Output voltage range • Output Short Circuit Current +115 mA to 145 mA extends to within 40 mV of either supply rail, allowing • Linear Output Current ±75 mA wide dynamic range especially desirable in low • Input Common Mode Volt. 0.5 V Beyond V−, 1 V voltage applications. The output stage is capable of from V+ approximately 75 mA in order to drive heavy loads. Fast output Slew Rate (130 V/µs) ensures large • Output Voltage Swing 40 mV from Rails peak-to-peak output swings can be maintained even • Input Voltage Noise (100 kHz) 17nV/ √Hz at higher speeds, resulting in exceptional full power • Input Current Noise (100 kHz) 0.9pA/ √Hz bandwidth of 40 MHz with a 3 V supply. These characteristics, along with low cost, are ideal features • THD (5MHz, RL = 2kΩ, VO = 2VPP, AV = +2) −62 for a multitude of industrial and commercial dBc applications. • Settling Time 68 ns • Fully Characterized for 3 V, 5 V, and ±5 V Device Information(1) • Overdrive Recovery 100 ns PART NUMBER PACKAGE BODY SIZE (NOM) • Output Short Circuit Protected(2) SOT-23 (5) 2.90 mm × 1.60 mm LMH6642 SOIC (8) 4.90 mm × 3.91 mm • No Output Phase Reversal with CMVR Exceeded SOIC (8) LMH6643 3.00 mm × 3.00 mm (1) Slew rate is the average of the rising and falling slew rates VSSOP (8) (2) Output short circuit duration is infinite for V S < 6 V at room SOIC (14) 8.64 mm × 3.91 mm temperature and below. For VS > 6 V, allowable short circuit LMH6644 TSSOP (14) 5.00 mm × 4.40 mm duration is 1.5 ms.
