Description

The

MCP33131D/MCP33121D/MCP33111D-10

and

MCP33131D/MCP33121D/MCP33111D-05

are

fully-differential 16, 14, and 12-bit, single-channel

1 Msps and 500 kSPS ADC family devices,

respectively, featuring low power consumption and

high performance, using a successive approximation

register (SAR) architecture.

The device operates with a 2.5V to 5.1V external

reference (V

REF

), which supports a wide range of input

full-scale range from -V

REF

to +V

REF

. The reference

voltage setting is independent of the analog supply

voltage (AV

DD

) and is higher than AV

DD.

The

conversion output is available through an easy-to-use

simple SPI- compatible 3-wire interface.

The device requires a 1.8V analog supply voltage

(AV

DD

) and a 1.7V to 5.5V digital I/O interface supply

voltage (DV

IO

). The wide digital I/O interface supply

(DV

IO

) range (1.7V – 5.5V) allows the device to

interface with most host devices (Master) available in

the current industry such as the PIC32

microcontrollers, without using external voltage level

shifters.

When the device is first powered-up, it performs a

self-calibration to minimize offset, gain and linearity

errors. The device performance stays stable across the

specified temperature range. However, when extreme

changes in the operating environment, such as in the

reference voltage, are made with respect to the initial

conditions (e.g. the reference voltage was not fully

settled during the initial power-up sequence), the user

may send a recalibrate command anytime to initiate

another

self-calibration

to

restore

optimum

performance.

When the initial power-up sequence is completed, the

device enters a low-current input acquisition mode,

where sampling capacitors are connected to the input

pins. This mode is called Standby.

During Standby, most of the internal analog circuitry is

shutdown in order to reduce current consumption.

Typically, the device consumes less than 1 µA during

Standby. A new conversion is started on the rising edge

of CNVST. When the conversion is complete and the

host lowers CNVST, the output data is presented on

SDO, and the device enters Standby to begin acquiring

the next input sample. The user can clock out the ADC

output data using the SPI-compatible serial clock

during Standby.

The ADC system clock is generated by the internal

on-chip clock, therefore the conversion is performed

independent of the SPI serial clock (SCLK).

This device can be used for various high-speed and

high-accuracy analog-to-digital data conversion

applications, where design simplicity, low power, and

no output latency are needed.

The device is AEC-Q100 qualified for automotive appli-

cations and operates over the extended temperature

range of -40°C to +125°C. The available package

options are Pb-free small 3 mm x 3 mm TDFN-10 and

MSOP-10.
