Panasonic MN6577F, MN6577H Datasheet
A/D, D/C Converters for Image Signal Processing
MN6577F, MN6577H
Low Power 10-Bit 3-Volt CMOS A/D Converters for Image Processing
Overview
The MN6577F and MN6577H are high-speed 10-bit
CMOS analog-to-digital converters for image processing applications.
They use a half flash structure based on chopper comparators to achieve both high speed and low power consumption, and operate on a single 3 volt power supply.
Features
Maximum conversion rate: 15 MSPS (min.)
Linearity error: ±1.3 LSB (typ.)
Differential linearity error: ±0.5 LSB (typ.)
Power supply voltage: 3.0 V
Power consumption: 40 mW (typ.) (f
=15 MHz)
CLK
Applications
Digital television
Digital video equipment
Digital image processing equipment
