The MCP346x family from Microchip Technology are 1/2/4-channel, 16-bit, Delta-Sigma analog-to-digital converters (ADCs) with a programmable data rate of up to 153.6 kSPS. They offer integrated features such as internal oscillator, temperature sensor, and burnout sensor detection to reduce system component count and total solution cost. These devices come with a 20 MHz SPI-compatible serial interface. Communication is largely simplified with 8-bit commands, including various continuous read/write modes and 16-bit/32-bit multiple data formats that can be accessed by the direct memory access (DMA) of an 8-bit, 16-bit, or 32-bit MCU.

The MCP3561/2/4 are 1/2/4-channel, 24-bit, Delta-Sigma analog-to-digital converters (ADCs), with programmable data rate of up to 153.6 kSPS. They offer integrated features such as internal oscillator, temperature sensor and burnout sensor detection which reduces the overall design cost. The MCP3461/2/4 ADCs are fully configurable with oversampling ratio (OSR) from 32 to 98304 and gain from 1/3X to 64X. These devices include an internal sequencer (SCAN mode) with multiple monitor channels and a 24-bit timer to be able to automatically create conversion loop sequences without needing MCU communications. Advanced security features such as CRC and register map lock can ensure configuration locking and integrity as well as communication data integrity for secure environments. These devices are rated to extended temperature range from -40°C to +125°C and are available in a 3 mm x 3 mm UQFN-20 package.
