LMH6733 SNOSAW0D – JANUARY 2007 – REVISED MAY 2013 www.ti.com High speed amplifiers are sensitive to capacitance between the inverting input and ground or power supplies. This shows up as gain peaking at high frequency. The capacitor raises device gain at high frequencies by making RG appear smaller. Capacitive output loading will exaggerate this effect. In general, avoid introducing unnecessary parasitic capacitance at both the inverting input and the output.

LMH6733 www.ti.com SNOSAW0D – JANUARY 2007 – REVISED MAY 2013 Power Dissipation The LMH6733 is optimized for maximum speed and performance in the small form factor of the standard SSOP16 package. To achieve its high level of performance, the LMH6733 consumes an appreciable amount of quiescent current which cannot be neglected when considering the total package power dissipation limit.
PAGE 18
LMH6733 SNOSAW0D – JANUARY 2007 – REVISED MAY 2013 www.ti.com ESD Protection The LMH6733 is protected against electrostatic discharge (ESD) on all pins. The LMH6733 will survive 2000V Human Body Model and 200V Machine Model events. Under closed loop operation the ESD diodes have no affect on circuit performance. There are occasions, however, when the ESD diodes will be evident. If the LMH6733 is driven by a large signal while the device is powered down the ESD diodes will conduct.
