Powervoltage-Feedback Amp Achieves Industry’s Best Combination Of Performance And Power says ADI
Analog Devices has introduced what is said to be 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 minimises 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.
