6 / 39 page  LMH6553 SNOSB07H – SEPTEMBER 2008 – REVISED MARCH 2013 www.ti.com VS = ±2.5V Electrical Characteristics (1) (continued) Unless otherwise specified, all limits are ensured for TA = 25°C, VS = ±2.5V, AV = 1, VCM = 0V, VCLAMP = 2V, RF = RG = 275Ω, RL = 200Ω, for single-ended in, differential out. Boldface limits apply at the temperature extremes. Symbol Parameter Conditions Min (2) Typ (3) Max (2) Units HD3 3rd Harmonic Distortion VOUT = 2 VPP, f = 20 MHz, RL = 800Ω −78 dBc VOUT = 2 VPP, f = 70 MHz, RL = 800Ω −66 IMD3 3rd-Order Two-Tone fc = 20 MHz, VOUT = 2 VPP Composite, −87 Intermodulation RL = 200Ω dBc fc = 150 MHz, VOUT = 2 VPP Composite, −68 RL = 200Ω Input Noise Voltage f = 100 kHz 1.1 nV/ √Hz Input Noise Current f = 100 kHz 13.6 pA/ √Hz Noise Figure (See Figure 58) 50 Ω System, AV = 9, 10 MHz 10.3 dB Input Characteristics IBI Input Bias Current (4)(5) (5) −90 45 90 µA IBoffset Input Bias Current Differential (3) VCM = 0V, VID = 0V, IBoffset = (IB− - IB+)/2 −24 2 24 µA CMRR Common Mode Rejection Ratio (3) DC, VCM = 0V, VID = 0V 80 dBc RIN Input Resistance Differential 15 Ω CIN Input Capacitance Differential 0.5 pF CMVR Input Common Mode Voltage CMRR > 38 dB ±1.0 ±1.2 V Range Output Performance Output Voltage Swing (3) Differential Output 5.32 5.47 VPP IOUT Linear Output Current (3) VOUT = 0V ±75 ±95 mA ISC Short Circuit Current One Output Shorted to Ground VIN = 2V ±140 mA Single-Ended (6) Clamp Performance V CLAMP VCLAMP Voltage Range Continuous Operation (7) VCM VCM + V 2.0 VCLAMP Peak Voltage (8) VCM + 3.0 Default VCLAMP Voltage VCLAMP Floating 0.42 0.48 0.54 V Upper Clamp Level Accuracy VIN = 0V, VCLAMP = +0.5V, VCM = 0, VO = −39 −30 +39 +0.5V, 100% Overdrive mV Lower Clamp Level Accuracy VIN = 0V, VCLAMP = +0.5V, VCM = 0, VO = −18 6 +18 −0.5V, 100% Overdrive Clamp Accuracy Temperature Drift −0.1 mV/°C Clamp Pin Bias Current VIN = 0V, VCLAMP = 1V, VCM = 0 23.5 µA Clamp Pin Bias Drift 0.3 µA/°C Diff Amp Input Bias Shift Linear to Clamped Operation 50 µA Clamp Pin Input Impedance 30 k Ω/pF 1 Clamp Pin Feedthrough f = 10 MHz −60 dB Clamp Bandwidth 0.5VDC + 40 mVPP, SE VIN = 2V 125 MHz Clamp Slew Rate 100% Overdrive 52 V/µs (4) Exceeding limits could result in excessive device current. (5) IBI is referred to a differential output offset voltage by the following relationship: VOD(offset) = IBI*2RF (6) Short circuit current should be limited in duration to no more than 10 seconds. See POWER DISSIPATION in Application Information for more details. (7) Exceeding limits could result in excessive device current. (8) This parameter is ensured by design and/or characterization and is not tested in production. The condition of VCLAMP = 3V is not intended for continuous operation; continuous operation with VCLAMP = 3V may incur permanent damage to the device. 6 Submit Documentation Feedback Copyright © 2008–2013, Texas Instruments Incorporated Product Folder Links: LMH6553 |
