DATASHEET  
ISL28127, ISL28227, ISL28227SEH  
Precision Single and Dual Low Noise Operational Amplifiers  
FN6633  
Rev 8.00  
April 1, 2016  
The ISL28127, ISL28227 and ISL28227SEH are very high  
Features  
precision amplifiers featuring very low noise, low offset  
voltage, low input bias current and low temperature drift  
making them the ideal choice for applications requiring both  
high DC accuracy and AC performance. The combination of  
precision, low noise and small footprint provides the user with  
outstanding value and flexibility relative to similar competitive  
parts.  
• Low input offset voltage . . . . . . . . . . . . . . . . . . . . ±70µV, max  
ISL28227SEH ±75µV, max  
• Superb offset voltage TC. . . . . . . . . . . . . . . . . .0.5µV/°C,max  
ISL28227SEH 1µV/°C, max  
• Wide supply range . . . . . . . . . . . . . . . . . . . . . . . . . .4.5V to 40V  
ISL28227SEH 4.5V to 36V  
Applications for these amplifiers include precision active  
filters, medical and analytical instrumentation, precision  
power supply controls and industrial controls.  
• Very low voltage noise. . . . . . . . . . . . . . . . . . . . . . . . .2.5nV/Hz  
• Input bias current. . . . . . . . . . . . . . . . . . . . . . . . . . ±10nA, max  
• Gain-bandwidth product . . . . . . . . . .10MHz Unity gain stable  
• No phase reversal  
The ISL28127 single and ISL28227 dual are available in 8 Ld  
SOIC, TDFN and MSOP packages. All devices are offered in  
standard pin configurations and operate over the extended  
temperature range to -40°C to +125°C.  
• Operating temperature range. . . . . . . . . . . .-40°C to +125°C  
ISL28227SEH -55°C to +125°C  
The ISL28227SEH is available in a 10 Ld hermetic ceramic  
Flatpack package. The device is offered in an industry  
standard pin configuration and operates over the extended  
temperature range from -55°C to +125°C.
