TDA5252G2 INFINEON [Infineon Technologies AG], TDA5252G2 Datasheet - Page 62

• Manufacturer Part Number: TDA5252G2
• Description: ASK/FSK 915MHz Wireless Transceiver
• Manufacturer: INFINEON [Infineon Technologies AG]

3.6.2
Table 3-13
The TDA5252 has two peak detectors built in, one for positive peaks in the data stream and the
other for the negative ones.
Necessary external components:
Figure 3-23
For applications requiring fast attack and slow release from the threshold value it is reasonable to
use the peak detectors. The threshold value is generated by an internal voltage divider. The release
time is defined by the internal resistance values and the external capacitors.
