Summary
The Texas Instruments ADC128S102-SEP is a radiation-tolerant analog-to-digital converter (ADC) designed for space applications. It is a low-power, eight-channel, CMOS, 12-bit ADC specified for conversion throughput rates of 50 kSPS to 1 MSPS.
The converter is based on a successive approximation register (SAR) architecture with an internal track-and-hold circuit. It can be configured to accept up to eight input signals at inputs IN0 through IN7.
Its output serial data is straight binary and compatible with several standards, such as SPI, QSPI, MICROWIRE, and many common DSP serial interfaces. The ADC128S102-SEP can be operated with independent analog and digital supplies.
