FEATURES

• Low power dissipation (960mW max.)

• TTL compatible output

• Diff./Integral nonlinearity (±½LSB max.)

• 1:2 Demultiplexed straight output programmable

• 2:1 Frequency divided TTL clock output with reset

• Surface mount package

• Selectable Input Logic (TTl, ECL, PECL)

• +5V or ±5V Power Supply Operation

GENERAL DESCRIPTION

The ADC-318 and ADC-318A are 8 bit monolithic bipolar,

full ﬂ ash 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 coefﬁ cient 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.
