Choosing the feedback circuit

As described in Figure 67 on page 29, the TS616 requires a 620

Ω feedback resistor to

optimize the bandwidth with a gain of 12 dB for a 12 V power supply. Nevertheless, due to

production test constraints, the TS616 is tested with the same feedback resistor for 12 V and

5 V power supplies (910

Ω).
