New Successive Approximation Register (SAR) Analog-to-Digital Converters

Microchip announced 12 new SAR ADCs along with a companion differential amplifier. Designed to operate in high temperatures and high electromagnetic environments, the MCP331x1(D)-xx family includes the industry’s only one million samples per second (Msps) fully AEC-Q100-qualified 16-bit SAR, providing the reliability required for automotive and industrial applications. The MCP6D11 differential amplifier provides a low-distortion, high-accuracy interface to achieve the full performance of the ADC within systems.
