SBOS701D – DECEMBER 2015 – REVISED AUGUST 2021  
OPAx191 36-V, Low-Power, Precision, CMOS, Rail-to-Rail Input/Output,  
Low Offset Voltage, Low Input Bias Current Op Amp  
1 Features  
3 Description  
Low offset voltage: ±5 µV  
The OPAx191 family (OPA191, OPA2191, and  
OPA4191) is a new generation of 36-V, e-trim™  
operational amplifiers.  
Low offset voltage drift: ±0.1 µV/°C  
Low noise: 15 nV/√ Hz at 1 kHz  
High common-mode rejection: 140 dB  
Low bias current: ±5 pA  
Rail-to-rail input and output  
Wide bandwidth: 2.5-MHz GBW  
High slew rate: 5 V/µs  
Low quiescent current: 140 µA per amplifier  
Wide supply: ±2.25 V to ±18 V, 4.5 V to 36 V  
EMI/RFI filtered inputs  
Differential input voltage range to supply rail  
High capacitive load drive capability: 1 nF  
Industry standard packages:  
These devices offer outstanding dc precision and  
ac performance, including rail-to-rail input/output, low  
offset voltage (±5 µV, typ), low offset drift (±0.2 µV/°C,  
typ), and 2-MHz bandwidth.  
Unique features, such as differential input-voltage  
range to the supply rail, high output current (±65 mA),  
high capacitive load drive of up to 1 nF, and high  
slew rate (5 V/µs), make the OPAx191 a robust, high-  
performance operational amplifier for high-voltage  
industrial applications.  
– Single in SOIC-8, SOT-5, and VSSOP-8  
– Dual in SOIC-8 and VSSOP-8  
– Quad in SOIC-14, TSSOP-14, and WQFN-16  
The OPAx191 family of op amps is available in  
standard packages and is specified from –40°C to  
+125°C.
