Analog Devices Unveils ADA4898 Ultra Low Noise Operational Amplifier

Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal-processing applications, introduced the ADA4898, the latest addition to its portfolio of low-noise operational amplifiers (op amps). Following the success of the ADA4899 and AD8099 operational amplifiers, the ADA4898 offers designers a unique blend of low distortion, low noise, and high speed for applications that also require high precision. Designed to work with Analog Devices’ precision data converters, including the AD7631 and AD7634, the ADA4898 is especially suited for radar-based collision avoidance, medical instrumentation and other 16-bit and 18-bit precision instrumentation applications.

Analog Devices ADA4898 Ultra Low Noise Operational Amplifier“Analog Devices continues to lead the industry in offering low-noise amplifier products. The ADA4898 is the next op amp to use the common-mode linearized input that ADI pioneered with the AD8099,” said Jim Doscher, product line director for High Speed Linear Products at Analog Devices. “The ADA4898 achieves unprecedented low ’1/f’ and broadband noise for a high-speed amplifier.”

About the ADA4898
The ADA4898 unity gain stable op amp offers design engineers ultra-low broadband noise (<1 nV/rt Hz), 1/f noise of 1.2 nV/rt Hz at 10 Hz, low distortion (–110 dBc at 500 kHz), and dc precision that optimizes the performance of analog-to-digital converters (ADCs). Particularly suited for 16- and 18-bit systems, the ADA4898 features high speed (–3 dB bandwidth of 70 MHz, at G=+1) and high slew rate (40 Volts/microsecond), providing the optimal combination of amplifier speed and precision. The ADA4898 has a wide supply range of from ±5 V to ±15 V.

Availability and Pricing
The ADA4898-1 single is now available in full production quantities in an 8-lead SOIC (small outline integrated circuit) package and is rated to operate over the extended industrial temperature range of –40°C to +125°C. A dual version will be available later this year. The ADA4898-1 is priced at $1.89 in 1,000-unit quantities.
