Mouser stocks TI’s 12-bit SAR ADCs

Distributor, Mouser Electronics, is now stocking the ADS7028 and ADS7138 12-bit ADCs from Texas Instruments (TI). The eight-channel, multiplexed, successive approximation register (SAR) ADCs are designed for applications that demand reliable performance, says Mouser, such as rack servers, AC drive power stage modules, automotive centre information displays and CPU boards for mobile robots.

The ADS7028 and ADS7138 ADCs’ eight channels that can be configured in any combination of analogue inputs, digital inputs, or digital outputs. They feature an internal oscillator for ADC processes and a built-in cyclical redundancy check for power-up configuration and data read/write operations.

Both ADCs feature open-drain, push-pull digital outputs for I/O expansion and the analogue watchdog function includes an event counter for transient rejection and programmable thresholds for each channel. They also have wide operating ranges of 2.35V to 5.5V AVDD and 1.65V to 5.5V DVDD.

The ADS7028 communicates through an SPI-compatible interface with a sampling frequency of 1Msamples per second and the ADS7138 communicates using an I²C-compatible interface capable of operating at a frequency of up to 3.4MHz. Both ADCs operate in either autonomous or single-shot conversion mode.

The ADS7028 ADC also offers a root-mean-square module that computes a 16-bit true RMS output for any analogue input, as well as a zero-crossing-detect module that features built-in transient rejection and hysteresis near configurable threshold crossings.
