The AD7606 and AD7607 are simultaneous-sampling ADCs (analog-to-digital converters) that simplify the design of next-generation power-line-monitoring systems. The AD7606 and AD7607 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 devices also feature low-noise, high-input-impedance (independent of sample rate), signal scaling amplifiers that provide 10-kHz input bandwidth (–3-dB), and 1 MO analog input impedance with only 0.1% gain error, and 0.01% offset error. 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 between transformers…
