ISL28230FBZ中文资料Intersil数据手册PDF规格书

The ISL28130, ISL28230 and ISL28430 are single, dual and

quad micropower, low offset drift operational amplifiers that

are optimized for single and dual supply operation from 1.8V

to 5.5V and ±0.9V to ±2.75V. Their low supply current of 20µA

and rail-to-rail input/output enable the ISL28130, ISL28230,

and ISL28430 to be an excellent general-purpose op amp for a

range of applications. The ISL28130, ISL28230 and ISL28430

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

Li-ion batteries.

The ISL28130 is available in industry standard pinouts for 5 Ld

SOT-23, 5 Ld SC70 and 8 Ld SOIC packages. The ISL28230 is

available in industry standard pinouts for 8 Ld MSOP, 8 Ld

SOIC and 8 Ld DFN packages. The ISL28430 is available in

14 Ld TSSOP and 14 Ld SOIC packages. Commercial devices

operate over the temperature range of 0°C to 70°C. Full

temperature range devices operate over the temperature

range of -40°C to 125°C.
