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)
