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.
