Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (VDD) is within the range of 4.5V to 5.5V.
   • Connect the ground (GND) pin to the system ground.

2. Shutdown Mode:

   • To enter shutdown mode, set the SHDN pin to a high state.
   • The shutdown current is typically 1 μA at 25°C.

3. Active Mode:

   • To activate the device, set the SHDN pin to a low state.
   • The active current consumption is typically 1.5 mA at 25°C with a 1 MHz SCLK frequency.

4. Clocking:

   • Apply a serial clock (SCLK) signal to the device. The maximum output data rate (fODR) is 200 kSPS.
   • Ensure the SCLK frequency is within the specified range for proper operation.

5. Data Output:

   • The device outputs 12-bit data. The data is available on the SDATA pin.
   • The data is read out in MSB-first format.

6. Input Signal:

   • The input voltage range (VIN) should be between 0V and VDD.
   • Ensure the input signal is within this range to avoid damage or incorrect readings.

7. Calibration:

   • Perform calibration if required to ensure accurate readings.
   • Refer to the device datasheet for specific calibration procedures.

8. Environmental Conditions:

   • Operate the device within the temperature range of -40°C to 85°C to ensure reliable performance.

9. Signal Quality:

   • The device has a typical signal-to-noise ratio (SNR) of 72 dB and a total harmonic distortion (THD) of -80 dB at 1 kHz input.

10. Nonlinearity:

    • The differential nonlinearity (DNL) is ±1 LSB and the integral nonlinearity (INL) is ±2 LSB over the full scale range at 25°C.
