DescriptionThe TLV986 is a highly integrated monolithic analog signal processor/digitizer designed to interface the area charge-coupled device (CCD) sensors in digital camera applications. The TLV986 performs all the analog processing functions necessary to maximize the dynamic range, corrects various errors associated with the CCD sensor, and then digitizes the results with an on-chip high-speed analog-to-digital converter (ADC). The key components of the TLV986 include: input clamp circuitry and a correlated double sampler (CDS), a programmable gain amplifier (PGA) with 0 to 36 dB gain range, two internal digital-to-analog converters (DAC) for automatic or programmable optical black level and offset calibration, a 10-bit, 12.5 MSPS pipeline ADC, a parallel data port for easy microprocessor interface, a serial port for configuring internal control registers, two additional DACs for external system control, and internal reference voltages.
Designed in advanced CMOS process, the TLV986 operates from a single 3-V power supply with a normal power consumption of 140 mW and a 2 mW power-down mode.
Single 3-V operation, low power consumption, and fully integrated analog processing circuitry make the TLV986 an ideal CCD sensor interfacing solution for the digital camera applications.
The part is available in a 48-pin TQFP package and is specified over 0 to 70 operating temperature range.
