Microchip Technology Inc. announced 12 new Successive Approximation Register (SAR) Analog-to-Digital Converters (ADCs) along with a companion differential amplifier designed specifically for the new portfolio of SAR ADCs. 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.
The MCP331x1(D)-xx family ranges in resolution from 12-, 14- and 16-bit, with speed options ranging from 500 kilosamples per second (ksps) to 1 Msps, allowing developers to choose the right ADC for their designs. A fixed low analog supply voltage (AVDD) of 1.8V and low-current operation (1.6 mA typical active current for 1 Msps and 1.4 mA for 500 ksps) enables this family of ADCs to have an ultra-low power consumption, while maintaining a wide input full-scale range.
