The AD7992 is a 12-bit, high speed, low power, successive- approximation ADC. The part operates from a single 2.7 V to 5.5 V power supply and features a conversion time of 2 µs. The part contains a two channel multiplexer and track/hold amplifier.
The AD7992 provides a two-wire serial interface which is compatible with I2C interfaces. The part comes in two versions, AD7992-0, and AD7992-1. Each version allows for a minimum of two different I2C addresses. The AD7992-0 supports Standard and Fast I2C interface Modes, while the AD7992-1 supports Standard, Fast, and two High-Speed I2C Interface Modes.
