Petaluma (MAXREFDES30#): 8-Channel Simultaneous-Sampling Analog Front End
Introduction<p>Three-phase power measurement applications require multiple analog inputs for voltage and current measurements on each line of the three-phase system. A power monitoring system must sample all of the analog inputs simultaneously to accurately calculate the instantaneous power consumption.<p>The Petaluma (MAXREFDES30#) subsystem reference design provides eight high-speed, 250ksps, 16-bit simultaneous-sampling analog input channels that accept ±10V input signals.<p>The Petaluma design utilizes two quadruple ultra-precision, ultra-low-noise input buffers (MAX44252); an 8-channel, 16-bit simultaneous-sampling ADC (MAX11046B); an ultra-high precision 4.096V voltage reference (MAX6126); and regulated +10V, -10V, and +5V power rails (MAX1659, MAX765/LM337, MAX8881). In addition to three-phase power measurement applications, this subsystem also performs well in any application that requires multiple simultaneous sampling of analog inputs, such as multiphase motor control and industrial vibration sensing.
