Instructions for Use
Power Supply:
- Ensure the supply voltage (VDD) is within the range of 4.75V to 5.25V.
- The typical supply current (IDD) is 30mA.
Temperature Considerations:
- The operating temperature (Toper) should be between -40°C and +85°C.
- The storage temperature (Tstg) should be between -65°C and +150°C.
Input Signal:
- The input frequency range (fin) should be between 0kHz and 200kHz.
- The sine/cosine input range (Vin) should be between 0.5Vpp and 1.5Vpp.
Resolution and Conversion Time:
- The resolution can be set between 10 bits and 16 bits.
- For 16-bit resolution, the typical conversion time (tconv) is 31.25μs.
Linearity:
- The differential nonlinearity (DNL) for 16-bit resolution is ±1LSB.
- The integral nonlinearity (INL) for 16-bit resolution is ±5LSB.
Phase Error:
- The phase error (θerr) for 16-bit resolution is ±0.01°.
Output Data Rate:
- The output data rate (fODR) can be set between 0kSPS and 200kSPS.
General Usage:
- Connect the sine and cosine inputs to the appropriate pins.
- Configure the resolution and output data rate as needed.
- Ensure proper grounding and decoupling capacitors to minimize noise and improve performance.
