描述 Description

The HD49343NP/HNP is a CMOS IC that provides CDS-PGA analog processing (CDS/PGA) suitable for CCD camera

digital signal processing systems together with a 12-bit A/D converter in a single chip.

Functions

? Correlated double sampling

? PGA

? Serial interface control

? 12-bit ADC

? Operates using only the 3 V, ADC output

? Corresponds to switching mode of power dissipation and operating frequency

HD49343HNP : 200 mW, f_max: 36 MHz

HD49343NP : 120 mW, f_max: 25 MHz

? QFN 36-pin package

特性 Features

? Suppresses the CCD reset noise by the correlated double sampling.

? High sensitivity can be achieved by 10 bit gray scale provided by PGA which can be set to –6 to 34 dB.

? PGA gain, S/H frequency response, pulse timing, etc., is achieved via a serial interface.

? High precision is provided by a 12-bit resolution A/D converter.

? Difference encoded gray code can be selected as an A/D output code. It is effective in suppression of solarization

(wave pattern). It is patented by Renesas.
