AD7994BRUZ-1

AD7994 is a 4-channel, 12bit, low power, successive approximation ADC with an I²C-compatible interface. This device provide a 2-wire serial interface that is compatible with I²C interfaces. This device normally remain in a shutdown state while not converting, and power up only for conversions. The conversion process can be controlled using the CONVST pin, 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, and an open-drain, cut-off range indicator output (ALERT) becomes active when the programmed high or low limits are violated by the conversion result. This output can be used as an interrupt.
