4 / 26 page Si4840/44-A10 4 Rev.1.0 1. Electrical Specifications Table 1. Recommended Operating Conditions1,2 Parameter Symbol Test Condition Min Typ Max Unit Supply Voltage3 VDD 2— 3.6 V Power Supply Powerup Rise Time VDDRISE 10 — — µs Notes: 1. Typical values in the data sheet apply at VDD = 3.3 V and 25 °C unless otherwise stated. 2. All minimum and maximum specifications in the data sheet apply across the recommended operating conditions for minimum VDD =2.7 V. 3. Operation at minimum VDD is guaranteed by characterization when VDD voltage is ramped down to 2.0 V. Part initialization may become unresponsive below 2.3 V. Table 2. DC Characteristics (VDD = 2.7 to 3.6 V, TA = –15 to 85 °C) Parameter Symbol Test Condition Min Typ Max Unit FM Mode Supply Current1 IFM —21.0— mA Supply Current2 IFM Low SNR level — 21.5 — mA AM/SW Mode Supply Current1 IAM —17.0— mA Supplies and Interface VDD Powerdown Current IDDPD —10— µA Notes: 1. Specifications are guaranteed by characterization. 2. LNA is automatically switched to higher current mode for optimum sensitivity in weak signal conditions. |
