General Description

The MCP3461/2/4R devices are 2/4/8-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 voltage reference,

internal oscillator, temperature sensor and burnout

sensor detection, in order to reduce system component

count and total solution cost.

The MCP3461/2/4R 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 16-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 MCP3461/2/4R devices are available in a leaded

20-lead TSSOP package, as well as in an ultra-small,

3 mm x 3 mm x 0.55 mm 20-lead UQFN package and

are specified over an extended temperature range from

-40°C to +125°C.

Applications

• Precision Sensor Transducers and Transmitters:

Pressure, Strain, Flow and Force Measurement

• Factory Automation and Process Controls

• Portable Instrumentation

• Temperature Measurements
