New SAR ADC enables high-speed analogue-to-digital conversion

Microchip has released 12 new SAR ADCs together with a companion differential amplifier created specifically for the new portfolio of SAR ADCs. Devised to operate in high temperatures and high electromagnetic environments, the MCP331x1(D)-xx family comprises the industry’s only 1Msps fully AEC-Q100-qualified 16-bit SAR, providing the reliability demanded for automotive and industrial applications. The MCP6D11 differential amplifier offers a low-distortion, high-accuracy interface to deliver the full performance of the ADC within systems. These devices support a broad digital I/O interface voltage (DVIO) range (1.7V-5.5V) which enables it to interface with most host devices, including the company's PIC32, AVR and Arm-based microcontrollers and microprocessors. This removes the need for external voltage level shifters. The family comprises both single-ended and differential input voltage measurement options, allowing systems to convert the difference between any two arbitrary waveforms. Perfect for applications including high-precision data acquisition, electric vehicle battery management, motor control and switch-mode power supplies, the AEC-Q100-qualified family offers reliable performance across harsh environments.
