AD677JD - 16-Bit 100 kSPS Serial ADC | Analog Devices
MPN: AD677JD ⚠ Lần mua cuốiAD677JD Tóm tắt
A sampling ADC converts an analog input into a digital code at a specified sample rate. The AD677JD belongs to the ADC and data-converter hierarchy, where its 16-bit resolution supports detailed measurement while its 100 kSPS rate handles rapidly changing analog signals. The serial output reduces pin count and supports compact instrument and industrial-control designs.
Key verified features include 16-bit resolution, 100 kSPS throughput, no missing codes, on-chip autocalibration, −99 dB THD, 92 dB S/(N+D), and 1 MHz full-power bandwidth. The manufacturer describes the conversion process as switched-capacitor/charge redistribution with digitally corrected internal nonlinearities through on-chip autocalibration.
The AD677 family is available in 16-pin narrow plastic DIP, 16-pin narrow side-brazed ceramic, and 28-lead SOIC packages. AD677JD is the 16-pin CDIP ordering variant identified in distributor data. Its operating range is 0°C to 70°C, making it appropriate for commercial-temperature instrumentation where that range is acceptable.
Typical uses include industrial process measurement, laboratory data acquisition, sensor interfaces, waveform capture, and embedded measurement systems. Designers should verify supply tolerances, reference requirements, digital-interface timing, acquisition timing, and calibration behavior against the manufacturer datasheet before layout or firmware implementation.
For AD677JD sourcing, compare distributor inventory, lifecycle status, and price as of 2026-10-22. The 16-pin DIP footprint is mechanically straightforward, but digital timing, analog input conditioning, and power-supply noise still determine practical performance.

Ứng dụng tiêu biểu
AD677JD phù hợp cho 6 Áp dụngs: Industrial Process Measurement, Laboratory Data Acquisition, Sensor Signal Conditioning, Waveform and Transient Capture, Embedded Measurement Systems, Environmental Monitoring.
Industrial Process Measurement
The AD677JD is suitable for industrial process-measurement systems that digitize pressure, temperature, flow, or level signals at up to 100 kSPS. Its 16-bit resolution provides a detailed numerical representation for control and monitoring, while the on-chip sample-and-hold function helps isolate the input during conversion. Use a protected analog front end, stable reference, and properly decoupled supply. The 0°C-to-70°C range is appropriate only where the enclosure and signal chain remain within that commercial-temperature envelope. Because the part is Last Time Buy, production designs should include supply-risk review and alternate-part qualification.

Laboratory Data Acquisition
AD677JD can serve as the conversion element in a laboratory data-acquisition front end when the experiment requires 16-bit numerical resolution and a maximum rate of 100 kSPS. The serial output reduces the number of parallel data lines, allowing the board to route control and conversion data efficiently. Designers should account for the 10 us total conversion time, acquisition settling, digital clocking, and the analog input bandwidth limit of 1 MHz. Add input protection and anti-alias filtering appropriate to the measured signal. The commercial 0°C-to-70°C range is suitable for typical indoor instrumentation.
Được đề xuất
Sensor Signal Conditioning
The AD677JD is useful for digitizing sensor outputs that require more resolution than a lower-bit control ADC while still supporting a moderate sampling rate. A sensor amplifier can drive the analog input, followed by filtering and the converter's on-chip sample-and-hold function. The 16-bit code width helps preserve small signal variations, but system accuracy still depends on reference stability, amplifier noise, grounding, and calibration. The AD677JD's serial interface helps reduce PCB signal count in a multi-channel acquisition card. Validate input range and settling behavior in the complete signal chain rather than relying on nominal converter resolution alone.

Waveform and Transient Capture
For selected waveform and transient-capture tasks, AD677JD can acquire up to 100 kSPS with 16-bit resolution. The 1 MHz full-power bandwidth provides useful margin for signals within the converter's stated bandwidth, while the 10 us conversion time defines the timing budget. Applications must still perform their own sampling, buffering, triggering, and signal reconstruction. A front-end filter should reject out-of-band energy before the ADC, and the digital interface must meet serial timing requirements. The device is most appropriate when 100 kSPS is sufficient and low-noise, deterministic conversion is more important than very high throughput.

Embedded Measurement Systems
AD677JD can be integrated into embedded measurement equipment where an analog input must be converted and serialized to a controller, FPGA, or data logger. Its 16-bit output provides a useful format for calibrated measurement systems, and the serial interface simplifies connections compared with a wide parallel bus. The system designer must define clocking, chip-select or frame timing, data capture, and calibration sequencing around the converter's 10 us conversion time. A stable reference and careful layout are especially important because converter performance is measured under defined analog conditions. The DIP package favors through-hole prototyping and repairable industrial equipment.
Được đề xuất
Environmental Monitoring
The AD677JD can be used in environmental monitoring equipment for sampled temperature, humidity, gas, or vibration-derived signals when the required bandwidth is below 100 kSPS. Its 16-bit resolution can capture small changes in conditioned sensor outputs, while the on-chip sample-and-hold supports sequential acquisition. The converter should be paired with sensor protection, filtering, calibration storage, and a stable reference. The commercial temperature range requires enclosure thermal design or a different qualified AD677 suffix when field temperatures exceed 70°C. Because lifecycle status is Last Time Buy, long-life monitoring products should plan a controlled replacement strategy.

Ghi chú thiết kế
Use a clean, well-decoupled supply for the nominal 12 V analog power requirement and follow the manufacturer’s recommended bypass and reference connections. Keep high-current digital return paths away from the analog input and reference network. Because the supplied data does not state allowable supply tolerance, current consumption, or decoupling values, use the official AD677 datasheet for those values rather than estimating them.
Route the analog input with short traces, minimize loop area, and place input filtering close to the converter. Provide a stable reference path and keep serial clock and data traces away from sensitive input and reference nodes. The AD677JD uses a 16-pin CDIP package, so provide adequate through-hole spacing and mechanical clearance around the device; exact pin functions and numbering must be taken from the manufacturer datasheet.
Do not assume that AD677JD, AD677JNZ, and AD677AD are interchangeable: suffix-specific package, temperature, timing, and supply details may differ. Also do not interpret 16-bit nominal resolution as guaranteed end-to-end measurement accuracy without checking reference stability, analog front-end noise, and calibration. Since the AD677 family is marked Last Time Buy, verify lifecycle status and obtain a supplier allocation before committing to production.
Thông tin tuân thủ
The supplied verified data identifies the manufacturer, product family, package, operating range, lifecycle status, and ADC specifications, but does not provide compliance declarations. Compliance fields therefore remain unknown.
