The TC237 is a frame-transfer, charge-coupled device (CCD) image sensor
designed for use in single-chip black and white NTSC TV, computer, and
special-purpose applications requiring low cost and small size.
The image-sensing area of the TC237 is configured into 500 lines with 680 elements in each line. Twenty-two elements are provided in each line for dark reference. The blooming-protection feature of the sensor is based on an advanced lateral-overflow-drain concept. The sensor can be operated in a true-interlace mode as a 658(H) × 496(V) sensor with a very low dark current. One important feature of the TC237 very high-resolution sensor is the ability to capture a full 340,000 pixels per field. The image sensor also provides high-speed image-transfer capability. This capability allows for a continuous electronic exposure control without the loss of sensitivity and resolution inherent in other technologies. The charge is converted to signal voltage at 20 uV per electron by a high-performance structure with a reset and a voltage-reference generator. The signal is further buffered by a low-noise, two-stage, source-follower amplifier to provide high output-drive capability. The TC237 is built using TI-proprietary advanced virtual-phase (AVP) technology, which provides devices with high blue response, low dark signal, good uniformity, and single-phase clocking. The TC237 is characterized for operation from -10°C to 45°C. This MOS device contains limited built-in gate protection. 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 VSS. Under no circumstances should pin voltages exceed absolute maximum ratings. Avoid shorting OUT to VSS during operation to prevent damage to the amplifier. The device can also be damaged if the output terminals are reverse-biased and an excessive current is allowed to flow. 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. |
