Application information
Doc ID 17913 Rev 1
23/31
To switch the TS4604 back to standby, the voltage across the divider R1, R2 has to be lower
than 1.25 V - VHyst
× R1/(R1 + R2). The ESV can be an external voltage or simply the
power supply voltage PVcc_LD/HD.

2nd order Butterworth low-pass filter
The TS4604 can also be configured as a low-pass filter to be driven directly by a DAC
output. It can be used, for example, as a 2nd order low-pass filter, with either a differential
input or a single-ended input.
feedback 2nd order low-pass filter.
An AC-coupling capacitor should be added to block any DC component from the source,
which helps to reduce the output DC offset to a minimum.
Example 2nd-order multi-feedback filter in differential mode
Figure 53 shows a filter in differential mode with a cut-off frequency at 30 kHz (configured as
per the values in Table 8, which proposes various filter options using a differential input).
