Analog Devices Inc./Maxim Integrated MAX11259PMB#

Overview

The MAX11259PMB# from Maxim Integrated is a fully assembled Pmod™-compatible peripheral module designed to evaluate the MAX11259AWX+, a 24-bit, 6-channel, 64ksps delta-sigma ADC with integrated PGA. It provides I²C interface capability, on-board MAX6072 2.5V voltage reference, ultra-low-noise LDO regulation, and coherent sampling support via GPIO0/CLK and GPIO1/SYNC pins for precision metrology applications.

For engineers reviewing the MAX11259PMB# datasheet, MAX11259PMB# pinout, MAX11259PMB# application, or MAX11259PMB# equivalent, this module enables rapid validation of high-resolution analog signal acquisition in industrial sensing, power quality monitoring, and portable instrumentation-especially where USB-connected standalone evaluation or FPGA-integrated full-speed I²C interfacing is required.

Technical Context

The MAX11259PMB# integrates the MAX11259AWX+ in a 36-bump WLP package and routes all critical analog and digital signals-including AIN0± through AIN5±, SCL/SDA, RSTB, RDYB, and sync-capable GPIOs-to a standard 12-pin Pmod header (J1). It supports dual reference selection (2.5V MAX6072 or 3.0V AVDD) via jumper J8 and includes configurable power domains (DVDD, AVDD, AVSS, VCOM) with dedicated jumpers (J4–J6, J2).

Hardware-level features include proven low-noise PCB layout, on-board FTDI-based USB2PMB2# interface for Windows-compatible GUI operation, and jumper-selectable I²C slave address (0x30–0x3F via JMP1/JMP2), enabling multi-device system prototyping without address conflict.

FAQ

What is the primary function of the MAX11259PMB#?

The MAX11259PMB# is a peripheral module that provides hardware and software infrastructure to evaluate the MAX11259AWX+ 24-bit delta-sigma ADC. It enables rapid I²C-based prototyping, real-time signal analysis (Scope, FFT, Histogram), and configuration of gain, reference, sampling mode, and calibration-all through a Windows GUI. The MAX11259PMB# itself contains no active silicon beyond the MAX11259AWX+ and supporting regulators/references.

Does the MAX11259PMB# support full-speed operation of the MAX11259AWX+?

The MAX11259PMB# supports full 64ksps sampling only when interfaced via user-supplied I²C (e.g., FPGA or MCU), as the onboard USB2PMB2# adapter limits standalone mode to lower sample rates and depths. Full-speed operation requires connecting SCL/SDA/RSTB/RDYB to an external controller via J1 and configuring the MAX11259PMB# in User-Supplied I²C Mode per the Quick Start guide.

How do I select between internal and external voltage references on the MAX11259PMB#?

Jumper J8 controls reference selection on the MAX11259PMB#: short J8-1 to J8-2 for the on-board MAX6072 2.5V reference; short J8-2 to J8-3 for AVDD 3.0V; or leave J8 open and connect an external reference to J8-2, then manually enter its value in the GUI's Reference Voltage field. All configurations are validated in the MAX11259PMB# schematic and jumper table.

Can the MAX11259PMB# be used for coherent sampling, and what hardware is required?

Yes-the MAX11259PMB# supports coherent sampling using its GPIO0/CLK (J9-1) and GPIO1/SYNC (J9-2) pins. A low-jitter external clock generator must be connected to J9-1, with frequency calculated via the GUI's FFT tab. The MAX11259PMB#'s hardware design-including matched trace lengths and isolated analog/digital grounds-ensures timing integrity required for accurate FFT-based performance metrics like SINAD and ENOB.

What operating systems are supported by the MAX11259PMB# GUI software?

The MAX11259PMB# GUI software is officially supported on Windows XP, Windows 7, and Windows 8.1. It requires installation of the included FTDI CDM drivers and the MAX11253_54_59EVkitSetupV1.12.exe package. No Linux or macOS native support is provided; operation on newer Windows versions (10/11) may require compatibility mode but is not guaranteed or documented by Maxim.
