Product details
Overview
MAX11213EVKIT+ from Maxim Integrated is an evaluation kit for the MAX11213 ultra-low-power, 16-bit delta-sigma ADC with programmable gain (1–128) and four SPI-controlled GPIOs. It supports single-channel differential analog input, internal oscillator (2.048/2.4576 MHz), >100 dB 50/60 Hz line-noise rejection, and operates from 2.7V–3.6V AVDD and 1.7V–3.6V DVDD. Designed for sensor measurement in industrial 4–20 mA loops.
For engineers reviewing the MAX11213EVKIT+ datasheet, MAX11213EVKIT+ pinout, MAX11213EVKIT+ application, or MAX11213EVKIT+ equivalent, this page provides verified hardware configuration details, supported ADC operating modes (single-cycle vs. continuous), GPIO control mapping, on-board reference and signal buffering options, and calibration workflow integration - all essential for rapid prototyping of high-accuracy, low-power sensor interfaces.
Technical Context
The MAX11213EVKIT+ implements the MAX11213 ADC in a fully assembled, tested QSOP-16 footprint with onboard voltage regulation, configurable reference (internal/external), jumper-selectable input buffering (AINP/AINN and REFP/REFN), and header-accessible GPIO1–GPIO4. It supports both internal oscillator (LINEF-selectable) and external clock modes via CLK pin.
Hardware design includes SPI interface termination, RDY/DOUT status monitoring, SCLK/DIN/CS routing to standard 0.1"-spaced headers, and provision for unipolar/bipolar input range selection. The kit enables full validation of self-calibration (offset/gain), system calibration, and digital gain scaling (1–128) under real-world source impedance and noise conditions.

FAQ
What is the primary function of the MAX11213EVKIT+?
The MAX11213EVKIT+ is a fully assembled evaluation platform for the MAX11213 16-bit delta-sigma ADC. It enables hardware validation of key features including programmable gain (1–128), four SPI-configurable GPIOs, internal oscillator operation, 50/60 Hz line-noise rejection, and on-demand calibration routines - all critical for low-power, high-accuracy sensor interface design.
Does the MAX11213EVKIT+ support both MAX11203 and MAX11213 devices?
No - the MAX11213EVKIT+ is specifically configured for the MAX11213, which includes digital programmable gain (1–128). While pin-compatible with the MAX11203, the kit's default firmware, jumpers, and documentation assume MAX11213 functionality. Using it with MAX11203 requires manual register configuration to disable gain-related features.
How is the MAX11213's internal oscillator configured on the MAX11213EVKIT+?
The MAX11213EVKIT+ supports both internal oscillator modes via the LINEF bit in CTRL1: LINEF = 0 selects 2.4576 MHz (optimized for 60 Hz rejection), LINEF = 1 selects 2.048 MHz (optimized for 50 Hz rejection). No external components are required; the internal oscillator is enabled by default and can be overridden by applying an external clock to the CLK pin.
Can the MAX11213EVKIT+ be used to evaluate input buffering and reference buffering?
Yes - the MAX11213EVKIT+ provides solder-jumper options to independently enable or disable signal input buffers (AINP/AINN) and reference input buffers (REFP/REFN). This allows direct evaluation of how buffering affects dynamic range, linearity, and compatibility with high-impedance transducers - matching the MAX11213's SIGBUF and REFBUF register controls.
What calibration workflows are supported by the MAX11213EVKIT+?
The MAX11213EVKIT+ supports full calibration execution: on-demand self-calibration (200 ms, corrects internal offset/gain), system zero-scale calibration (100 ms, requires external 0-V input), and system full-scale calibration (100 ms, requires external full-scale input). All are accessible via SPI commands documented in the MAX11213EVKIT+ user guide and validated using the kit's onboard test points and GPIO-controlled mux examples.
