2-Channel, 12-Bit ADC with I2C Compatible Interface in 10-Lead MSOP
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.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The EVAL-AD7992EBZ is a fully featured evaluation Board for the AD7992. The evaluation board can be operated in complete standalone mode or connected to a PC via a standard USB interface. When operated with a PC, software is provided enabling the user to perform detailed analysis of the ADC's performance. This software includes the technical note describing the operation and set up of the evaluation board.
Please note: This Evaluation software does not run on Windows 8 or Windows 10 (USB driver is non-compliant with OS >Windows 7).
