Dual and Quad Micropower, Zero-Drift, RRIO
Operational Amplifiers
ISL28233, ISL28433
The ISL28233 and ISL28433 are dual and quad
micropower, zero-drift operational amplifiers that are
optimized for single and dual supply operation from
1.65V to 5.5V and ±0.825V to ±2.75V. Their low supply
current of 18µA and wide input range enable the
ISL28233, ISL28433 to be an excellent general purpose
op amp for a 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 an 8 Ld MSOP package. The
ISL28433 is available in 14 Ld TSSOP and 14 Ld SOIC
packages. All devices operate over the temperature
range of -40°C to +85°C.

NOTES:
1. Please refer to
TB347
for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials,
and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free
soldering operations). Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the
Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), please see device information page for
ISL28233, ISL28433.
For more information on
MSL please see techbrief
