●The MCP3425A0T-E/CH is a low power, 16bit delta sigma analogue to digital converter (ADC) in 6 pin SOT-23 package. The onboard precision 2.048V reference voltage enables an input range of ±2.048V differentially. The MCP3425 device performs conversion at rates of 15, 60 or 240 samples per second (SPS) depending on user controllable configuration bit settings using two wire I2C serial interface. The MCP3425 contains an onboard voltage reference (2.048V), programmable gain amplifier (PGA) and internal oscillator. The user can select PGA gain of x1, x2, x4 or x8 before analogue to digital conversion takes place. This allows MCP3425 device to convert a smaller input signal with high resolution. This can be operated in continuous conversion or one shot conversion mode. The MCP3425 device can be used for various high accuracy analogue to digital data conversion applications where design simplicity, low power and small footprint are major considerations.
