Product Description

The AD7689ACPZ is a 8-channel 16-bit 250kSPS PulSAR® Analogue to Digital Converter (ADC) that operates from a single power supply. It contains all components for use in a multichannel, low power data acquisition system, including a true 16-bit SAR ADC with no missing codes, a 8-channel low crosstalk multiplexer that is useful for configuring the inputs as single-ended (with or without ground sense), differential or bipolar, an internal low drift reference (selectable 2.5V or 4.096V) and buffer, a temperature sensor, a selectable one-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.
