GENERAL DESCRIPTION
The ADC-318 and ADC-318A are 8 bit monolithic bipolar,
full flash A/D converters. Though they have high, 120MHz
(ADC-318) and 140MHz (ADC-318A), sampling rates, their
input logic level, including the start convert pulse, is TTL,
ECL and PECL compatible. Digital outputs are also TTL
compatible and allow a straight output or a programmable
1:2 de-multiplexed output.
The ADC-318 and ADC-318A feature ±1/2 LSB max.
integral and differential non-linearity, +5V single or ±5V dual
power supply operation, a low 960mW maximum power
dissipation, 150MHz wide analog input range and excellent
temperature coefficient in a small 48 pin QFP package. The
start convert pulse can have a 50% duty cycle.
The ADC-318 and ADC-318A offer low cost, easy to use
functionality for design engineers.
