Description

The MCP3426, MCP3427 and MCP3428 devices

(MCP3426/7/8) are the low noise and high accuracy

16 Bit Delta-Sigma Analog-to-Digital (ΔΣ A/D) Con-

verter family members of the MCP342X series from

Microchip Technology Inc. These devices can convert

analog inputs to digital codes with up to 16 bits of reso-

lution.

The MCP3426 and MCP3427 devices have two

differential input channels and the MCP3428 has four

differential input channels. All electrical properties of

these three devices are the same except the

differences in the number of input channels and I

address bit selection options.

These devices can output analog-to-digital conversion

results at rates of 15 (16-bit mode), 60 (14-bit mode), or

240 (12-bit mode) samples per second depending on

the user controllable configuration bit settings using the

two-wire I

C serial interface. During each conversion,

the device calibrates offset and gain errors

automatically. This provides accurate conversion

results from conversion to conversion over variations in

temperature and power supply fluctuation.

The device has an on-board 2.048V reference voltage,

which enables an input range of ± 2.048V differentially

(full scale range = 4.096/PGA).

The user can select the gain of the on-board

programmable gain amplifier (PGA) using the

configuration register bits (gain of x1, x2, x4, or x8).

This allows the MCP3426/7/8 devices to convert a very

weak input signal with high resolution.

The MCP3426/7/8 devices have two conversion

modes: (a) One-Shot Conversion mode and

(b) Continuous Conversion mode. In the One-Shot

conversion mode, the device performs a single

conversion and enters a low current standby

(shutdown) mode automatically until it receives another

conversion command. This reduces current

consumption greatly during idle periods. In continuous

conversion mode, the conversion takes place

continuously at the configured conversion speed. The

device updates its output buffer with the most recent

conversion data.

The devices operate from a single 2.7V to 5.5V power

supply and have a two-wire I

C compatible serial

interface for a standard (100 kHz), fast (400 kHz), or

high-speed (3.4 MHz) mode.

Typical Applications

• Portable Instrumentation and Consumer Goods

• Temperature Sensing with RTD, Thermistor, and

Thermocouple

• Bridge Sensing for Pressure, Strain, and Force

• Weigh Scales and Battery Fuel Gauges

• Factory Automation Equipment
