3 Description

The OPAx310 family of op amps includes single

(OPA310), dual (OPA2310), and quad-channel

(OPA4310), low-voltage (1.5 V to 5.5 V), 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 0.9-μs

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 75-mA 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

3 MHz and can drive up to 250 pF of cap load

with no sustained oscillations, enabling designers

to achieve both improved performance and a lowerpower

consumption.
