Single-ended input configuration
The TS4601B can be used in single-ended input configuration. InR- and InL- must be
shorted to ground through input capacitors. All Cin capacitors must have the same value to
keep the same PSRR performance as in differential input configuration. Figure 52 shows an
example.
