-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 ВµA typical
(VDD= 3V, Continuous Conversion) One-Shot Conversion (1 SPS) with VDD = 3V:
-9.7 ВµA typical with 16 bit mode
-2.4 ВµA typical with 14 bit mode
-0.6 ВµA 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: -40В°C to 125В°C The MCP3425 is a single channel low-noise, high
accuracy О”ОЈ 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 В±2.048V differentially
(О” 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. …
