AD7998BRUZ-0, 12-бит АЦП TSSOP20

The AD7998BRUZ-0 is a 8-channel 12-bit Analogue to Digital Converter (ADC) with I?C 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 I?C interface. Each part comes in two versions and each version allows for at least two different I?C addresses. Both versions support standard and fast I?C 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 I?C 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.
