Analog Devices have recently introduced two 12-bit, 8-channel ADC/DAC/GPIO combination chips which are user-configurable in any functional combination. The AD5592R (SPI Interface) and AD5593R (I²C Interface) ADC/DAC/GPIO combination devices include a 400-Ksps ADC (analog-to-digital converter), 6¼ sec settling time DAC (digital-to-analog converter), digital inputs/outputs, and a reference on a single chip.
The AD5592R and AD5593R devices can be user-configured in any combination of up to eight variations, allowing designers to use a single chip to complete multiple system monitoring and control functions. The combination of on-chip features allows system designers to reduce bill of materials costs and increase design portability and reuse with only minor software changes.
The feature packed single-chip solution can save up to 85% of the space required by discrete implementations. The level of integration and small package sizes make the devices suitable for high-density and space-constrained applications such as wired and wireless communications, building control or any general monitoring or control application where size and design flexibility are key requirements. The new devices not only simplify system architectures but enable greater system functionality because of the ability to add extra control and monitoring capabilities within a single device.
