SBAS979B June 2019 – June 2020 ADS7038
PRODUCTION DATA.
The ADS7038 is a small, eight-channel, multiplexed, 12-bit, 1-MSPS, analog-to-digital converter (ADC) with an enhanced-SPI serial interface. The eight channels of the ADS7038 can be individually configured as either analog inputs, digital inputs, or digital outputs. The device includes a digital comparator which can be used to interrupt the host when a programmed high or low threshold is crossed on any input channel. The device uses an internal oscillator for conversion. The ADC can be used in manual mode for reading ADC data over the SPI interface or in autonomous mode for monitoring the analog inputs without an active SPI interface.
The device features a programmable averaging filter that outputs a 16-bit result for enhanced resolution.
