Microchip TechnologyMCP3461-E/STA/D-W

The MCP3461R is a preferred, pin compatible option that should be used for new designs.

The MCP3461/2/4 devices are 1/2/4-channel, 16-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, in order to reduce system component count and total solution 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 come with a 20 MHz SPI-compatible serial interface. Communication is largely simplified with 8-bit commands, including various continuous Read/Write modes and 16/32-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 MCP3461/2/4 devices are available in a leaded 20-lead TSSOP package, as well as in an ultra-small 3 mm x 3 mm 20-lead UQFN package and are specified over an extended temperature range, from -40°C to +125°C
