Monolithic Linear IC

LA7265W

Single-Chip Black and White CCD Camera

Signal Processing IC

Overview

The LA7265W is a single-chip IC that provides the signal processing required by black and white CCD cameras. This IC is optimal for surveillance cameras, door intercom cameras, and personal computer input cameras due to its ultraminiature package, low current drain, wide dynamic range, and high AGC gain.

Functions

•CCD clamping

•CDS (built-in S/H capacitor)

•IRIS amplifier

•AGC backlight correction

•S-curve gamma correction

•Aperture correction

•Variable setup

•Sync addition

•CCD clipping

•IRIS window

•AGC amplifier

•Gamma correction (0.45, 1.0 and variable)

•1H interpolation switch

•Aperture low illumination suppression

•Variable W.C.

•75 Ω drivers

Features

•CCD clamping used to provide a wide dynamic range: The LA7265W can handle a 1.5 Vp-p CCD signal data level.

•Reduced sampling noise provided by a built-in CDS capacitor.

•Variable AGC gain: up to a maximum of 32 dB.

•Backlight correction provided by weighting the iris and AGC levels.

•Three different gamma correction circuits, including S- curve gamma correction

•Knee characteristics are added to the gamma correction to prevent incorrect white rendering in low light situations.

•Automatic aperture adjustment according to the brightness

•Reduced current drain (under 40 mA)

•Ultraminiature package (SQFP48)

•Reduced external component count (50% as compared to the earlier Sanyo LA7261M)

•Reduced number of adjustment points (two points)

Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft’s control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO products described or contained herein.
