The ISL28236 is a low-power dual operational amplifier

optimized for single supply operation from 2.4V to 5.5V,

allowing operation from one lithium cell or two Ni-Cd batteries.

The device features a gain-bandwidth product of 5MHz.

The ISL28236 features an Input Range Enhancement Circuit

(IREC), which enables the amplifier to maintain CMRR

performance for input voltages greater than the positive

supply. The input signal is capable of swinging 0.25V above the

positive supply and to the negative supply with only a slight

degradation of the CMRR performance. The output operation

is rail-to-rail.

The part typically draws less than 1mA supply current per

amplifier while meeting excellent DC accuracy, AC

performance, noise and output drive specifications. The

ISL28236 is available in the 8 Ld SOIC and the 8 Ld MSOP.

Operation is guaranteed over the -40°C to +125°C

temperature range.
