The Analog Devices AD1674AR-REEL is a complete, multipurpose 12-bit successive-approximation analog-to-digital converter (ADC) with an integrated sample-and-hold amplifier (SHA), a 10 V on-chip voltage reference, an internal clock and three-state output buffers for direct microprocessor interface, packaged in a 28-SOIC (7.50 mm body width). It delivers 100 kSPS throughput and is specified over the industrial -40C to +85C temperature range. The 28-pin SOIC (R-28) form factor uses Tape & Reel (REEL) packaging per Analog Devices ordering code. A successive-approximation ADC is a converter architecture that resolves one bit per internal clock cycle by comparing the sampled input against a precision DAC. Modern SAR ADCs integrate a sample-and-hold amplifier on the input so the user does not have to drive the converter with a continuous low-impedance signal - this widens the input bandwidth and simplifies the front-end filter design. The AD1674 fits into the converter hierarchy as: ADC -> SAR ADC -> monolithic complete ADC -> data-acquisition IC, and bridges industrial analog signal chains and 8-/16-bit microprocessor buses. Key differentiating features of the AD1674 include its complete monolithic integration (SHA + reference + clock + buffers in one die), industry-standard pinout pin-compatible with the legacy AD574A and AD674A, 10 us conversion time, three-state bus outputs with logic/control pins (CS, R/C, CE, A0, 12/8, STS) for direct 8-bit or 16-bit microprocessor hookup, and bipolar/unipolar input ranges via pin strapping. The internal buried-Zener reference trims to 10.00 V +/-0.5%, eliminating external reference components. Internally, the converter uses a precision thin-film DAC array, a high-speed comparator and a successive-approximation register clocked by an internal RC oscillator. The SHA front-end can acquire full-scale inputs in under 1 us, supporting the 100 kSPS throughput; the wideband sample-and-hold supports 12-bit accuracy across the full Nyquist bandwidth, so AC inputs up to 50 kHz can be digitized with negligible aperture distortion. Output coding is user-selectable for unipolar (0-10 V, 0-20 V) or bipolar (-5 V to +5 V, -10 V to +10 V) input ranges. Typical applications for the AD1674AR-REEL include industrial process-control data acquisition front ends, instrumentation and measurement systems, multichannel analog input boards with multiplexer scanning, scan-digitizer cards and legacy AD574A/AD674A designs that need a faster, SHA-equipped upgrade. The R-grade (industrial) temperature range and 28-SOIC footprint make it a drop-in replacement for older designs requiring faster sample rates without a layout change. When designing, note that the converter draws significant supply current - place 10 uF tantalum and 0.1 uF ceramic bypass capacitors close to the AVcc and DVcc pins and use a star-ground topology. Avoid switching the analog input while STS (status) is low; violating this timing window injects conversion errors.

Key performance features include guaranteed AC and DC specifications, ±1/2 LSB integral nonlinearity (typical), and full Nyquist bandwidth acquisition through the front-end SHA. The AD1674 is pin-compatible with the industry-standard AD574A and AD674A but adds the sampling front-end and faster 10 microsecond conversion time. Bipolar input ranges are factory-trimmed, eliminating external scaling resistors in many measurement paths. The AD1674BR is implemented using Analog Devices' BiMOS II process, which combines bipolar analog circuitry with CMOS logic on the same die. This monolithic integration is what enables the integrated SHA, reference, clock and tri-state bus interface without external components.

Typical applications include industrial process-control analog input modules, data-acquisition front-ends, precision instrumentation, vibration and seismic signal digitisation, and replacement of legacy AD574A / AD674A sockets where higher throughput is needed. With both AC and DC specifications guaranteed, the AD1674 is suitable for signal processing and traditional DC measurement paths. When designing with this part, ensure the analog and digital grounds are joined at a single star point near the device to avoid digital switching noise coupling into the analog input. Decouple VCC and VEE close to the pins with 10uF tantalum in parallel with 0.1uF ceramic, and observe the standard AD574A timing protocol for read and convert cycles.
