Operating at 850 MHz, the ADA4857 high-speed op amp consumes 5 mA, less than half the power of competing voltage-feedback amps, while featuring the industry's most well-balanced combination of performance specifications.
NORWOOD, Mass. (Business Wire EON) February 19, 2008 --
Analog Devices, Inc. (ADI), a global leader in high-performance
semiconductors for signal processing applications and market leader in
amplifier ICs, today introduced the lowest power voltage-feedback
amplifier in its class, making it ideal for densely populated, thermally
sensitive instrumentation equipment that requires high-speed signal
conditioning. Operating at 850 MHz, the ADA4857
high-speed op
amp consumes 5 mA, less than half the power of competing
voltage-feedback amps, while featuring the industry’s
most well-balanced combination of performance specifications.
The ADA4857 reduces input noise to 4.4 nV/rtHz, which is 50 percent
lower than competing amps. With –91-dBc
distortion at 10 MHz, the new amplifier provides a 10-dB improvement
over voltage-feedback amps that dissipate twice the power. For
space-constrained medical imaging, ATE and other multichannel
instruments, the 5 mA supply current minimizes the need for active
thermal management devices and passive cooling elements, such as fans
and heat sinks, thus allowing system designers to reduce development
costs and design complexity.
Pricing and Availability
The ADA4857 is sampling now with full volume production scheduled for
April 2008. The single-channel ADA4857-1 is available in 3-mm ×
3-mm 8-lead LFCSP (lead-frame chip-scale package) and 8-lead SOIC
(small-outline IC) packages. The dual ADA4857-2 is available in a 4-mm ×
4-mm 16-lead LFCSP. The single-channel ADA4857-1 is priced at $0.85 per
unit, and the dual ADA4857-2 is priced at $1.39 per unit, both in
1,000-unit quantities. For more information, visit http://www.analog.com/pr/ADA4857-1.
