General Description

The MCP3465R is a one differential channel or two

single-ended channels, 16-Bit Delta-Sigma Analog-

to-Digital Converter (ADC) with a programmable data

rate of up to 153.6 ksps. It offers 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 MCP3465R ADC is fully configurable with an Over-

sampling Ratio (OSR) from 32 to 98304 and gain from

1/3x to 64x. The device includes 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.

The device comes 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 MCP3465R device is available in an ultra-small,

2 mm x 2 mm x 0.55 mm 12-Lead UQFN package and

is 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
