www.DataSheet4U.com MCP3425 16-Bit Analog-to-Digital Converter with I2C Interface and On-Board Reference Features 16-bit ΔΣ ADC in a SOT-23-6 package Differential Input Operation 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 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 - 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 Description 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. The MCP3425 device performs conversion at rates of 15, 60, or 240 samples per second (SPS) depending on the user controllable configuration...
