ASD0322

250 MSPS, 8-bit Analog-to-Digital Converter

Description

Not recommended for new designs

The ASD0322 is a high-speed, 8-bit analog-to-digital converter implemented in an advanced BiCMOS process. It is a performance-enhanced version of the ASD0321, offering better linearity and dynamic performance with only slightly increased power dissipation. An advanced folding and interpolating architecture provides both a high conversion rate and low power dissipation of 425mW. The analog inputs can be operated in either single-ended or differential input mode. A 2.5V common mode reference is provided on chip for the single-ended input mode to minimize external components.
