OPAx990 40-V Rail-to-Rail Input/Output, Low Offset Voltage, Low Power Op Amp  
1 Features  
3 Description  
The OPAx990 family (OPA990, OPA2990, and  
OPA4990) is a family of high voltage (40-V) general  
purpose operational amplifiers. These devices offer  
excellent DC precision and AC performance,  
including rail-to-rail input/output, low offset (±300 µV,  
typ), and low offset drift (±0.6 µV/°C, typ).  
1
Low offset voltage: ±300 µV  
Low offset voltage drift: ±0.6 µV/°C  
Low noise: 30 nV/Hz at 1 kHz  
High common-mode rejection: 115 dB  
Low bias current: ±10 pA  
Unique features such as differential and common-  
mode input voltage range to the supply rail, high  
short-circuit current (±80 mA), high slew rate (4.5  
V/µs), and shutdown make the OPAx990 an  
extremely flexible, robust, and high-performance op  
amp for high-voltage industrial applications.  
Rail-to-rail input and output  
MUX-friendly/comparator inputs  
Amplifier operates with differential inputs up to  
supply rail  
Amplifier can be used in open-loop or as  
comparator  
The OPAx990 family of op amps is available in micro-  
size packages (such as X2QFN, WSON, and SOT-  
553), as well as standard packages (such as SOT-23,  
SOIC, and TSSOP), and is specified from –40°C to  
125°C.  
Wide bandwidth: 1.1-MHz GBW  
High slew rate: 4.5 V/µs  
Low quiescent current: 120 µA per amplifier  
Wide supply: ±1.35 V to ±20 V, 2.7 V to 40 V  
Robust EMIRR performance: 78 dB at 1.8 GHz
