MCP3425

16-Bit Analog-to-Digital Converter

with I²C Interface and On-Board Reference

Features

Description

• 16-bit ΔΣ ADC in a SOT-23-6 package

• Differential Input Operation

The MCP3425 is a single channel low-noise, high

accuracy ΔΣ A/D converter with differential inputs and

up to 16 bits of resolution in a small SOT-23-6 package.

The on-board precision 2.048V reference voltage

enables an input range of ±2.048V differentially

(Δ voltage = 4.096V). The device uses a two-wire I²C

compatible serial interface and operates from a single

2.7V to 5.5V power supply.

• Self Calibration of Internal Offset and Gain per

each conversion

• On-Board Voltage Reference:

- Accuracy: 2.048V ± 0.05%

• On-Board Programmable Gain Amplifier (PGA):

- Gains of 1, 2, 4 or 8

The MCP3425 device performs conversion at rates of

15, 60, or 240 samples per second (SPS) depending

on the user controllable configuration bit settings using

the two-wire I²C serial interface. This device has an

on-board programmable gain amplifier (PGA). The

user can select the PGA gain of x1, x2, x4, or x8 before

the analog-to-digital conversion takes place. This

allows the MCP3425 device to convert a smaller input

signal with high resolution. The device has two conver-

sion modes: (a) Continuous mode and (b) One-Shot

mode. In One-Shot mode, the device enters a low

current standby mode automatically after one conver-

sion. This reduces current consumption greatly during

idle periods.

• On-Board Oscillator

• INL: 10 ppm of FSR (FSR = 4.096V/PGA)

• Programmable Data Rate Options:

- 15 SPS (16 bits)

- 60 SPS (14 bits)

- 240 SPS (12 bits)

• One-Shot or Continuous Conversion Options

• Low Current Consumption:

- 145 µA typical

(V_DD= 3V, Continuous Conversion)

• One-Shot Conversion (1 SPS) with V_DD= 3V:

- 9.7 µA typical with 16 bit mode

The MCP3425 device can be used for various high

accuracy analog-to-digital data conversion applications

where design simplicity, low power, and small footprint

are major considerations.

- 2.4 µA typical with 14 bit mode

- 0.6 µA typical with 12 bit mode

• Supports I²C Serial Interface:

- Standard, Fast and High-Speed Modes

• Single Supply Operation: 2.7V to 5.5V

• Extended Temperature Range: -40°C to 125°C
