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 unacceptably drain 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.

If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications. ESD Tolerance (Note 2) 2500V Differential Input Voltage 15V Voltage at Input/Output Pin (V+) + 0.3V, (V−) −0.3V Supply Voltage (V+ − V−) 35V Current at Input Pin ±10mA Current at Output Pin(Note 3) ±25mA Current at Power Supply Pin 50mA Lead Temperature(soldering, 10 sec) 260°C Storage Temperature Range -65°C to +150°C Junction Temperature (Note 4) 150°C Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics. Note 2: Human body model, 1.5kW in series with 100pF. Note 3: Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150°C. Note 4: The maximum power dissipation is a function of TJ(max) , JA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max)-T A)/JA. All numbers apply for packages soldered directly into a PC board.
