OPAx992 40-V Rail-to-Rail Input/Output, Low Offset Voltage, Low Noise Op Amp  
1 Features  
3 Description  
•

•
Low offset voltage: ±210 µV  
The OPAx992 family (OPA992, OPA2992, and  
OPA4992) 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 (±210 µV, typ), low  
offset drift (±0.25 µV/°C, typ) and low noise (7 nV/√Hz  
at 1 kHz, 4.4 nV/√Hz at 10 kHz).  
Low offset voltage drift: ±0.25 µV/°C  
Low noise: 7 nV/√Hz at 1 kHz, 4.4 nV/√Hz  
broadband  
High common-mode rejection: 115 dB  
Low bias current: ±10 pA

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  
Wide bandwidth: 10.6-MHz GBW, unity-gain stable  
High slew rate: 32 V/µs  
Low quiescent current: 2.4 mA per amplifier  
Wide supply: ±1.35 V to ±20 V, 2.7 V to 40 V  
Robust EMIRR performance  
Features such as differential and common-mode input  
voltage ranges to the supply rails, high short-circuit  
current (±65 mA), and high slew rate (32 V/µs) make  
the OPAx992 a flexible, robust, and high-performance  
op amp for high-voltage industrial applications.

The OPAx992 family of op amps is available in micro-  
size packages (such as WSON), as well as standard  
packages (such as SOT-23, SOIC, and TSSOP), and  
is specified from –40°C to 125°C.
