Easy to use 12-bit analog-to-digital converters

30-01-2020 | Texas Instruments | Semiconductors

Texas Instruments ADS7038 12-Bit ADCs are an easy-to-use, eight-channel, multiplexed, 12-bit, 1MSPS, SAR ADC. The eight channels can be individually configured as either analog inputs, digital inputs, or digital outputs. The device possesses an internal oscillator for the ADC conversion process.


The ADC communicates through an SPI-compatible interface and functions in either autonomous or single-shot conversion mode. The device executes the analog watchdog function by event-triggered interrupts per channel employing a digital window comparator with programmable high and low thresholds, hysteresis, and an event counter. The device has a built-in CRC for data read/write operations and the power-up configuration.


Typical applications include macro remote radio units, battery management systems, string inverters, and central inverters.
