APPLICATION HINTS ON SUPPLY DECOUPLING

The use of supply decoupling is mandatory in most applications. As with most relatively high speed/high output

current op amps, best results are achieved when each supply line is decoupled with two capacitors; a small

value ceramic capacitor (∼0.01 µF) placed very close to the supply lead in addition to a large value Tantalum or

Aluminum capacitor (> 4.7 µF). The large capacitor can be shared by more than one device if necessary. The

small ceramic capacitor maintains low supply impedance at high frequencies while the large capacitor will act as

the charge “bucket” for fast load current spikes at the op amp output. The combination of these capacitors will

provide supply decoupling and will help keep the op amp oscillation free under any load.

SIMILAR HIGH CURRENT OUTPUT DEVICES

The LM6172 has a higher GBW of 100 MHz and over 80 mA of current output. There is also a single version, the

LM6171. The LM7372 has 120 MHz of GBW and 150 mA of current output. The LM7372 is available in an 8-pin

SO PowerPAD, and 16-pin SOIC packages with higher power dissipation.

The LME49600 buffer has 250 mA of current out and a 110 MHz bandwidth. The LME49600 is available in a

DDPAK/TO-263 package for higher power dissipation.

The LM7322 is a rail-to-rail input and output part with a slightly higher GBW of 20 MHz. It has current capability

of 40 mA sourcing and 65 mA sinking, and can drive unlimited capacitive loads. The LM7322 is available in both

VSSOP and SOIC packages.
