LN8552
The LN8551, LN8552 and LN8554 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 LN8551 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 LN855X family make both high-side and low- side sensing easy.
The LN855X series is specified for the extended industrial/automotive (–40°C to +125°C) temperature range. The LN8551 single is available in 5-lead SOT and 8-lead SOP/MSOP packages. The LN8552 dual amplifier is available in 8-lead SOP/MSOP packages. The LN8554 quad is available in narrow 14-lead SOP and 14-lead TSSOP packages.
