AD7606 , AD7607 simultaneous-sampling ADCs

Analog Devices introduced (analog-to-digital converters) that simplify the design of next-generation power-line-monitoring systems. The need for more efficient utility substations and “smart grid” management is growing as worldwide electricity demand increases.
AD7606 , AD7607 simultaneous-sampling ADCs provide the resolution and performance needed for next-generation power-line-monitoring system designs that ensure the reliable delivery of electricity to millions of people in nearly all corners of the world,” said Leo McHugh, product line director, precision signal processing, Analog Devices. “
Available in six- or four-channel options, ADI’s 16-bit, eight-channel AD7606 and 14-bit, eight-channel AD7607 simultaneous-sampling ADCs achieve SNR (signal-to-noise ratio) performance of 90 dB.
The AD7606 and AD7607 simultaneous-sampling ADCs operate on a 5-V analog supply, 1.8-V to 5-V logic supply, and feature a front-end, anti-alias filter with high input impedance and input clamp to ±16.5-V. In addition, an internal reference and a reduced decoupling capacitor requirement provide a higher level of integration compared to alternative solutions. The new devices offer true bipolar analog input ranges of ±5 V and ±10 V that allow for the preservation of phase information while sampling bipolar voltages and currents over a wide dynamic range.
The AD7606 and AD7607 simultaneous-sampling ADCs contain on-chip LDOs (low-drop-out regulators), a reference and reference buffer, track-and-hold circuitry, signal-conditioning circuitry, on-chip conversion clock, and high-speed parallel and serial interfaces. The AD7606 and AD7607 simultaneous-sampling ADCs integrate a front-end, anti-alias filter with attenuation of approximately 40 dB while sampling at a fast throughput rate up to 200 kSPS. The conversion process and data acquisition are controlled using CONVST signals and an internal oscillator. Two CONVST pins allow the simultaneous sampling of all eight analog inputs or two groups of four analog input channels to allow for phase differences
