† All typical values are at VCC = 5 V, VBB = –5 V, and TA = 25°C.
‡ Absolute rms signal levels are defined as follows: VI = 1.2276 V = 0 dBm0 = 4 dBm at f = 1.02 kHz with RL = 600 Ω.
NOTE 4: Full range for the TP3054B and TP3057B is 0
°C to 70°C. Full range for the TP13054B and TP13057B is –40°C to 85°C.
