HT82V14 General Description

The HT82V14 is a complete analog signal processor for CCD imaging applications. It features a 3-channel architecture designed to sample and condition the outputs of the trilinear color CCD arrays. Each channel consists of an input clamp, Correlated Double Sampler (CDS), offset DAC and Programmable Gain Amplifier (PGA), multiplexed to a high performance 14-bit A/D converter.

The CDS amplifiers may be disabled for use with sensors such as Contact Image Sensors (CIS) and CMOS active pixel sensors, which do not require CDS.

The 14-bit digital output is multiplexed into an 8-bit output word that is accessed using two read cycles. The internal registers are programmed through a 3-wire serial interface, which provides gain, offset, and operating mode adjustments.

HT82V14 Maximum Ratings

Supply Voltage ..........................-0.3V to 5.5V
Storage Temperature ....................0 to 70
Input Voltage ...............V_SS-0.3V to V_DD+0.3V

HT82V26 General Description

The HT82V26 is a complete analog signal processor for CCD imaging applications. It features a 3-channel architecture designed to sample and condition the outputs of tri-linear color CCD arrays. Each channel consists of an input clamp, Correlated Double Sampler (CDS), offset DAC and Programmable Gain Amplifier (PGA), and a high performance 16-bit A/D converter.

The CDS amplifiers may be disabled for use with sensors such as Contact Image Sensors (CIS) and CMOS active pixel sensors, which do not require CDS. The 16-bit digital output is multiplexed into an 8-bit output word that is accessed using two read cycles. The internal registers are programmed through a 3-wire serial interface, which provides gain, offset and operating mode adjustments.

The HT82V26 operates from a single 5V power supply, typically consumes 400mW of power.

HT82V26 Maximum Ratings

Supply Voltage .........................V_SS-0.3V to V_SS+5.5V
Input Voltage ...........................V_SS-0.3V to V_DD+0.3V
Storage Temperature ...........................-50 to 125
Operating Temperature ..........................-25 to 75

Note: These are stress ratings only. Stresses exceeding the range specified under "Absolute Maximum Ratings" may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.
