Product Summary

The AD7998BRUZ0 is a 8-channel, 12-bit, low power, successive approximation ADC with an I2C-compatible interface. The AD7998BRUZ0 operates from a single 2.7 V to 5.5 V power supply and features a 2 μs conversion time. The parts contain an 8-channel multiplexer and track-and-hold amplifier that can handle input frequencies up to 11 MHz.The The AD7998BRUZ0 provides a 2-wire serial interface that is compatible with I2C interfaces. Each part comes in two versions, AD7997-0/AD7998-0 and AD7997-1/AD7998-1, and each version allows at least two different I2C addresses. The I2C interface on the AD7997-0/AD7998-0 supports standard and fast I2C interface modes. The I2C interface on the AD7997-1/ AD7998-1 supports standard, fast, and high speed I2C interface modes.
