The ADS1234IPWR requires careful layout and placement to ensure optimal performance. TI recommends placing the device close to the analog signal source, using a solid ground plane, and keeping the analog and digital traces separate. Additionally, the device should be placed on a multi-layer PCB with a dedicated analog ground plane.
The ADS1234IPWR requires calibration for optimal performance. TI recommends using the internal calibration feature, which can be enabled through the CAL_EN pin. Additionally, the gain and offset can be adjusted through the PGA_GAIN and OFFSET_ADJ pins. It's also recommended to use an external calibration circuit to fine-tune the gain and offset.
The ADS1234IPWR requires a specific power-up sequence to ensure proper operation. TI recommends powering up the device in the following order: AVDD, DVDD, and then the analog input signal. This sequence helps to prevent latch-up and ensures that the device is properly initialized.
The ADS1234IPWR outputs 24-bit digital data in a serial format. TI recommends using a microcontroller or FPGA to receive and process the data. The data can be clocked out of the device using the SCLK pin, and the data format can be configured through the MODE pin.
The ADS1234IPWR requires a filtered analog input signal to ensure optimal performance. TI recommends using a low-pass filter with a cutoff frequency of around 100 kHz to remove high-frequency noise and aliasing. A simple RC filter or a more complex active filter can be used, depending on the specific application requirements.
