WS72551/2 WS72551/WS72552 Zero-Drift, Single-Supply, Rail-to-Rail Input/Output Operational Amplifiers Http//:www.willsemi.com Descriptions This family of amplifiers has ultra low offset, drift, and bias current. The WS72551 and WS72552 are SOT23-5L SOP-8L MSOP-8L single and dual amplifiers featuring rail-to-rail input and output swings respectively. All are guaranteed to operate from 2.5V to 5V with a single supply. OUT 1 V- 2 +IN 3 5 V+ 4 -IN +IN 1 V- 2 -IN 3 5 V+ 4 OUT The WS72551/WS72552 provides the benefits previously found only in expensive auto-zeroing or SOT23-5L SOT23-5L chopper-stabilized amplifiers. These new zero-drift (WS72551EA-5/TR) (WS72551E-5/TR) amplifiers combine low cost with high accuracy. No external capacitors are required. With an offset voltage of only 3μV and drift of 0.008 NC 1 8 NC OUTA 1 -IN 2 7 V+ -INA 2 +IN 3 6 OUT V- 4 5 NC μV/°C, the WS72551/WS72552 are perfectly suited +INA 3 V- 4 A B 8 V+ 7 OUTB 6 -INB 5 +INB for applications in which error sources cannot be tolerated. Temperature, position and pressure SOP-8L/MSOP-8L sensors, medical equipment, and strain gauge SOP-8L/MSOP-8L Pin configuration (Top view) amplifiers benefit greatly from nearly zero drift over their operating temperature range. The rail-to-rail input and output swings provided by the WS72551/WS72552 make both high-side and low-side sensing easy. 2551 GAYW 2551 GEYW WLSI 2551 GSYW SOT23-5L SOT23-5L SOP-8L 2551 GMYW WLSI 2552 GSYW 2552 GMYW MSOP-8L SOP-8L MSOP-8L The WS72551/WS72552 are specified for the extended industrial/automotive temperature range (-40°C to +125°C). The WS72551 single amplifier is available in 8-lead MSOP, 8-lead narrow SOIC and 5-lead SOT23-5L packages. The WS72552 dual amplifier is available in 8-lead MSOP and 8-lead narrow SOIC surface mount packages.
