Product details
Overview
The MAX1231BEVSYS# is a complete evaluation system from Maxim Integrated designed to characterize the MAX1231B 12-bit, 4-channel, 300ksps SPI analog-to-digital converter. It comprises a USB-powered master board (MAX116XXSPIMB) and a dedicated daughter board pre-installed with the MAX1231BEEG+ ADC, featuring on-board 2.5V reference, 10MHz SPI interface, and Windows XP/Vista/7-compatible GUI software for time/frequency/histogram analysis.
For engineers reviewing the MAX1231BEVSYS# datasheet, MAX1231BEVSYS# pinout, MAX1231BEVSYS# application, or MAX1231BEVSYS# equivalent, this system enables rapid validation of 12-bit SAR ADC performance-including RMS, frequency, min/max, and DC calculations-across sensor signal conditioning, industrial data acquisition, and precision instrumentation prototypes without external power or hardware modification.
Technical Context
The MAX1231BEVSYS# integrates a Spartan-3A FPGA (Xilinx XC3S50A) and MAXQ2000 microcontroller to generate precise SPI timing and manage ADC register configuration, supporting all four scan modes and averaging up to 32 samples per conversion. It delivers configurable single-ended or differential input operation across 4 analog channels with user-selectable reference sources (internal 2.5V or external).
Hardware-level signal integrity is ensured via proven PCB layout, on-board ferrite bead filtering (TDK MMZ1608R301A), and dedicated LDOs (MAX1793EUE50+, MAX1983EUT+) for clean 3.6V, 2.5V, 5V, and 1.2V rail generation-enabling stable evaluation of the MAX1231B under real-world noise and supply-voltage variation conditions.

FAQ
What is the primary function of the MAX1231BEVSYS#?
The MAX1231BEVSYS# is a complete evaluation system for the MAX1231B 12-bit, 4-channel, 300ksps SPI ADC. It includes a USB-connected master board and a daughter board pre-populated with the MAX1231BEEG+ device, enabling immediate characterization of conversion accuracy, noise, linearity, and timing behavior using included Windows-compatible software with time-domain, frequency-domain, and histogram analysis tools.
Does the MAX1231BEVSYS# require an external power supply?
No-the MAX1231BEVSYS# is fully USB-powered via its MAX116XX SPI master board. The daughter board draws regulated 3.6V or 5V from the master board depending on JU1 jumper position. External power is optional and only needed if overriding default supply rails via the VDD test point, with supported range of 3.6V to 5.5V.
Which ADC variants can be evaluated using the MAX1231BEVSYS#?
The MAX1231BEVSYS# is specifically configured for the MAX1231B, but its daughter board supports pin-compatible replacement with other members of the MAX1230/MAX1231 family. Free samples of alternate devices (e.g., MAX1230) may be requested from Maxim for direct substitution-no PCB changes required due to identical 16-pin QSOP footprint and SPI register map compatibility.
What software capabilities does the MAX1231BEVSYS# provide?
The MAX1231BEVSYS# includes Windows XP/Vista/7-compatible GUI software that supports real-time data capture, time-domain waveform display, FFT-based frequency analysis, statistical histogram generation, and automated calculation of RMS, frequency, min/max, average DC, mean, and standard deviation. It allows up to one million samples per acquisition and supports configurable scan modes, averaging (up to 32 samples), and input type selection (single-ended/differential).
How is voltage reference configured on the MAX1231BEVSYS# daughter board?
The MAX1231BEVSYS# daughter board uses the onboard MAX6126AASA25+ 2.5V reference by default (JU2 shunt at 2–3). To use an external reference-such as 4.096V for 5V-supply ADCs-remove the JU2 shunt and connect the reference to the REF+ test point, or install a compatible reference IC at U3 and set JU2 to 1–2. Reference voltage directly determines ADC full-scale range and code-to-voltage conversion accuracy.
