ADS8028IRTJT (TEXAS INSTRUMENTS)

The ADS8028IRTJT is a 8-channel 12-bit Analog-to-digital Converter (ADC) capable of operating at sampling speeds up to 1MSPS. 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 8 analog input channels, the ADC 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 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 to 5.25V, enabling direct interface with a wide range of processors and controllers. The device offers flexible power-down modes to save power when conversions are not being performed. The ADC is ideal for demanding measurement applications.
