5V, Rail-Rail I/O, Zero-Drift, Programmable Gain  
Instrumentation Amplifiers  
ISL28533, ISL28534, ISL28535, ISL28633, ISL28634, ISL28635  
The ISL28533, ISL28534, ISL28535, ISL28633, ISL28634,  
and ISL28635 are 5V Zero-Drift Rail-to-Rail Input/Output  
Programmable Gain Instrumentation Amplifiers (PGIA). These  
instrumentation amplifiers feature low offset, low noise, low  
gain error and high CMRR. They are ideal for high precision  
applications over the wide industrial temperature range.  
Features  
• Ultra high precision front end amplifier  
• Zero drift instrumentation amplifier  
• Pin selectable 9 gain settings: G = 1 to 1,000  
• Rail-to-Rail input/output  
These Instrumentation Amplifiers are designed with a unique  
2-bit, 3-state logic interface that allows up to 9 selectable gain  
settings. The ISL2853x single-ended output includes and  
additional uncommitted zero-drift amplifier, useful to buffer  
the REF input or used as a precision amplifier. The ISL2863x  
differential output amplifier includes a reference pin to set the  
common mode output voltage to interface with differential  
input ADCs.  
• Single ended output (ISL28533, ISL28534, ISL28535)  
• Differential output (ISL28633, ISL28634, ISL28635)
