General Description

The  ELN8551, ELN8552  and  ELN8554  are  single,  dual and  quad  amplifiers  featuring  rail-to-rail  input  and Output swings, which has ultralow offset, drift and bias current.
All are guaranteed to operate from +2.7 V to +5 V Single supply. With  an  offset  voltage  of  only  3  µV  and  drift  of  20 nV/°C, the ELN8551 is perfectly suited for Applications where  error  sources  cannot  be  tolerated.
Temperature, position and pres-sure sensors, medical equipment  and strain gage amplifiers benefit greatly from nearly zero drift over their operating temperature range.
The rail-to-rail input  and  output  swings  provided  by  the  ELN8551/358/324 family make both high-side and low-side sensing easy.
The  ELN8551/358/324 series  is  specified  for  the  extended industrial/automotive (–40°C to +125°C) temperature range.
The ELN8551 single is available in  5-lead SOT and 8-lead SOP/MSOP packages.
The ELN8552 dual amplifier is available  in  8-lead  SOP/MSOP  packages.
The ELN8554 quad  is  available  in narrow 14-lead  SOP  and  14-lead TSSOP packages.
