All new range of Successive Approximation Register ADCs

Microchip launched 12 new Successive Approximation Register (SAR) MCP331x1(D)-xx ADCs (Analog-to-Digital Converters) Family includes the 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. Microchip also launched differential amplifier MCP6D11 series designed specifically for the new portfolio of SAR ADCs. The MCP331x1(D)-xx family comes in different ranges in resolution from 12-, 14- and 16-bit.

MCP331x1(D)-xx family support a wide digital I/O interface voltage (DVIO) range (1.7V - 5.5V) which allows it to interface with most host devices, including Microchip’s PIC32, AVR and Arm-based microcontrollers and microprocessors. This eliminates the need for using external voltage level shifters. The ADCs comes with 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). This feature enables the ADCs to have an ultra-low power consumption, while maintaining wide input-full scale range.

Microchip also confirmed the availability of MCP331x1D-XX Evaluation Kit to demonstrate the performance of the MCP331x1D-XX SAR ADC family devices. MCP331x1D Evaluation Board, PIC32MZ EF MCU Curiosity Board for data collection, SAR ADC Utility PC Graphical User Interface (GUI) are the evaluation kit for these ADCs.

 

Pricing and Availability

Pricing for the new SAR ADCS range from the MCP33111 available for $1.45 each in 10,000-unit quantities to the MCP33131 available for $4.65 each in 10,000-unit quantities.  

Each MCP331x1(D)-xx  ADC is available in either the 10-MSOP with leads in a 3 mm X 3 mm package or 10-TDFN no leads 3 mm X 3 mm package. The 9 mm2 size is the smallest footprint available in the market for a 16-bit, 1 Msps differential ADC.

Pricing for the MCP6D11 is $1.17 in 10,000-unit quantities and is available in the 8-MSOP or 3 mm x 3 mm 16-QFN package. The MCP331x1(D)-xx Evaluation Kit is available for $175.
