Best-in-Class Voltage Feedback Amplifier Offers Low Distortion and Noise Using Only 5 mA Supply Current
The ADA4857-1 (single) and ADA4857-2 (dual) voltage feedback amplifiers set a new low power standard for low distortion and low noise op amps. These devices offer the best combination of speed (850 MHz, 2700 V/µs), low noise (4.4 nV/√Hz), and low distortion (–91 dBc @ 10 MHz) in the industry on just 5 mA of supply current—the lowest power consumption in the class and at least 50% less power than competitive amplifiers. The ADA4857 family also offers up to 50% less heat dissipation to minimize passive and active thermal management design issues that require heat sinks, cooling fans, etc. The devices are based on Analog Devices' new third generation XFCB-3™ (eXtra fast complementary bipolar) high voltage silicon germanium process. The ADA4857-1 is available in 8-lead LFCSP and 8-lead SOIC packaging and the dual ADA4857-2 is available in 16-lead LFCSP. All packages include an exposed paddle that provides a low thermal resistance path to the PCB—enabling more efficient heat transfer and increasing reliability.
