A 4-layer PCB with a solid ground plane, separate analog and digital power planes, and a star-connected decoupling capacitor network is recommended. Additionally, keep analog and digital traces separate and avoid crossing them.
The internal voltage reference can be configured by setting the VREF_SEL pin to select the desired reference voltage. Ensure the reference voltage is stable and within the recommended range (1.2V to 3.3V) for optimal accuracy.
The recommended clock frequency is 10 MHz to 50 MHz. A higher clock frequency can improve conversion speed, but may also increase power consumption and noise sensitivity. A lower clock frequency can reduce power consumption, but may also reduce conversion speed.
The AMC7823IRTAR's digital output data is 16-bit, right-justified, and binary-coded. A recommended approach is to use a FIFO or a buffer to handle the data, and then process it using a microcontroller or DSP. Apply digital filtering and averaging to reduce noise and improve accuracy.
The AMC7823IRTAR has a maximum junction temperature of 150°C. Ensure good thermal conductivity between the device and the PCB, use thermal vias, and consider heat sinks or thermal interfaces to dissipate heat. Avoid thermal gradients and hot spots.
