A/D, D/C Converters for Image Signal Processing
MN655431SH
Low Power 8-Bit CMOS A/D Converter for Image Processing
Overview
The MN655431SH is an 8-bit CMOS analog-to-digital
converter with a maximum conversion rate of 15 MSPS.
It uses a half flash structure based on chopper comparators and achieves both high speed and low power consumption with multiplex processing.
It provides separate power supply pins for the circuits
driving the low-voltage digital output pins.
Features
Maximum conversion rate: 15 MSPS (min.)
Linearity error: ±0.5 LSB (typ.)
Differential linearity error: ±0.4 LSB (typ.)
Power supply voltage: 4.40 to 5.25 V
Power consumption: 90 mW (typ.)
Applications
Digital television receivers
Digital video equipment
Digital image processing equipment
