Analog Devices Inc. AD9816JSRL

The AD9816 is a complete analog front end for imaging systems using a CCD or contact image sensor. Its red, green and blue input paths include clamp and correlated double-sampling circuitry, programmable offset DACs and gain amplifiers. A channel multiplexer feeds a 12-bit converter, while a three-wire serial interface selects operating mode, gain and offset.

The manufacturer describes a 44-lead metric MQFP, package option S-44, for AD9816JS. The database records AD9816JSRL as 44-QFP; the local package registry maps it to 44-QFP.jpg. Confirm that the JSRL suffix has the same package outline and review the S-44 drawing before PCB release.

Layout checks

• Match pin-one orientation and the metric S-44 lead geometry.
• Keep the CCD/CIS analog paths and coupling capacitors close to the device.
• Decouple analog, digital and output-driver supplies as shown in the application circuit.

The registered local package JPG is missing; the page must not be published until the image and footprint are reviewed.

The AD9816 datasheet identifies these 44-pin MQFP signal groups. Check the complete manufacturer pin diagram for orientation and unused pins.

PGAOUT_C and PGAOUT_T are evaluation monitor pins; the datasheet calls for leaving them unconnected during normal operation.

Electrical limits and timing assume the test conditions in the original AD9816 Rev. A datasheet. Confirm the exact JSRL order code with the supplier.

A replacement must be assessed for the sensor input range, CDS/SHA timing, PGA and offset programmability, reference levels, 12-bit output format, 6 MSPS throughput, supply domains, control interface and mechanical footprint. A newer CCD/CIS front end is not necessarily pin- or software-compatible.

No internal alternative-product link is shown because no electrically and mechanically verified replacement with a matching database URL was established.

Analog Devices published the AD9816 Rev. A datasheet as a complete 12-bit, 6 MSPS CCD/CIS signal processor. That document marks the product obsolete and lists AD9816JS in the 44-lead S-44 package. Obtain the exact AD9816JSRL order-code interpretation, traceability and lifecycle documentation from a qualified supplier.

Because the manufacturer marks this device obsolete, verify marking, package, lot traceability, storage and ESD handling for each offered lot. Existing catalog stock and price are not a confirmed current quotation; ask the supplier for exact-part availability and quantity-break prices before ordering.

Before using this legacy part, review the sensor waveform, CDS or SHA timing, input coupling, gain and offset registers, supply decoupling, 44-lead MQFP footprint and host interface. Missing package imagery, suffix confirmation and current stock/price verification prevent publication of this draft.
