These devices feature an Input Range Enhancement Circuit (IREC) which enables them to maintain CMRR performance for input voltages 10% above the positive supply rail and to 100mV below the negative supply. The output operation is rail-to-rail.
The ISL28288 and ISL28488 draw minimal supply current while meeting excellent DC-accuracy, AC-performance, noise and output drive specifications. The ISL28288 (10 Ld MSOP only) contains a power-down enable pin that reduces the power supply current to typically less than 4µA in the disabled state.
- Low power 60µA typical supply current
- 1.5mV max offset voltage
- 30pA max input bias current
- 250kHz typical gain-bandwidth product
- 105dB typical PSRR
- 100dB typical CMRR
- Single supply operation down to 2.4V
- Input is capable of swinging above V+ and below V- (ground sensing)
- Rail-to-rail input and output (RRIO)
- Enable Pin - ISL28288 10 Ld MSOP package option only
- Pb-free (RoHS compliant)
