Electrical Characteristics: General (Continued)

All parameters refer to GND and are valid for Tamb = -40°C to +105°C, VVS1 = VVS2 = 2.4 V to 3.6 V (1-battery application),

VVS2 = 4.4 V to 6.6 V (2-battery application) and VVS2 = VVAUX = 4.75 V to 5.25 V (car application). Typical values are given

at VVS1 = VVS2 = 3 V and Tamb = 25°C, fRF = 433.92 MHz (1-battery application) unless otherwise specified. Details about cur-

rent consumption, timing and digital pin properties can be found in the specific sections of the “Electrical Characteristics”.

Note:

1. Pin numbers in brackets mean they were measured with RF_IN matched to 50

Ω according to Figure 7 on page 10 with

component values according to Table 2 on page 10 and RF_OUT matched to 50

Ω according to Figure 16 on page 19 with

component values according to Table 7 on page 19.
