Analog Devices Delivers Industry’s Fastest Four-Channel 16-Bit SAR ADC

Affordably priced AD7655 offers high speed and accuracy for multi-channel and multiplexed applications.

Norwood, MA - The AD7655 is the newest member of Analog Devices’ family of PulSAR™ high-performance successive approximation register (SAR) analog-to-digital converters (ADCs). The low priced AD7655 combines four 16-bit channels of the industry’s fastest conversion into a low-profile 48-lead LQFP or LFCSP package. For use in multi-channel and multiplexed applications that demand accuracy, small package size, and low cost, it guarantees a combination of specifications that, until now, was unavailable at this price: 4 input channels, 1 MSPS sampling rate, 86 dB SNR at 100 kHz, single-supply operation, and a 0-5 V analog input range. Two on-chip low-noise, wideband track-and-hold amplifiers, each preceded by a two-channel multiplexer, provide simultaneous sampling capability.


Applications

With no pipeline delay, this PulSAR ADC is ideal for applications using multi-channel data acquisition, and zero-latency control loops in industrial process control, test and measurement and motor control systems. Power consumption scales with throughput rate.


Pricing and Availability

The AD7655 operates within the –40 to +85 degrees C temperature range. It is sampling now in 48-lead LQFP and LFCSP packages and is priced at $7.99 per unit in 1,000-piece quantities.
