5 GHZ DIFFERENTIAL AMPLIFIER DRIVES GIGASAMPLE ADCS ON JUST 60 MA OF QUIESCENT CURRENT

Norwood, MA (05/27/2010) - Analog Devices, Inc. (ADI), a world leader in high-performance signal processing and leading provider of amplifier and data conversion technologies, introduced today the industry’s first 5-GHz differential amplifier able to drive ADC (analog-to-digital converter) signals from DC to 1 GHz at half the power of competing products. The ADA4960-1 differential amplifier is a high-performance, low-distortion, ultra-high-speed differential amplifier effective for a wide variety of high-speed ADCs with 10-bit linearity to 500 MHz and 8-bit linearity up to 1 GHz. The ADA4960-1 differential amplifier can drive a wide variety of ADCs, such as Analog Devices’ AD9626 12-bit ADC and the AD9211 10-bit ADC.

The ADA4960-1 differential amplifier (data sheet) consumes just 60 mA of quiescent current when operating up to 1 GHz. The amplifier features a 8,700 V/μs (volts per microsecond) slew rate (AV = 6 dB, 2-V step) and wideband, low-distortion performance for frequencies up to and beyond 1 GHz, which make it effective for RF (radio frequency) and IF (immediate frequency) wired communications applications in industrial and instrumentation, defense electronics and aerospace designs. The user accessible gain adjust and bandwidth extension features allow configuration of the ADA4960-1 for line driver and channel equalization applications.
