AD7890AR-2 Frequently Asked Questions (FAQ)
-
The recommended power-up sequence is to apply VCC first, followed by VREF, and then the analog input signal. This ensures proper operation and prevents damage to the device.
-
The AD7890AR-2 outputs data in a 16-bit, two's complement format. The most significant bit (MSB) is the sign bit, and the remaining 15 bits represent the magnitude of the signal. The output data can be easily converted to a signed integer or floating-point format for further processing.
-
The VREF pin is used to set the reference voltage for the analog-to-digital conversion. The AD7890AR-2 can operate with an external reference voltage between 2.5 V and 5 V. The reference voltage determines the full-scale input range of the ADC.
-
To ensure accurate conversions, it is essential to provide a clean and stable power supply, a low-noise analog input signal, and a stable reference voltage. Additionally, the analog input signal should be within the specified input range, and the device should be operated within the recommended temperature range.
-
The AD7890AR-2 has a maximum throughput rate of 100 kSPS (kilo-samples per second). This means it can perform up to 100,000 conversions per second.
