TLV990-13PFB

The TLV990-13PFB from Texas Instruments is a single-chip CCD analog front-end designed for digital still camera and PC camera applications. This device integrates a 10-bit, 13 MSPS analog-to-digital converter (ADC) and performs essential analog processing functions to maximize dynamic range and correct sensor errors.

Key electrical specifications include a 10-bit resolution and a maximum sample rate of 13 MSPS. It features a programmable gain amplifier (PGA) with a gain range from 0 dB to 36 dB, adjustable in 0.045 dB steps. The device operates from a single 3-V supply (2.7V to 3.3V) and offers low power consumption, typically 150 mW during normal operation and only 2 mW in power-down mode. Typical differential nonlinearity error is less than ±0.5 LSB, and integral nonlinearity error is less than ±0.9 LSB.

The TLV990-13PFB includes features such as automatic or programmable optical black level and offset calibration with a digital filter and bad pixel limits. It also provides additional DACs for external analog setting and a serial interface for register configuration. Internal reference voltages are included.

Packaged in a 48-pin TQFP, the TLV990-13PFB is designed for surface mount applications. It operates within a temperature range of -20°C to 75°C.
