AD9895KBC

Overview

The AD9895KBC is a CCD signal processor featuring a 12-bit, 30 MHz A/D converter and a Precision Timing generator. It integrates a Correlated Double Sampler (CDS), Pixel Gain Amplifier (PxGA), Variable Gain Amplifier (VGA), and black level clamp. The device operates on a 3-wire serial interface and supports 2-phase and 4-phase H-clock modes with electronic and mechanical shutter control. Packaged in a 64-lead CSPBGA, it functions within an operating temperature range of –20°C to +85°C.

Feature Summary

• Integrates a complete analog front end with a 12-bit A/D converter for high-resolution signal processing.
• Includes a Precision Timing core providing 700 ps resolution for programmable high-speed clock generation.
• Features on-chip drivers for horizontal clocks and reset gate, eliminating external buffer requirements.

Applications

• Digital still cameras
• Digital video camcorders
• Industrial imaging systems

Procurement Notes

Verify the specific suffix KBC against the manufacturer's ordering guide to confirm the package type and temperature rating. Confirm that the component meets RoHS compliance standards required for the target assembly process. Ensure the supply voltage levels match the specified AVDD and DVDD ranges during system design validation.

Selection Notes

Select this model over the AD9891 when a 12-bit resolution and 30 MHz pixel rate are required. Verify compatibility with the target CCD sensor's output characteristics and timing requirements. Ensure the system can support the necessary power supply rails for the internal H-drivers and timing core.

Part Context

This component belongs to the AD9891/AD9895 family of CCD signal processors from Analog Devices. It shares the same functional architecture as the AD9891 but offers higher resolution and speed. The KBC suffix denotes the 64-lead CSPBGA package configuration suitable for space-constrained designs.

Replacement Considerations

The AD9891KBC is a lower-speed alternative within the same family. No other direct public substitutes are confirmed in the provided documentation.
