2 / 20 page –2– REV. A AD8307–SPECIFICATIONS (V S = +5 V, TA = 25 C, RL ≥ 1M , unless otherwise noted) Parameter Conditions Min Typ Max Units GENERAL CHARACTERISTICS Input Range ( ±1 dB Error) Expressed in dBm re 50 Ω –72 16 dBm Logarithmic Conformance f ≤ 100 MHz, Central 80 dB ±0.3 ±1dB f = 500 MHz, Central 75 dB ±0.5 dB Logarithmic Slope Unadjusted 1 23 25 27 mV/dB vs. Temperature 23 27 mV/dB Logarithmic Intercept Sine Amplitude; Unadjusted 2 20 µV Equivalent Sine Power in 50 Ω –87 –84 –77 dBm vs. Temperature –88 –76 dBm Input Noise Spectral Density Inputs Shorted 1.5 nV/ √Hz Operating Noise Floor RSOURCE = 50 Ω/2 –78 dBm Output Resistance Pin 4 to Ground 10 12.5 15 k Ω Internal Load Capacitance 3.5 pF Response Time Small Signal, 10%-90%, 400 ns 0 mV–100 mV, CL = 2 pF Large Signal, 10%-90%, 500 ns 0 V–2.4 V, CL = 2 pF Upper Usable Frequency 3 500 MHz Lower Usable Frequency Input AC-Coupled 10 Hz AMPLIFIER CELL CHARACTERISTICS Cell Bandwidth –3 dB 900 MHz Cell Gain 14.3 dB INPUT CHARACTERISTICS DC Common-Mode Voltage Inputs AC-Coupled 3.2 V Common-Mode Range Either Input (Small Signal) –0.3 1.6 VS – 1 V DC Input Offset Voltage 4 RSOURCE ≤ 50 Ω 50 500 µV Drift 0.8 µV/°C Incremental Input Resistance Differential 1.1 k Ω Input Capacitance Either Pin to Ground 1.4 pF Bias Current Either Input 10 25 µA POWER INTERFACES Supply Voltage 2.7 5.5 V Supply Current VENB ≥ 2 V 8 10 mA Disabled VENB ≤ 1 V 150 750 µA NOTES 1This may be adjusted downward by adding a shunt resistor from the Output to Ground. A 50 k Ω resistor will reduce the nominal slope to 20 mV/dB. 2This may be adjusted in either direction by a voltage applied to Pin 5, with a scale factor of 8 dB/V. 3See Application on 900 MHz operation. 4Normally nulled automatically by internal offset correction loop. May be manually nulled by a voltage applied between Pin 3 and Ground; see APPLICATIONS. Specifications subject to change without notice. |
