Zero-Drift, Single-Supply,
Rail-to-Rail Input/Output Operational Amplifiers
ELN8551/8552/8554
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.
