Exar Corporation announced two industry-leading operational amplifier families, the XR1008/XR2008 and XR1009/XR2009. The XR1008/XR2008 are single/dual amplifiers offering 75 MHz bandwidth while consuming only 505 µA supply current and the lower power XR1009/XR2009 single/dual amplifiers provide 35 MHz at only 208 µA 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 200 µA 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 300 mV beyond the negative supply voltage and provide rail-to-rail outputs. Slew rates and input voltage noise are specified at 50 V/µs and 12 nV/√Hz for the XR1008/XR2008 and 27 V/µs and 21 nV/√Hz for the XR1009/XR2009.
