AD9847AKSTZRL

Overview

The AD9847AKSTZRL is a 10-bit CCD signal processor with an integrated timing driver, manufactured by Analog Devices Inc. It operates within a temperature range of -20°C to +85°C and is housed in a 48-lead LQFP package. The device supports a maximum clock rate of 40 MHz and includes a 10-bit A/D converter with a full-scale input voltage of 2.0 V. Power supply voltages include 2.7 V to 3.6 V for analog supplies (AVDD) and 3.0 V to 5.5 V for digital supplies (DVDD). Total power dissipation at 3 V and 40 MSPS is 200 mW.

Feature Summary

• Includes a Correlated Double Sampler (CDS), Pixel Gain Amplifier (PxGA), Variable Gain Amplifier (VGA), and black level clamp.
• Features a Precision Timing core that allows adjustment of high-speed clocks with approximately 500 ps resolution at 40 MHz.
• Provides complete on-chip timing drivers for RG and H1–H4 horizontal clocks, supporting direct connection to the CCD.

Applications

• Digital Still Cameras

Procurement Notes

Verify the specific suffix RL against official documentation to confirm reel packaging and ensure compatibility with automated assembly processes. Confirm current availability status as distribution channels may list discontinued or limited stock items. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component for applications requiring a highly integrated CCD signal processor with precise timing control. Ensure the system design accommodates the specified voltage ranges for analog and digital supplies. Verify that the 40 MHz pixel rate aligns with the target CCD sensor specifications and that the 48-lead LQFP package fits the PCB layout constraints.

Part Context

The AD9847 is part of Analog Devices' family of CCD signal processors designed for digital imaging applications. It integrates the analog front end and timing generation into a single chip, reducing system complexity. The AKSTZRL designation indicates the industrial temperature grade, LQFP package, and reel packaging format.

Replacement Considerations

The AD9849AKSTZRL is a compatible alternative offering 12-bit resolution. Verify pinout compatibility and register mapping differences when substituting. Ensure the application can accommodate the higher bit depth and any changes in power consumption or timing characteristics.
