The AD7992 is a 12-bit, low power, successive approximation ADC with an I2C-compatible interface. The part operates from a single 2.7 V to 5.5 V power supply and features a 2 μs conver-sion time. The part contains a 2-channel multiplexer and track-and-hold amplifier that can handle input frequencies up to 11 MHz.The AD7992 provides a 2-wire serial interface compatible with I2C interfaces. The part comes in two versions, the AD7992-0 and the AD7992-1, and each version allows for at least two different I2C addresses. The AD7992-0 supports standard and fast I2C interface modes, and the AD7992-1 supports standard, fast, and high speed I2C interface modes.
