Reference Voltage (VRT) +2.7 to +AVS VoltsDescriptionThe 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.
