HT82V26A General Description

The HT82V26A 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 HT82V26A operates from a single 5V power supply, typically consumes 400mW of power.

HT82V26A Maximum Ratings

Supply Voltage ......................V_SS-0.3V to V_SS+5.5V

HT82V731 General Description

HT82V731 is a 16-bit digital-to-analog converter IC utilizing CMOS technology specially designed for stereo audio application.

HT82V731 converts the 16 bits serial data into an analog output voltage. The digital data is internally converted to floating point expression whose format consists of 10 bits mantissa and 7step exponent. Using an R-string voltage divider, this floating point expression data is then converted to analog voltage.

It is compatible with TDA1311. It is available in 8-pin SOP package.

HT82V731 Features

· CMOS technology
· Low power consumption
· Two voltage output channel in the same chip
· 16-bit dynamic range
· Low total harmonic distortion
· 5 voltage single power supply
· 8-pin SOP package

HT82V731 Typical Application

· Digital audio equipment
· CD ROM/VCD
· MPEG card
