Texas Instruments provides a layout and routing guide in the application note SLAA523, which includes recommendations for PCB layout, component placement, and routing to minimize noise and ensure optimal performance.
The ADS7871IDBRG4 does not require calibration in the classical sense. However, it's recommended to perform a system-level calibration to account for gain and offset errors. This can be done by applying a known input voltage and measuring the output code, then adjusting the system's gain and offset accordingly.
The ADS7871IDBRG4 has a maximum input voltage range of 5.5V, which is the same as the supply voltage. However, the recommended input voltage range is 0V to 5V to ensure accurate conversions.
Yes, the ADS7871IDBRG4 can be used in a multiplexed configuration. However, it's essential to ensure that the multiplexer is designed to minimize signal degradation and noise injection. Texas Instruments provides guidance on multiplexing in the application note SLAA525.
The ADS7871IDBRG4 has a built-in POR circuit that ensures the device powers up in a known state. When the supply voltage rises above 1.5V, the POR circuit resets the device, and it takes approximately 10ms for the device to become operational.
