Product Description

The AD7949BCPZ is a 8-channel charge redistribution successive approximation register Analog-to-digital Converter (ADC) that operates from a single power supply VDD. It contains all components for use in a multi-channel low power data acquisition system including a true 14-bit SAR ADC with no missing codes, a 8-channel low crosstalk multiplexer that is useful for configuring the inputs as 1-ended differential or bipolar, an internal low drift reference and buffer, a temperature sensor, a selectable 1-pole filter and a sequencer that is useful when channels are continuously scanned in order. It uses a simple SPI interface for writing to the configuration register and receiving conversion results. The SPI interface uses a separate supply VIO which is set to the host logic level.
Power dissipation scales with throughput
Multiple reference types
Internal temperature sensor (TEMP)
