Product Details
Key Features
Documentation

The AD7457 is a 12-bit, low power, successive-approximation (SAR) analog-to-digital converter that features a pseudo differential analog input. This part operates from a single 2.7 V to 5.25 V power supply and features throughput rates up to 100 kSPS.The part contains a low-noise, wide bandwidth, differential track and hold amplifier (T/H) which can handle input frequencies in excess of 1 MHz. The reference voltage for the AD7457 is applied externally to the VREFpin and can range from 100mV to VDD, depending on what suits the application.The conversion process and data acquisition are controlled using CS and the serial clock allowing the device to interface with Microprocessors or DSPs.The AD7457 uses advanced design techniques to achieve very low power dissipation.PRODUCT HIGHLIGHTS

  • Operation with 2.7 V to 5.25 V power supplies.
  • Low power consumption. With a 3 V supply, the AD7457 offers 0.9 mW maximum power consumption for a 100 kSPS throughput rate.
  • Pseudo differential analog input.
  • Flexible power/serial clock speed management. The conversion rate is determined by the serial clock, allowing the power to be reduced as the conversion time is reduced through the serial clock speed increase. Automatic power-down after conversion allows the average power consumption to be reduced.
  • Variable voltage reference input.
  • No pipeline delays.
  • Accurate control of the sampling instant via the CS input and once-off conversion control.
  • ENOB > 10 bits typically with 500 mV reference.
  • Certified Quality & Compliance

    YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.

    • 1. Certification Scope: Quality certifications apply only to the entities, sites and activities listed in valid certificates. Management system certification does not certify each individual product.
    • 2. Product Authenticity: Products must match the agreed manufacturer, part number and condition. Supplier screening and authenticity checks help reduce counterfeit risk.
    • 3. Inspection & Testing: The inspection scope follows product risks and agreed requirements. Additional testing, laboratory arrangements, costs and lead times require written confirmation.
    • 4. Traceability & Documentation: Request conformity certificates, traceability records or test reports before ordering. Document availability, issuer and coverage must be confirmed for the offered goods.
    • 5. Environmental Compliance: RoHS and REACH information is based on applicable manufacturer documentation. Confirm the exact part, declaration date and relevant exemptions before ordering.
    • 6. Handling & Protection: Handling, storage and packaging follow applicable product requirements, including ESD and moisture protection where required. Special handling requirements must be agreed before ordering.

    Product FAQ
    Purchasing FAQ

    What type of component is AD7457, and what package does it use?

    AD7457 is an authentic electronic component manufactured by Analog Devices, categorized under Data Converter ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official AD7457 datasheet above.

    Why is dynamic quotation used instead of a fixed price for AD7457?

    Electronic component spot-market pricing for AD7457 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.

    What is the delivery timeline after placing an order for AD7457?

    Lead times for AD7457 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
