description

The TL1051 is a bipolar monolithic integrated circuit designed for use in preprocessing three channels of TI CCD

image sensors. It receives video inputs from the TI TL1593 three-channel sample-and-hold circuit and outputs

three processed channel signals and a single multiplexed Y (luminance) signal. Processing functions of the

TL1051 include gain, automatic gain control, clamp, white balance, and white clip.

The TL1051 is supplied in a 44-pin surface-mount plastic package and is characterized for operation from – 20

°C

to 45

°C.

This device contains circuits to protect its inputs and outputs against damage due to high static voltages or electrostatic fields. These

circuits have been qualified to protect this device against electrostatic discharges (ESD) of up to 2 kV according to MIL-STD-883C,

Method 3015; however, precautions should be taken to avoid application of any voltage higher than maximum-rated voltages to these

high-impedance circuits. During storage or handling, the device leads should be shorted together or the device should be placed in

conductive foam. In a circuit, unused inputs should always be connected to an appropriate logic voltage level, preferably either VCC or ground.

Specific guidelines for handling devices of this type are contained in the publication

Guidelines for Handling Electrostatic-Discharge-Sensitive

(ESDS) Devices and Assemblies available from Texas Instruments.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
