The AD7998BRUZ-0 is a 8-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 8-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 and fast I²C interface modes. ADC normally remains in a shutdown state while not converting and power up only for conversions. The conversion process can be controlled by 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.
● 12-bit ADC with 2µs typical fast conversion time
● 8 Single-ended analogue input channels
● Low power consumption
● Sequencer operation
● Automatic cycle interval mode
● Out-of-range indicator/alert function
● Pin-selectable addressing via AS
●ESD sensitive device, take proper precaution while handling the device.
