NORWOOD, Mass. -- (Business Wire)
Analog
Devices, Inc. (NASDAQ: ADI), a global leader in high-performance
semiconductors for signal processing applications, today introduced a
family of low-power
rail-to-rail amplifiers for high-speed data acquisition systems that
require exceptional accuracy, precision and power efficiency. For system
designers who are looking to achieve full datasheet specifications from high
resolution A/D converters, the ADA4805-1 (single) and ADA4805-2
(dual) amplifiers provide the only solution with quiescent current as
low as 495µA. The amplifiers’ Dynamic Power Scaling (DPS) feature allows
users to dynamically manage the power consumption by shutting-down the
amplifier between analog-to-digital converter samples. This further
reduces by up to 90 percent the power consumption — with no performance
degradation —when compared to similar solutions. Watch this video to
learn more about the industry’s most power efficient A/D converter
drivers http://www.analog.com/ada4805video
The 100-MHz ADA4805-1 and ADA4805-2 amplifiers achieve a high slew rate
of 160 V/μs, low noise (5.9 nV/√Hz at 100 kHz) and low distortion (−102
dBc/−116 dBc HD2/HD3 at 100 kHz) while consuming only 1.5 mW of power.
The amplifiers are designed for power-sensitive portable and
battery-powered data acquisition devices, such as handheld or portable
test and measurement instruments, battery-powered industrial equipment
and remote environmental monitoring devices. They can also be used to
reduce power and thermal dissipation in high-density applications such
as cellular base stations and medical imaging equipment.
With exceptionally low offset-voltage drift of 1.5µV/°C maximum (0.2μV / 0C
typical), the ADA4805 family offers eight times lower drift performance
than competing high-speed (100MHz) amplifiers. The combination of
superior ac and dc performance allow designers to enhance system
sensitivity, dynamic range and overall system accuracy.
The ADA4805-1/-2 amplifiers have a wide voltage range, supporting 3-V
supplies, and in applications that require a wider dynamic range can
also operate on supplies as high as +/-5V.
