停產ADS826E 概覽
An ADC converts an analog voltage into a digital code so that a processor, FPGA, DSP, or control system can process physical signals. The ADS826E belongs to the pipelined ADC class, a high-speed architecture commonly used in communications, instrumentation, industrial control, radar, and test equipment. Its 10-bit resolution represents 1,024 digital levels, making it suitable for applications where sample speed is more important than very fine amplitude resolution.
Key features include low differential nonlinearity of 0.25 LSB, a programmable analog input range, a power-down function, and single +5 V analog operation. The supported single-ended and differential input modes provide flexibility for source arrangements and signal conditioning. Internal or external reference selection allows the converter to fit designs with different accuracy and scaling requirements. The 28-SSOP package supports conventional PCB assembly but occupies more board area than a small QFN package.
The ADS826E uses a proprietary pipelined conversion method, as identified by the verified distributor and datasheet listings. The architecture supports continuous high-rate sampling while retaining a compact 28-pin SSOP package. Its +3 V/+5 V logic compatibility helps simplify interfacing with digital controllers, although the digital input thresholds, timing, and supply sequencing must still be checked against the manufacturer datasheet before layout release.
Typical applications include communications receivers, data acquisition front ends, industrial measurement systems, oscilloscope and instrumentation channels, digital feedback and control loops, and embedded signal processing. For a new design, verify the required input range, reference source, digital interface timing, power sequencing, and thermal performance in the official ADS826E datasheet. Pricing and availability should also be checked with authorized distributors because the verified search data does not provide a current numeric price or lead time.
A key design consideration is the analog input network. Input impedance, source capacitance, full-scale range, and the selected differential or single-ended topology must be evaluated together. Keep routing compact, provide the required bypass capacitors, and control clock and digital-output crosstalk. Because the verified data identifies the converter as a 60-MSPS, 10-bit pipelined ADC, PCB signal-integrity and clock routing decisions can materially affect sampling accuracy.

典型應用
ADS826E 適用於 6 應用s: Communications Receiver Front End, Industrial Data Acquisition, Test and Measurement Instrumentation, Digital Control and Feedback Systems, RF and Wireless Signal Conditioning, Embedded Signal Processing.
Communications Receiver Front End
The ADS826E fits communications receiver front ends where rapid conversion and compact sampling resolution are more important than ultra-high resolution. Its verified 60 MSPS throughput supports high-rate signal capture, while 60 dB SNR and 74 dBFS SFDR provide useful dynamic performance for receiver signal chains. Use it behind a band-limiting or gain-control stage when the source is not already constrained to the ADC input range. The single-ended or differential input option allows the analog interface to match the receiver architecture. Clock routing, reference stability, and digital-output timing require careful layout, especially when the converter feeds an FPGA or DSP. The supplied data does not state the exact full-scale input range or digital-interface protocol, so those details must be verified from the official datasheet before finalizing the receiver design.
推薦
Industrial Data Acquisition
The ADS826E is appropriate for industrial data-acquisition systems that need to sample changing analog quantities at a relatively high rate. The 10-bit resolution gives 1,024 representable code levels, while 60 MSPS allows the converter to capture transient behavior rather than only slow process variables. A programmable input range and single-ended or differential input can simplify adaptation to sensor amplifiers, transducer bridges, or industrial signal-conditioning boards. Designers should place the converter close to the front end, protect the analog path from digital switching noise, and verify reference accuracy against the required measurement resolution. The verified data does not provide input impedance, common-mode limits, or exact timing values, so the analog interface must be completed with manufacturer documentation rather than assumptions.
推薦
Test and Measurement Instrumentation
The ADS826E can serve as the sampling element in oscilloscope-like, waveform, or automated test equipment when the instrument needs a fast 10-bit conversion path. Its 60 MSPS rate provides temporal resolution for repetitive or changing waveforms, while the 74 dBFS SFDR figure is relevant when minimizing distortion and spurs matters. A suitable front end should provide attenuation, gain, input protection, and anti-alias filtering before the ADC. Differential input can reduce sensitivity to common-mode noise when the circuit and source permit it, but the exact input range and source requirements are not included in the verified data. Confirm calibration flow, reference strategy, clock jitter tolerance, and data-capture interface from the manufacturer datasheet before treating the converter as a measurement-grade instrument.
