Beschreibung von OPA4310
The OPAx310 family of op amps includes single (OPA310), dual (OPA2310), and quad-channel (OPA4310), low-voltage (1.5V to 5.5V), high output current operational amplifiers (op amps) with rail-to-rail input and output swing capabilities. The OPAx310S also features a very fast shutdown response and has a typical enable time of 0.9µs that allows for power savings when the application involves duty cycling the amplifier signal chain. OPAx310 family has a robust ESD performance with fail safe input ESD structure where there are no diodes connected from inputs to the positive power supply rail.
OPAx310 is offered in power pad, standard, small size package variants and has an internal current limit protection, thermal shutdown protection that enables additional robustness when operating with high output current. OPAx310 can swing very close to the rails and has a short-circuit current of 75mA minimum across temperature at 5.5-V power supply. Additional output current capability can be achieved by carefully connecting multiple op amps in parallel. OPAx310 devices are an excellent choice for LED driver, LCD driver, laser driver, TEC driver applications and can also be used as a reference buffer, guard amplifier, or as a discrete LDO.
The robust design of the OPAx310 family simplifies circuit design. These op amps feature an integrated RFI and EMI rejection filter with no-phase reversal in input overdrive conditions. These devices also deliver excellent AC performance with a gain bandwidth of 3MHz and can drive up to 250pF of capacitor load with no sustained oscillations, enabling designers to achieve both improved performance and a lower-power consumption.
