Analog Devices AD7998BRUZ-0 AD7998BRUZ-0 ADC 12BIT 188KSPS TSSOP-20
AD7998 is an 8-channel, low power, successive approximation ADC with an I²C-compatible interface. It provides a 2-wire serial interface that is compatible with I²C interface. 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, out-of 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.
