The ISL28233 and ISL28433 are dual and quad micropower,

chopper stabilized operational amplifiers that are optimized for

single and dual supply operation from 1.8V to 6.0V and ±0.825V

to ±3.0V. Their low supply current of 18µA and wide input range

enable the ISL28233, ISL28433 to be excellent general purpose

op amps for a wide range of applications. The ISL28233 and

ISL28433 are ideal for handheld devices that operate off 2 AA or

single Li-ion batteries.

The ISL28233 is available in 8 Ld MSOP, 8 Ld SOIC and 8 Ld DFN

packages. The ISL28433 is available in 14 Ld TSSOP, 14 Ld SOIC

and 14 Ld 3mmx4mm TDFN packages. All devices operate over

the temperature range of -40°C to +125°C.
