7.2.2.2 Differential to Single-Ended Output Conversion

For systems using single-ended input ADCs to convert the analog output voltage into digital, Figure 7-3 shows an example of a TLV313-Q1-based signal conversion and filter circuit. With R1 = R2 = R3 = R4, the output voltage equals (VOUTP – VOUTN) + VREF. Tailor the bandwidth of this filter stage to the bandwidth requirement of the system and use NP0-type capacitors for best performance. For most applications, R1 = R2 = R3 = R4 = 10 kΩ and C1 = C2 = 1000 pF yields good performance.
