The Analog Devices AD7674ASTZ is a high-performance, low-power, 18-bit charge redistribution Successive Approximation Register (SAR) fully differential analog-to-digital converter (ADC) engineered for precision data acquisition. Running on a single 5V power supply, this integrated circuit contains a high-speed 18-bit sampling ADC, an internal conversion clock, an error correction circuit, an on-board reference buffer, and versatile parallel and serial system interface ports. Because its advanced SAR architecture features absolute zero pipeline delay, the component delivers precise performance that makes it perfect for multi-channel multiplexed designs.
The AD7674ASTZ is currently In Stock and ready for immediate shipping at Perceptive Components. As a leading independent distributor, we ensure 100% authenticity, comprehensive quality control testing, and rapid global delivery to protect your manufacturing line from supply chain volatility.

Applications of ADI AD7674ASTZ
Thanks to its combination of high bit depth, fast throughput, and adaptive power modes, the AD7674ASTZ is widely utilized across demanding industrial and medical systems:
Medical Equipment: Front-end processing units in Computed Tomography (CT) scanners and advanced multi-channel diagnostic instrumentation.
High Dynamic Data Acquisition: High-speed multi-channel data systems requiring synchronized telemetry without latency penalties.
Geophysical Sensing: Geophone and hydrophone sensor arrays where low standby power and broad dynamic range are critical.
Sigma-Delta Replacement: Replaces power-intensive Sigma-Delta ADCs in multi-channel applications due to its power savings at lower throughput rates.
Precision Instrumentation: Automated test equipment (ATE), spectrum analyzers, and laboratory chemical monitors.

Why Source AD7674ASTZ from Perceptive Components?
Sourcing precision semiconductors requires an independent distributor who can balance technical support with supply chain security. Perceptive Components provides critical advantages for global B2B buyers:
Inventory Stability: We hold massive stock allocations for both active production lines and hard-to-find or end-of-life (EOL) components.
Quality Assurance: Our rigorous incoming inspection and tier-one screening processes guarantee 100% genuine, factory-authentic parts.
Global Logistics: Our specialized international logistics network guarantees fast, trackable shipping directly to production facilities in North America, Europe, and Asia.
Competitive Pricing: Through our global direct-sourcing framework, we eliminate multiple middle-tier markups to deliver the best market price for the AD7674ASTZ.
Recommended Alternatives & Drop-In Replacements of AD7674ASTZ
If you are managing long lead times or encountering strict manufacturer allocations, the Analog Devices PulSAR family offers several layout-compatible cross-references:
AD7676ASTZ: A pin-to-pin compatible 16-bit alternative supporting up to 500 kSPS, suitable if your DSP can accept a minor bit-depth reduction.
AD7678ASTZ: An 18-bit footprint-compatible alternative optimized for lower sample rates (100 kSPS to 250 kSPS), ideal if maximum warp speeds are not required.
AD7679ASTZ: A direct upgrade pathway offering 18-bit resolution at 570 kSPS, serving as an excellent drop-in option with optimized power dissipation.
If you are facing lead time issues with factory allocations, contact Perceptive Components for our engineering team's certified drop-in replacements.
