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

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.
