Panasonic MN65752H Datasheet
A/D, D/C Converters for Image Signal Processing
MN65752H
Low Power 8-Bit, 2-Channel CMOS A/D Converter for Image Processing
Overview
The MN65752H is an 8-bit, 2-channel CMOS analog-
to-digital converter for image processing applications.
It uses a half flash structure based on chopper comparators and achieves both high speed and low power
consumption with multiplexing.
It provides separate power supply pins for the circuits
driving the low-voltage digital output pins.
Features
Maximum conversion rate: 20 MSPS (min.)
Linearity error: ±0.9 LSB (typ.)
Differential linearity error: ±0.5 LSB (typ.)
Power supply voltage: 3.6 V or 2.6 V
Power consumption: 50 mW (typ.) (f
=16 MHz)
CLK
Applications
Digital television receivers
Digital video equipment
Digital image processing equipment
