AD9895KBCZ

Overview

The AD9895KBCZ is a highly integrated CCD signal processor featuring a complete analog front end and a programmable timing generator. It includes a 12-bit, 30 MHz A/D converter, Correlated Double Sampler (CDS), Pixel Gain Amplifier (PxGA), Variable Gain Amplifier (VGA), and black level clamp. The device utilizes a Precision Timing core with 1 ns resolution for high-speed clock generation. It operates on multiple supplies: AVDD/TCVDD/DVDD at 2.7 V to 3.6 V, and HVDD/RGVDD at 3.0 V to 5.25 V. The component is housed in a 64-lead CSPBGA package and supports an operating temperature range of –20°C to +85°C.

Feature Summary

• Integrates a 12-bit A/D converter with Correlated Double Sampling and dual-stage amplification including PxGA and VGA.
• Features a Precision Timing core capable of generating high-speed CCD clocks with fine edge resolution.
• Includes on-chip drivers for horizontal clocks and reset gate, supporting direct connection to CCD sensors.
• Configurable via a 3-wire serial interface for flexible system synchronization and timing control.

Applications

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

Procurement Notes

Verify the specific suffix KBCZ against the manufacturer's current ordering guide to confirm package option and temperature grade. Ensure compatibility with the required supply voltages and serial interface protocols before integration into the design.

Selection Notes

Select this model over the AD9891 when a 12-bit resolution and 30 MHz pixel rate are required. Confirm that the system can accommodate the multiple power supply rails and the external vertical driver requirement for the CCD sensor.

Part Context

This component belongs to the AD9891/AD9895 family of CCD signal processors. While functionally similar to the AD9891, it offers higher resolution and speed. Both share the same package and timing architecture but differ in ADC specifications and maximum clock rates.

Replacement Considerations

The AD9891KBCZ is a lower-performance alternative within the same family. No other direct substitutes are documented in the provided source material.
