Product Overview

The AD7991YRJZ-1500RL7 is a 4-channel low power successive approximation Analog-to-digital Converter (ADC) with an I²C®-compatible interface. The track-and-hold amplifier allows each part to handle input frequencies of up to 14MHz and a multiplexer allows taking samples from four channels. It provides a 2-wire serial interface compatible with I²C interfaces. The converter comes in 2 versions and each version has an individual I²C address. This allows two of the same devices to be connected to the same I²C bus. Both versions support standard fast and high speed I²C interface modes. The converter comes in one version. It normally remains in a shutdown state, powering up only for conversions. The conversion process is controlled by a command mode, during which each I²C read operation initiates a conversion and returns the result over the I²C bus. When 4 channels are used as analog inputs, the reference for the part is taken from VDD, this allows the widest dynamic input range to the ADC.
  • Sequencer operation
  • I²C-compatible serial interface supports standard, fast and high speed modes
  • Low power consumption
