General Description The LM6362 family of high-speed amplifiers exhibits an excellent speed-power product, delivering 300 V/µs and 100 MHz gain-bandwidth product (stable for gains as low as +2 or −1) with only 5 mA of supply current. Further power savings and application convenience are possible by taking advantage of the wide dynamic range in operating supply voltage which extends all the way down to +5V. These amplifiers are built with National’s VIP™ (Vertically Integrated PNP) process which provides fast transistors that are true complements to the already fast NPN devices. This advanced junction-isolated process delivers high speed performance without the need for complex and expensive dielectric isolation.

Electrical specifications do not apply when operating the device beyond its rated operating conditions. Note 2: The ESD protection circuitry between the inputs will begin to conduct when the differential input voltage reaches 8V. Note 3: a) In addition, the voltage between the V+ pin and either input pin must not exceed 36V. 3V below the negative supply pin voltage, a substrate diode begins to conduct. Current through this pin must then be kept less than 20 mA to limit damage from self-heating. Note 4: Although the output current is internally limited, continuous short-circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150˚C. Note 5: This value is the average voltage that the weakest pin combinations can withstand and still conform to the datasheet limits. The test circuit used consists of the human body model, 100 pF in series with 1500Ω. Note 6: The typical thermal resistance, junction-to-ambient, of the molded plastic DIP (N package) is 105˚C/W. For the molded plastic SO (M package), use 155˚C/W. All numbers apply for packages soldered directly into a printed circuit board. Note 7: Typical values are for TJ = 25˚C, and represent the most likely parametric norm.

Note 10: For single-supply operation, the following conditions apply: V+ = 5V, V− = 0V, VCM = 2.5V, VOUT = 2.5V. Pin 1 and Pin 8 (VOS Adjust pins) are each connected to pin 4 (V−) to realize maximum output swing. This connection will increase the offset voltage. Note 11: VIN = 10V step. For ± 5V supplies, VIN = 1V step. Note 12: A military RETS electrical test specification is available on request.

No. 1 cmserv Proof 6 Simplified Schematic DS011061-1 Application Tips Power supply bypassing is not as critical for LM6362 as it is for other op amps in its speed class. However, bypassing will improve the stability and transient response of the LM6362, and is recommended for every design. 0.01 µF to 0.1 µF ceramic capacitors should be used (from each supply “rail” to ground); if the device is far away from its power supply source, an additional 2.2 µF to 10 µF of tantalum may be required for extra noise reduction. Keep all leads short to reduce stray capacitance and lead inductance, and make sure ground paths are low-impedance, especially where heavier currents will be flowing. Stray capacitance in the circuit layout can cause signal coupling from one pin, input or lead to another, and can cause circuit gain to unintentionally vary with frequency. Breadboarded circuits will work best if they are built using generic PC boards with a good ground plane. If the op amps are used with sockets, as opposed to being soldered into the circuit, the additional input capacitance may degrade circuit frequency response. At low gains (+2 or −1), a feedback capacitor Cf from output to inverting input will compensate for the phase lag caused by capacitance at the inverting input. Typically, values from 2 pF to 5 pF work well; however, best results can be obtained by observing the amplifier pulse response and optimizing Cf for the particular layout. The LM6362 has been decompensated for a wider gain-bandwidth product than the LM6361. However, the LM6362 still offers stability at gains of 2 (and −1) or greater over the specified ranges of temperature, power supply voltage, and load. Since this decompensation involved reducing the emitter-degeneration resistors in the op amp’s input stage, the DC precision has been increased in the form of lower offset voltage and higher open-loop gain. Other op amps in this family include the LM6361, LM6364, and LM6365. If unity-gain stability is required, the LM6361 should be used. The LM6364 has been decompensated for operation at gains of 5 or more, with corresponding greater gain-bandwidth product (125 MHz, typical) and DC precision. The fully-uncompensated LM6365 offers gain-bandwidth product of 725 MHz, typical, and is stable for gains of 25 or more. All parts in this family, regardless of compensation, have the same high slew rate of 300 V/µs (typ). The LM6362 is unusually tolerant of capacitive loads. Most op amps tend to oscillate when their load capacitance is greater than about 200 pF (in low-gain circuits). However, load capacitance on the LM6362 effectively increases its compensation capacitance, thus slowing the op amp’s response and reducing its bandwidth. The compensation is not ideal, though, and ringing may occur in low-gain circuits with large capacitive loads. 7 PrintDate=1997/09/29 PrintTime=12:36:23 18016 ds011061 Rev.
