Analog Devices puts to fore the dual version of its popular ADA4898-1 operational amplifier in the form of the ADA4898-2. Similar to the ADA4898-1, the ADA4898-2 dual-channel, high-speed op amp brings to designers a fusion of low distortion, ultra-low noise and high speed effective for applications that need high precision signal processing.
The dual channel version helps reduce the size of the packaging and also maintains performance. It has been designed to work with Analog Devices’ precision data converters such as 18-bit, differential programmable input PulSAR ADCs (analog-to-digital converters), the AD7631 and AD7634.
Furthermore, the ADA4898-2 is a unity-gain-stable op amp that offers engineers ultra-low broadband noise, 1/f noise of 1.2 nV/rt Hz at 10 Hz, low distortion (–110 dBc at 500 kHz), and dc precision for optimized performance of ADCs.
The ADA4898-2 works well with16-bit and 18-bit systems and features elevated speed and slew rate. It also supports a broader range of voltage supply, ±5 V to ±15 V. Each per thousand prices of ADA4898-1 and ADA4898-2 is $1.89 and $3.21 respectively.

Analog Devices today broadened its new fourth generation SHARC family, the industry’s highest-performance floating-point digital signal processors, by introducing a series of processors for industrial and instrumentation, automotive audio, and home theater applications. The SHARC processors introduced today are: the 21469 (industrial temperature range packaging) for industrial and instrumentation; the 21469W, 21465W, and 21462W for automotive audio; and the 21467 for home theater. Like their predecessors, this newest generation of SHARC processors is based on a single-instruction multiple-data (SIMD) core that supports 32-bit fixed-point as well as 32-/40-bit floating-point arithmetic formats, making them particularly suitable for high-performance applications.
The new SHARC processors will be available to sample in Q1 2009. Pricing is $31.50 in quantities of 1,000 for the ADSP-21469 at 450 MHz, while the 400 MHz ADSP-21469 lists at $28.50 for 1,000 pieces.
