AD9806KSTZRL

Overview

The AD9806KSTZRL is a complete analog signal processor for CCD applications, featuring an 18 MHz single-channel architecture. It samples and conditions outputs from interlaced and progressive scan area CCD arrays. The signal chain includes an input clamp, correlated double sampler (CDS), digitally programmable gain amplifier (PGA), black level clamp, and a 10-bit A/D converter. It operates from a single 3 V supply with typical power consumption of 75 mW at 3.0 V. The device provides a 3-wire serial interface for programming gain, black level, input configuration, and power-down modes. It is housed in a 48-lead LQFP package and rated for operation between –20°C and +85°C.

Feature Summary

• Integrates a 10-bit 18 MSPS ADC with a low noise PGA offering 0 dB to 34 dB gain range.
• Includes two auxiliary 8-bit DACs and multiple input modes for analog video processing.
• Features pin-compatible design with industry standard AD9803 for easy migration.

Applications

• Camcorders (8 mm and DVC)
• Digital Still Cameras

Procurement Notes

Verify the specific ordering suffix KSTZRL against the manufacturer's current datasheet to confirm the exact temperature grade and tape-and-reel packaging details. Ensure the procurement source provides valid traceability documentation. Confirm that the component meets RoHS compliance standards as specified in the official product documentation before finalizing purchase orders.

Selection Notes

Select this component when designing systems requiring a single-chip solution for CCD signal conditioning with integrated digitization. Consider the 10-bit resolution and 18 MHz sampling rate for appropriate image quality requirements. Evaluate the power consumption specifications against system battery life constraints, noting the availability of power-down modes. Verify compatibility with existing CCD sensor output characteristics and timing requirements.

Part Context

The AD9806 is part of Analog Devices' family of imaging signal processors designed specifically for CCD applications. It serves as a direct replacement or upgrade path for designs previously using the AD9803, maintaining pin compatibility while offering enhanced features such as higher resolution ADC and additional programmable inputs. This positioning allows designers to integrate complex signal processing functions into a compact footprint.

Replacement Considerations

The AD9806 is pin-compatible with the AD9803. Designers migrating from AD9803 should verify register configurations and timing parameters, as functional differences exist despite physical compatibility. No other direct substitute part numbers are documented in the provided source material.
