The AD7992BRMZ-0 is a 2-channel 12-bit low power successive approximation Analog-to-digital Converter (ADC) with an I2C-compatible interface. The part contains a multiplexer and track-and-hold amplifier that can handle input frequencies up to 11MHz. It normally remains in a shutdown state while not converting and powers up only for conversions. The conversion process can be controlled using the CONVST pin by a command mode where conversions occur across I2C write operations or an automatic conversion interval mode selected through software control. It requires an external reference in the range of 1.2 to VDD. This allows the widest dynamic input range to the ADC. On-chip limit registers can be programmed with high and low limits for the conversion result and an open-drain out-of-range indicator output becomes active when the conversion result violates the programmed high or low limits.

• Output can be used as an interrupt
• Low power consumption
• Sequencer operation
• Automatic cycle mode
• Out-of-range indicator/alert function
• Pin-selectable addressing via AS
