Description
The ISL28433 is a quad micropower, chopper stabilized operational amplifier that is optimized for single and dual supply operation from 1.65V to 6.0V and ± 0.825V to ± 3.0V. Their low supply current of 18µA and wide input range enable the ISL28433 to be an excellent general-purpose op amp for a wide range of applications. The ISL28433 is ideal for handheld devices that operate off 2 AA or single Li-ion batteries. The ISL28433 is available in 14 Ld TSSOP, 14 Ld SOIC and 14 Ld 3mm x 4mm TDFN packages. The device operates over the temperature range of -40 °C to +125 °C.
