FEATURES  
DESCRIPTION  
234  
•
SUPERIOR SOUND QUALITY  
The OPA1641 (single), OPA1642 (dual), and  
OPA1644 (quad) series are JFET-input, ultralow  
distortion, low-noise operational amplifiers fully  
specified for audio applications.  
•
TRUE JFET INPUT OP AMP  
WITH LOW INPUT BIAS CURRENT  
•
•
•
•
•
•
LOW NOISE: 5.1nV/√Hz at 1kHz  
ULTRALOW DISTORTION: 0.00005% at 1kHz  
HIGH SLEW RATE: 20V/μs  
The OPA1641, OPA1642, and OPA1644 rail-to-rail  
output swing allows increased headroom, making  
these devices ideal for use in any audio circuit.  
Features include 5.1nV/√Hz noise, low THD+N  
(0.00005%), a low input bias current of 2pA, and low  
quiescent current of 1.8mA per channel.  
UNITY GAIN STABLE  
NO PHASE REVERSAL  
LOW QUIESCENT CURRENT:  
1.8mA per Channel  
These devices operate over a very wide supply  
voltage range of ±2.25V to ±18V. The OPA1641,  
OPA1642, and OPA1644 series of op amps are  
unity-gain stable and provide excellent dynamic  
behavior over a wide range of load conditions.  
•
•
•
RAIL-TO-RAIL OUTPUT  
WIDE SUPPLY RANGE: ±2.25V to ±18V  
SINGLE, DUAL, AND QUAD VERSIONS  
AVAILABLE  
The dual and quad versions feature completely  
independent circuitry for lowest crosstalk and  
freedom from interactions between channels, even  
when overdriven or overloaded.
