Petaluma (MAXREFDES30#): 8-Channel Simultaneous-
Sampling Analog Front End
Apr 28, 2014
Abstract: The Petaluma (MAXREFDES30#) subsystem reference design is a cost optimized, high-speed and high-accuracy analog
measurement solution for three-phase power monitoring applications. Hardware, firmware, design files, and lab measurements
provide complete system information for rapid prototyping and development.
Introduction
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.
The Petaluma (MAXREFDES30#) subsystem reference
design provides eight high-speed, 250ksps, 16-bit
simultaneous-sampling analog input channels that accept
±10V input signals.
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.
