Part Details:

LMH6642/LMH6643/LMH6644 October 2006 LMH6642/LMH6643/LMH6644Low Power, 130MHz, 75mA Rail-to-Rail Output AmplifiersGeneral Description in single (LMH6642), dual (LMH6643), and quad (LMH6644)options. See ordering information for packages offered. The LMH664X family true single supply voltage feedbackamplifiers offer high speed (130MHz), low distortion Features (-62dBc), and exceptionally high output current (approxi-mately 75mA) at low cost and with reduced power consump- (V = ±5V, T = 25°C, R = 2k, A = +1.

Output voltage range extends to within n Slew rate (Note 8), (A = -1) 130V/µs V 40mV of either supply rail, allowing wide dynamic range Low n Supply current (no load) 2.7mA/amp especially desirable in low voltage applications. The output n Output short circuit current +115mA/-145mA stage is capable of approximately 75mA in order to drive n Linear output current ±75mA heavy loads. Fast output Slew Rate (130V/µs) ensures large Power n Input common mode volt. 0.5V beyond V-, 1V from V+ peak-to-peak output swings can be maintained even athigher speeds, resulting in exceptional full power bandwidth n Output voltage swing 40mV from rails of 40MHz with a 3V supply. These characteristics, along with n Input voltage noise (100kHz) 17nV/ low cost, are ideal features for a multitude of industrial and n Input current noise (100kHz) 0.9pA/ , commercial applications. n THD (5MHz, R
