Texas Instruments provides a recommended PCB layout in the ADS4128IRGZ25 evaluation module documentation, which includes guidelines for component placement, routing, and grounding to minimize noise and ensure optimal performance.
The ADS4128IRGZ25 requires a two-point calibration process, which involves applying a known input voltage and adjusting the offset and gain registers to achieve accurate measurements. The calibration process is described in the device's datasheet and application notes.
The ADS4128IRGZ25 has a maximum input voltage range of ±VREF (±2.5V typical), but it's recommended to limit the input voltage to ±1.5V to ensure optimal linearity and accuracy.
The ADS4128IRGZ25 has internal overvoltage protection up to ±6V, but it's recommended to add external protection circuitry, such as clamping diodes or voltage-limiting resistors, to prevent damage from higher voltage transients.
The ADS4128IRGZ25 can operate with clock frequencies up to 80 MHz, but the recommended frequency is 40 MHz to ensure optimal performance and minimize power consumption.
