Low Power Amplifiers Offer 6 Times More Bandwidth Than Competitors

Exar Corporation announced two industry-leading operational amplifier families, the XR1008/XR2008 and XR1009/XR2009.  The XR1008/XR2008 are single/dual amplifiers offering 75MHz bandwidth while consuming only 505µA supply current and the lower power XR1009/XR2009 single/dual amplifiers provide 35MHz at only 208µA supply current.  When compared to other competing products on the market today, the XR1008/XR2008 devices offer 6 times the bandwidth and the even lower power XR1009/XR2009 devices offer 3 times the bandwidth.

 The XR1008/XR2008 single/dual amplifiers target industrial applications such as smart meters, ultrasonic heat meters and other applications requiring high speed and low power.  The XR1009/XR2009 are single/dual amplifiers with an ultra-low 200µA supply current for portable instrumentation and applications such as interactive whiteboards.

Offering the best available combination of power consumption and performance, the XR1008/XR2008 devices help system designers meet their ever-constricting power budget without sacrificing performance. All four devices support inputs that extend 300mV beyond the negative supply voltage and provide rail-to-rail outputs. Slew rates and input voltage noise are specified at 50V/µs and 12nV/√Hz for the XR1008/XR2008 and 27V/µs and 21nV/√Hz for the XR1009/XR2009.

The XR1008, XR2008, XR1009 and XR2009 are available now in RoHS compliant, green/halogen free TSOT-5, MSOP-8 and SOIC-8 packages. 1K quantity pricing ranges from $0.51 to $0.82.
