description

The ISL28233 and ISL28433 are dual-core and quad-micro, chopper-stabilized op amps optimized for single- and dual-supply operation from 1.65V to 6.0V and ±0.825V ±3.0V. Their low supply current of 18μA and wide input range make the ISL28233, ISL28433 excellent general-purpose op amps for a wide range of applications. The ISL28233 and ISL28433 are ideal for handheld devices operating 2-cell AA batteries or single-cell Li-Ion batteries.

The ISL28233 is available in 8 LD to 8 LD for MSOP, SOIC and 8 LD DFN packages. The ISL28433 is available in 14 Ld for 14 Ld for TSSOP, SOIC and 14 Ld for 3mmx4mm TDFN packages. All devices are -40°C to +125°C over the full temperature range.
