The AD7994BRUZ-0 is a 4-channel 12-bit Analogue to Digital Converter (ADC) with I2C compatible interface that operates from a single 2.7 to 5.5V power supply and features a 2μs conversion time. The parts contain a 4-channel multiplexer and track-and-hold amplifier that can handle input frequencies up to 11MHz. It provides a 2-wire serial interface that is compatible I2C interface. Each part comes in two versions and each version allows for at least two different I2C addresses. Both versions support standard fast and high speed I2C interface modes. ADC normally remains in a shutdown state while not converting and power up only for conversions. The conversion process is controlled by a command mode where conversions occur across I2C write operations or an automatic conversion interval mode selected through software control. On-chip limit registers can be programmed with high and low limits for the conversion result.
