LMH6502 June 2004 LMH6502 Wideband, Wideband, Low Power, Linear-in-dB Variable GainAmplifierGeneral Description Features The LMHTM6502 is a wideband DC coupled differential input V = ±5V, T = 25°C, R = 1k, R = 174, R = 100, A S A F G L V Low voltage controlled gain stage followed by a high-speed cur- = A = 10 Typical values unless specified. V(MAX) rent feedback Op Amp which can directly drive a low imped- n -3dB BW 130MHz ance load. Gain adjustment range is more than 70dB for up n Gain control BW 100MHz Power to 10MHz. n Adjustment range (typical over temp) 70dB Maximum gain is set by external components and the gain n Gain matching (limit) ±0.6dB can be reduced all the way to cut-off. Power consumption is n Slew rate 1800V/µs 300mW with a speed of 130MHz. Output referred DC offset n Supply current (no load) 27mA , voltage is less than 350mV over the entire gain control Linear-in-dB voltage range. Device-to-device Gain matching is within n Linear output current ±75mA ±0.6dB at maximum gain. Furthermore, gain at any V is n Output voltage (R = 100) ±3.2V L G tested and the tolerance is guaranteed. The output current n Input voltage noise 7.7nV/ feedback Op Amp allows high frequency large signals (Slew n Input current noise
