AD7994BRUZ-1 Datasheet PDF - ADI

●The AD7994BRUZ-1 is a 4-channel 12-bit low power successive approximation Analog-to-digital Converter (ADC) with an I²C-compatible interface. The part operates from a single 2.7 to 5.5V power supply and feature a 2µs conversion time. The parts contain a multiplexer and track-and-hold amplifier that can handle input frequencies up to 11MHz. It provides a 2-wire serial interface that is compatible with I²C interfaces. It normally remains 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. It requires an external reference that should be applied to the REFIN pin and can be in the range of 1.2 to VDD. This allows the widest dynamic input range to the ADC.
