Analog Devices Inc./Maxim Integrated MAX1132EVKIT

Overview

MAX1132EVKIT from Maxim Integrated is an evaluation kit for the MAX1132 16-bit, 200ksps analog-to-digital converter with integrated +4.096V reference, internal track/hold, and SPI/QSPI/MICROWIRE-compatible serial interface. It supports ±12V bipolar or 0 to +12V unipolar input ranges, operates from a single +5V supply, and delivers ≥85dB SINAD at 200ksps in industrial data-acquisition systems.

For engineers reviewing the MAX1132EVKIT datasheet, MAX1132EVKIT pinout, MAX1132EVKIT application, or MAX1132EVKIT equivalent, this kit enables rapid validation of the MAX1132 ADC's dynamic performance, software-configurable input range selection, on-demand calibration, three programmable logic outputs (P0–P2), and SSTRB-synchronized timing with TMS320 DSPs.

Technical Context

The MAX1132EVKIT implements the full signal chain for the MAX1132 ADC, including precision analog front-end scaling, REF/REFADJ/CREF bypassing (2.2µF/0.22µF/1µF), AGND/DGND separation, and buffered digital I/O routing. It supports all three clock modes (internal, external short-acquisition, external long-acquisition) and provides test points for AIN, REF, SCLK, DOUT, DIN, CS, SHDN, and SSTRB.

Designed for direct interfacing with microcontrollers and DSPs, the kit exposes the MAX1132's three user-programmable CMOS outputs (P0–P2) for external multiplexer or PGA control, and includes hardware jumpers to configure unipolar/bipolar mode, INT/EXT clock selection, and power-down activation via SHDN.

FAQ

What is the primary function of the MAX1132EVKIT?

The MAX1132EVKIT is a fully assembled and tested evaluation platform for the MAX1132 16-bit, 200ksps ADC. It enables engineers to verify the device's dynamic performance (≥85dB SINAD), validate input range configuration (±12V/0–+12V), test on-demand calibration, and evaluate timing behavior-including SSTRB synchronization with TMS320 DSPs-without custom PCB design.

Does the MAX1132EVKIT support both internal and external clock modes for the MAX1132?

Yes, the MAX1132EVKIT supports all three clock configurations specified for the MAX1132: internal clock mode (SSTRB strobes conversion start/end), external short-acquisition mode (24-clock cycles), and external long-acquisition mode (32-clock cycles). Jumpers and test points allow direct access to SCLK, CS, and SSTRB signals for oscilloscope-based timing analysis of the MAX1132.

Can the MAX1132EVKIT be used to evaluate the MAX1132's programmable logic outputs (P0–P2)?

Yes, the MAX1132EVKIT provides direct access to P0, P1, and P2 pins via test points and includes circuitry to drive external loads such as 8-channel analog multiplexers or programmable gain amplifiers. These outputs are controlled by bits 0–2 of the MAX1132's 8-bit Control Byte and retain their state during hardware/software shutdown as specified in the MAX1132 datasheet.

How does the MAX1132EVKIT handle reference voltage configuration for the MAX1132?

The MAX1132EVKIT implements the exact reference configuration required by the MAX1132: a 2.2µF capacitor at REF, 0.22µF at REFADJ, and 1µF at CREF. It supports both internal reference operation (4.096V nominal) and external reference mode (3.0V–4.2V), with jumpers to disable the internal buffer by pulling REFADJ to AVDD-matching the MAX1132's documented reference architecture.

Is the MAX1132EVKIT compatible with standard microcontroller SPI interfaces?

Yes, the MAX1132EVKIT is fully SPI-compatible and works with standard microcontroller SPI peripherals without level-shifting or external logic. It adheres to MAX1132's timing requirements: MSB-first data format, DOUT updated on SCLK falling edge, DIN latched on rising edge, and CS-driven enable/disable-enabling immediate integration with ARM Cortex-M, PIC, and other SPI-capable MCUs for rapid firmware validation of the MAX1132.
