8.2.1.2.1 Configuration Example

In a 3.3-V system, 3.2 V ≤ Vref ≤ 3.4 V. Use Equation 3 to calculate the allowable range for R1.

Equation 3. GUID-3FB5AF64-D19A-474D-B307-4ECB0CF03C01-low.gif

For this design example, use Equation 4 to calculate the allowable range of R1.

Equation 4. GUID-00FF996D-BD72-49EA-8DAE-8F9DEEC84E66-low.gif

Therefore:

Equation 5. 113 Ω ≤ R1 ≤ 32 kΩ

After finding the allowable range of R1 (Equation 5), select a value between 500 Ω and 32 kΩ for R1.

Assuming a system bandwidth of 10 kHz, use Equation 6 to calculate the value of C2.

Equation 6. GUID-979C48D1-3A70-4B13-A944-9444D02F125D-low.gif

For this design example, use Equation 7 to calculate the value of C2.

Equation 7. GUID-93974905-5230-4C83-A5F7-FA9DAB444E11-low.gif

An R1 value of 10 kΩ and a C2 value less than 820 pF satisfy the requirement for a 10-kHz system bandwidth.

A selection of R1 = 10 kΩ and C2 = 680 pF would cause a low-pass filter with a corner frequency of 23.4 kHz.
