Other Application Hints
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 (> 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 OUTPUT DEVICES
The LM7332 is a dual rail-to-rail amplifier with a slightly lower GBW capable of sinking and sourcing 100 mA. It is
available in SOIC and VSSOP packages.
The LM4562 is dual op amp with very low noise and 0.7 mV voltage offset.
The LME49870 and LME49860 are single and dual low noise amplifiers that can work from ±22 volt supplies.
OTHER HIGH PERFORMANCE SOT-23 AMPLIERS
The LM7341 is a 4 MHz rail-to-rail input and output part that requires only 0.6 mA to operate, and can drive
unlimited capacitive load. It has a voltage gain of 97 dB, a CMRR of 93 dB, and a PSRR of 104 dB.
The LM6211 is a 20 MHz part with CMOS input, which runs on ±12 volt or 24 volt single supplies. It has rail-to-
rail output and low noise.
The LM7121 has a gain bandwidth of 235 MHz.
