Based on easy • −3dB BW (AV = +1) 270MHz to use voltage feedback topology and boasting fast • Supply Voltage Range 3V to 12V slew rate (700V/µs) and high speed (140MHz GBWP), the LMH6657 (Single) and LMH6658 (dual) • Slew Rate, (VS = ±5V) 700V/µs can be used in high speed large signal applications. • Supply Current 6.2mA/amp These applications include instrumentation, • Output Current +80/ −90mA communication devices, set-top boxes, etc. • Input Common Mode volt. 0.5V Beyond V−, With a -3dB BW of 100MHz (AV = +2) and DG & DP 1.7V from V+ of 0.03% & 0.10° respectively, the LMH6657/6658 are well suited for video applications. The output • Output Voltage Swing (RL = 2kΩ) 0.8V from stage can typically supply 80mA into the load with a Rails swing of about 1V from either rail. • Input Voltage Noise 11nV/ √Hz For Industrial applications, the LMH6657/6658 are • Input Current Noise 2.1pA √Hz/ excellent cost-saving choices. Input referred voltage • DG Error 0.03% noise is low and the input voltage can extend below • DP Error 0.10° V− to ease amplification of low level signals that could be at or near the system ground. With low distortion • THD (5MHz) −55dBc and fast settling, LMH6657/6658 can provide • Settling Time (0.1%) 37ns buffering for A/D and D/A applications. • Fully Characterized for 5V, and ±5V The LMH6657/6658 versatility and ease of use is • Output Overdrive Recovery 18ns extended even further by offering these high slew • Output Short Circuit Protected(1) rate , high speed Op Amps in miniature packages such as SOT-23-5, SC70, SOIC-8, and VSSOP-8. • No Output Phase Reversal with CMVR Refer to the Ordering Information section for Exceeded packaging options available for each device. APPLICATIONS • CD/DVD ROM • ADC Buffer Amp • Portable Video • Current Sense Buffer • Portable Communications (1) Short Circuit Test is a momentary test.
