The ADS8028 is a 12-bit analog-to-digital converter (ADC), capable of operating at sampling speeds up to 1 MSPS. The device is based on a successive approximation register (SAR) core and provides an inherent sample-and-hold (SH) front-end.
In addition to having eight analog input channels, the ADS8028 offers an internal temperature sensor with 0.25°C resolution and an internal voltage reference. A nine-channel internal multiplexer enables multiple channels to be selected (including the internal temperature sensor) that are indefinitely scanned in a sequential manner. A simple SPI-compatible serial interface provides easy communication and control between the device and host controller. The digital supply can operate from 1.65 V to 5.25 V, enabling direct interface with a wide range of processors and controllers.
At full speed of 1 MSPS, the ADS8028 dissipates only 17 mW. The device offers flexible power-down modes to save power when conversions are not being performed. The ADS8028 performance is specified over the extended industrial temperature range of –40°C to +125°C.
The ADS8028 is ideal for demanding measurement applications, such as sensor output monitoring, power-supply monitoring, and printed circuit board (PCB) hot-spot analysis, and is available in a small form-factor QFN-20 package.
