ISL28236

5MHz, Dual Precision Rail-to-Rail

Input-Output (RRIO) Op Amp

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 draw less than 1mA supply current per

amplifier while meeting excellent DC accuracy, AC

performance, noise and output drive specifications.

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

range.

Features

• 2mA Typical Supply Current

• 240µV Maximum Offset Voltage

• 6nA Typical Input Bias Current

• Down to 2.4V Single Supply Voltage Range

• Rail-to-rail Input and Output

• -40°C to +125°C Operation

• Pb-Free (RoHS compliant)

Applications

• Low-end Audio

• 4mA to 20mA Current Loops

• Medical Devices

• Sensor Amplifiers

• ADC Buffers

• DAC Output Amplifiers
