The LM7321/LM7322 are rail-to-rail input and output amplifiers with wide operating voltage and high output current. The LM7321/LM7322 are efficient, achieving a slew rate of 18 V/μs and a unity-gain bandwidth of 20 MHz while requiring only supply current per operational amplifier. The LM7321/LM7322 performance is fully specified for operation at 2.7V, ± 5V and ± 15V.
The LM7321/LM7322 are designed to drive unlimited capacitive loads without oscillation. All components of the LM7321 and LM7322 are tested at -40°C, 125°C and 25°C with modern automatic test equipment. From -40°C to 125°C, detailed specifications and extensive test high performance make it industrial, automotive and communications applications.
Larger than rail-to-rail input common-mode over this common-mode rejection dB over a wide voltage range of 50 while allowing both high-side and low-side sensing. Most device parameters are insensitive to supply voltages, which makes it easier to use in some places where supply voltages may vary, such as automotive electronics systems and battery-powered devices. These amplifiers have true rail-to-rail outputs that can provide minimal headroom current respectable (15 mA) from low distortion (0.05% THD + noise) to rail (300 mV). Each section is available in a variety of packages. The upgrade of the standard SOIC version of both parts makes existing designs easy. The LM7322 is available in a saving 8-pin MSOP package. The LM7321 comes in a small SOT23-5 package, which makes it easy to access this part of the circuit where the sensor performs better.
