LM6152/LM6154Dual and Quad High Speed/Low Power 75 MHz GBW Rail-to-Rail I/O Operational
Amplifiers
General Description
Using patented circuit topologies, the LM6152/54 provides new levels of speed vs. power performance in applications where low voltage supplies or power limitations previously made compromise necessary. With only 1.4 mA/amplifier supply current, the 75 MHz gain bandwidth of this device supports new portable applications where higher power de­vices unacceptablydrain battery life. The slew rate of the de­vices increases with increasing input differential voltage, thus allowing the device to handle capacitive loads while maintaining large signal amplitude.
The LM6152/54 can be driven by voltages that exceed both power supply rails, thus eliminating concerns about exceed­ing the common-mode voltage range. The rail-to-rail output swing capability provides the maximum possible dynamic range at the output. This is particularly important when oper­ating on low supply voltages.
Operating on supplies from 2.7V to over 24V, the LM6152/54 is excellent for a very wide range of applications, from bat­tery operated systems with large bandwidth requirements to high speed instrumentation.

Application Information
The LM6152/6154 is ideally suited for operation with about 10k(Feedback Resistor, R negative input terminal.
With R

F
Because of the unique structure of this amplifier, when used at low closed loop gains, the realizable BW will be much less than the GBW product would suggest.
The LM6152/6154 brings a new level of ease of use to op amp system design.
The high gain-bandwidth with low supply current opens new battery powered applications where higher power consump­tion previously reduced battery life to unacceptable levels.
The ability to drive large capacitive loads without oscillating functional removes this common problem.
To take advantage of these features, some ideas should be kept in mind.
The LM6152/6154, capacitive loads do not lead to oscilla­tions, in all but the most extreme conditions, but they will re­sult in reduced bandwidth. They also cause increased set­tling time.
Unlike most bipolar op amps, the unique phase reversal prevention/speed-up circuit in the input stage, caused the slew rate to be very much a functionof the input pulse ampli­tude. This results in a 10 to 1 increase in slew rate when the
F
differential input signal increases. Large fast pulses will raise the slew-rate to more than 30V/µs.

The speed-up action adds stability to the system when driv­ing large capacitive loads.
A conventional op amp exhibits a fixed maximum slew-rate even though the differential input voltage rises due to the lagging output voltage. In the LM6152/6154, increasing lag causes the differential input voltage to increase but as it does, the increased slew-rate keeps the output following the input much better. This effectively reduces phase lag. As a result, the LM6152/6154 can drive capacitive loads as large as 470 pF at gain of 2 and above, and not oscillate.
Capacitive loads decrease the phase margin of all op amps. This can lead to overshoot, ringing and oscillation. This is caused by the output resistance of the amplifier and the load capacitance forming an R-C phase shift network. The LM6152/6154 senses this phase shift and partly compen­sates for this effect.
