Description:
LM321 brings performance and economy to low power systems. With a high unity gain frequency and a guaranteed 0.4V/µs slew rate, the quiescent current is only 430µA/amplifier (5V). The input common-mode range includes ground and therefore the device is able to operate in single-supply applications as well as in dual supply applications. It is also capable of comfortably driving large capacitive loads.
The LM321 is available in the SOT23-5 package. Overall the LM321 is a low power, wide supply range performance op-amp that can be designed into a wide range of applications at an economical price without sacrificing valuable board space.
Each amplifier is biased from an internal−voltage the regulator which has a low-temperature coefficient thus giving each amplifier good temperature characteristics as well as excellent power supply rejection.
The LM321 op-amp can operate with a single or dual power supply voltage, has true-differential inputs, and remain in the linear mode with an input common-mode voltage of 0 VDC.
LM321 has a class B output stage, which is comprised of push−pull transistors. This type of output is inherently subject to crossover distortion near mid−rail where neither push or pull transistors are conducting. Several techniques can be used to minimize crossover distortion.
This amplifier operates over a wide range of power supply voltages, with little change in performance characteristics. At a 25˚C amplifier, the operation is possible down to a minimum supply voltage of 3V.
