Microchip Technology MCP3428
the MCP3428 has four differential input channels. These devices can output analog-to-digital conversion results at rates of 15 (16-bit mode), 60 (14-bit mode), or 240 (12-bit mode) samples per second depending on the user controllable configuration bit settings using the two-wire I2C serial interface. This provides accurate conversion results from conversion to conversion over variations in temperature and power supply fluctuation.| Part No. | MCP3428 |
