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 conversion  
modes: (a) Continuous mode and (b) One-Shot mode.  
In One-Shot mode, the device enters a low current  
standby mode automatically after one conversion. This  
reduces current consumption greatly during idle peri-  
ods.  
• 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  
(VDD= 3V, Continuous Conversion)  
• One-Shot Conversion (1 SPS) with VDD = 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
