General Description

The MCP3561/2/4 devices are 2/4/8-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, tem-

perature sensor and burnout sensor detection, in order

to reduce system component count and total solution

cost.

The MCP3561/2/4 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 config-

uration 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 24/32-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 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-20 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
