The AD7998BRUZ-1 is a 8-channel 12-bit low power successive approximation Analog-to-digital Converter (ADC) with an I²C-compatible interface. The parts operate from a single 2.7 to 5.5V power supply and features a 2µs conversion time. The parts contain an 8-channel multiplexer and track-and-hold amplifier that can handle input frequencies up to 11MHz. The AD7998 provides a 2-wire serial interface that is compatible with I²C interfaces. Each part comes in two versions, each version allows at least two different I²C addresses. The I²C interface on the AD7998-1 supports standard, fast and high speed I²C interface modes. The AD7998 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.
● 12-bit ADC with fast conversion time of 2µs typical
● 8 Single-ended analog input channels
