AD9814KRRL

Overview

The AD9814KRRL is a complete 14-bit CCD/CIS signal processor manufactured by Analog Devices Inc. It features a 3-channel architecture designed to sample and condition outputs from trilinear color CCD arrays, supporting operation up to 10 MSPS in 3-channel mode and 7 MSPS in 1-channel mode. The device integrates Correlated Double Sampling (CDS), a 14-bit ADC with no missing codes guaranteed, and Programmable Gain Amplifiers (PGA) with 64 steps of gain adjustment. It operates on a single +5 V supply, consuming typically 330 mW, and is housed in a 28-lead SOIC package.

Feature Summary

• Integrates three independent channels for simultaneous processing of red, green, and blue signals from imaging sensors.
• Includes internal Correlated Double Sampling circuitry to reduce noise and offset errors in CCD applications.
• Provides programmable gain amplification with 64 discrete steps and adjustable offset correction for each channel.
• Features a multiplexed byte-wide digital output interface accessible via a standard 3-wire serial control bus.

Applications

• Flatbed document scanners
• Film scanners
• Digital color copiers
• Multifunction peripherals

Procurement Notes

Verify the specific suffix 'RRL' indicates tape and reel packaging when sourcing components. Confirm that the K-grade temperature range meets the operational requirements of the target environment. Check current availability status as this component may be subject to discontinuation or limited stock conditions.

Selection Notes

Select the AD9814KRRL for applications requiring high-resolution analog signal conditioning for trilinear CCD sensors. Ensure the system design accommodates the 28-lead SOIC footprint and provides adequate decoupling for the AVDD and DRVDD supplies. Verify that the host controller supports the required serial interface timing specifications for reliable register configuration.

Part Context

The AD9814 series serves as an analog front-end solution for imaging systems, bridging sensor outputs to digital processing units. The KRRL variant specifically denotes the commercial temperature grade packaged in a reel format, distinguishing it from the JR version which may have different packaging or qualification standards within the same functional family.

Replacement Considerations
