Product Details
Key Features
Applications

The AD4190-4 is a low noise, completely integrated analog front end for high precision measurement applications. The device contains a low noise, 24-bit Σ-Δ analog-to-digital converter (ADC) and can be configured to have four differential or eight single-ended or pseudodifferential inputs. The on-chip low-noise gain stage ensures that signals of small amplitude can be interfaced directly to the ADC.The AD4190-4 offers the highest degree of signal chain integration. The device contains an internal reference and accepts two external differential references, which can be internally buffered. Other key integrated features include:

  • Programmable gain amplifier (PGA). Due to the programmable gain (0.5 to 128), the PGA allows direct interfacing to transducers with low output amplitudes such as resistive bridges, thermocouples, and resistance temperature detectors (RTDs).
  • The PGA has a wide common-mode input range, which gives designers a greater margin for widely varying input common modes.
  • Low drift, well matched precision current sources. Use the excitation current sources to excite 2-, 3-, and 4-wire RTDs or bridge type sensors. Excitation current output options include 10μA, 50μA, 100μA, 250μA, 500μA, 1mA, and 1.5mA. The currents can also be added if higher currents are required.
  • Use the low-side power switch (PDSW) to power down bridge sensors between conversions.
  • Voltage bias for thermocouples (the VBIAS source sets the common-mode voltage of a channel to (AVDD + AVSS)/2.
  • The smart sequencer allows the conversion of each enabled preconfigured channel in a predetermined order, which allows a mix of transducer, system checks, and diagnostic measurements to be interleaved. The sequencer eliminates the need for repetitive serial interface communication with the device to change configuration. Configure the 16-channels in the sequence. Each of these channels selects from eight user-defined ADC setups that allow selection of gain, filter type, output data rate, buffering, and reference source.

    Shipping & Availability
    Payment

    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 AD4190-4, and what package does it use?

    AD4190-4 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 AD4190-4 datasheet above.

    Why is dynamic quotation used instead of a fixed price for AD4190-4?

    Electronic component spot-market pricing for AD4190-4 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 AD4190-4?

    Lead times for AD4190-4 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.
