ATA5811/ATA5812 [Preliminary]
Electrical Characteristics: General (Continued)
All parameters refer to GND and are valid for T_amb = -40°C to +105°C, V_VS1 = V_VS2 = 2.4 V to 3.6 V (1-battery application),
V_VS2 = 4.4 V to 6.6 V (2-battery application) and V_VS2 = V_VAUX = 4.75 V to 5.25 V (car application). Typical values are given
at V_VS1 = V_VS2 = 3 V and T_amb = 25°C, f_RF = 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.
Electrical Characteristic: 1-Battery Application
All parameters refer to GND and are valid for T_amb = -40°C to +105°C, V_VS1 = V_VS2 = 2.4 V to 3.6 V typical values at
V_VS1 = V_VS2 = 3 V and T_amb = 25°C. Application according to Figure 4 on page 6. f_RF = 315.0 MHz/433.92 MHz/868.3 MHz