推薦
Digital Control and Feedback Systems
The ADS826E can be used in feedback and control applications where a controller must observe a rapidly varying analog condition. The 60-MSPS conversion capability provides frequent samples, while the 10-bit code width can represent approximately 1,024 quantization levels for a selected input range. In a practical loop, the ADC should follow a defined anti-alias filter and be paired with a stable reference so that changes in the digital result correspond predictably to changes in the sensed variable. The converter’s supported internal or external reference options allow the design team to align the measurement path with system calibration requirements. Since the supplied sources do not provide latency, input impedance, or timing specifications, control-loop bandwidth and stability must be verified using the official datasheet and measured hardware behavior.
推薦
RF and Wireless Signal Conditioning
The ADS826E may be used in RF or wireless signal-conditioning systems after suitable frequency conversion, attenuation, and filtering. Its 60 MSPS sampling rate can capture intermediate-frequency or other bounded-band signals when the analog front end establishes the required bandwidth and gain. The 60 dB SNR and 74 dBFS SFDR are useful starting points for evaluating receiver-chain performance, although RF converters also require careful consideration of clock jitter, aliasing, reference noise, and gain distribution. The verified data does not specify integrated frequency response, input impedance, or jitter tolerance, so it does not support a complete RF suitability claim. Use the device as a candidate only after comparing its datasheet limits with the full receiver specification and validating the analog and digital layout.
推薦
Embedded Signal Processing
The ADS826E can feed an embedded processor, FPGA, or DSP when a compact high-speed ADC is needed for local signal processing. The 60-MSPS conversion rate can support algorithms that require dense time-domain observations, such as waveform classification, vibration monitoring, or fast feedback sampling. The 10-bit resolution is adequate for many decision and control tasks, but system performance depends on analog gain, reference accuracy, anti-alias filtering, and the processor’s ability to consume the converter’s digital output. The verified data does not identify the digital interface format or timing, so the system architect must confirm compatibility before selecting the part. Mechanical vibration and thermal design should also be evaluated because sensor noise and power-supply variation can dominate a nominally 10-bit measurement.

設計說明
Treat the ADS826E analog path as a high-speed signal path. Place the converter close to the input driver, reference source, and bypass network; keep analog and digital returns separated where the datasheet layout guidance permits. Route the sampling clock with short, controlled-impedance traces and avoid routing it beneath sensitive analog nodes. Confirm the exact SSOP land pattern and recommended decoupling values in the manufacturer datasheet before PCB release.
The verified data specifies single +5 V analog operation and +3 V/+5 V logic compatibility. Provide local bypass capacitance at the supply pins and verify sequencing between analog, digital, and reference rails. The verified snippets identify a 265 mW converter power figure, but they do not provide complete supply-current limits or transient specifications; use the official datasheet to size regulators and ensure startup does not violate input-voltage limits.
Because ADS826E is a 60-MSPS pipelined ADC, clock jitter, clock-to-data timing, and data-output routing can affect system performance even when the analog input is well conditioned. Use a low-noise clock source, maintain short digital traces, and provide a clean return path for high-speed signals. Validate timing with the actual controller, FPGA, or DSP rather than relying only on nominal converter specifications.
Do not infer pin functions, full-scale input limits, reference accuracy, or interface timing from distributor snippets alone. The verified data confirms the 28-SSOP package, 10-bit resolution, 60-MSPS rate, input modes, reference options, and power figure, but it does not provide the complete pinout or electrical limits. Check the official ADS826E datasheet for absolute maximum ratings, recommended operating conditions, pin descriptions, timing, and application-circuit values.
