The OPAx310-Q1 family of op amps includes single (OPA310-Q1), dual (OPA2310-Q1), and quad-channel (OPA4310-Q1), low-voltage (1.5V to 5.5V), high output current operational amplifiers (op amps) with rail-to-rail input and output swing capabilities. The OPA310S-Q1 variant 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-Q1 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-Q1 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-Q1 can swing very close to the rails and has a short-circuit current of 75mA minimum across temperature at 5.5V power supply. Additional output current capability can be achieved by carefully connecting multiple op amps in parallel. OPAx310-Q1 devices are an excellent choice for LED driver and other high current applications and can also be used as a reference buffer, guard amplifier, or as a discrete LDO.
The robust design of the OPAx310-Q1 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.
