Analog Devices Inc./Maxim Integrated MAX1162EVKIT

Overview

MAX1162EVKIT from Maxim Integrated is an evaluation kit designed to accelerate development and validation of the MAX1162 16-bit, +5V, 200ksps successive-approximation ADC. It supports full characterization of dynamic performance (SINAD up to 89.5dB, SFDR up to 103dB), low-power operation (10µA shutdown), SPI/QSPI/MICROWIRE interface timing, and analog input behavior (0–VREF range, 4MHz input bandwidth) in battery-powered data-acquisition systems.

For engineers reviewing the MAX1162EVKIT datasheet, MAX1162EVKIT pinout, MAX1162EVKIT application, or MAX1162EVKIT equivalent, this kit enables rapid prototyping of precision analog front-ends for industrial I/O modules, thermocouple/accelerometer measurement circuits, and motor control feedback loops - with on-board reference buffering, configurable power supplies, and direct µP interface headers.

Technical Context

The MAX1162EVKIT implements a complete test platform for the MAX1162 ADC, including a stable +5V analog supply (AVDD), adjustable digital supply (DVDD = +2.7V to +5.25V), buffered 4.096V reference, and low-noise analog signal path with 4MHz small-signal bandwidth. It replicates real-world acquisition conditions using the internal track-and-hold circuit and supports full 24-clock serial readout at up to 4.8MHz SCLK.

Board-level features include jumper-selectable power modes (normal/autoshutdown), CS-controlled conversion initiation, DOUT timing validation (tDO ≤ 100ns), and layout-optimized grounding (separate AGND/DGND star point at pin 3). The kit validates critical ADC behaviors: acquisition time (tACQ = 1.1µs), aperture jitter (<50ps), and INL performance (±2 LSB max for MAX1162B grade).

FAQ

What is the primary function of the MAX1162EVKIT?

The MAX1162EVKIT is a fully assembled evaluation board that enables hardware and firmware validation of the MAX1162 16-bit SAR ADC. It provides all necessary power regulation, reference buffering, signal conditioning, and microcontroller interface headers to characterize DC accuracy (INL ±2 LSB), dynamic performance (SINAD 89.5dB), and low-power operation (10µA shutdown) without custom PCB design. Engineers use the MAX1162EVKIT to verify system-level timing, noise immunity, and interface compatibility before committing to production layout.

Does the MAX1162EVKIT support both µMAX and DFN package variants of the MAX1162?

Yes, the MAX1162EVKIT includes a socketed footprint compatible with both the 10-pin µMAX (MAX1162BCUB+) and 10-pin DFN (MAX1162BC_B*) package variants of the MAX1162 ADC. The board's layout adheres to Maxim's recommended grounding scheme - with separate AGND/DGND planes tied at a single star point - and maintains signal integrity for both packages per the MAX1162 datasheet layout guidelines. No hardware modification is required to evaluate either variant using the MAX1162EVKIT.

Can the MAX1162EVKIT be used to validate SPI, QSPI, and MICROWIRE interfaces simultaneously?

Yes, the MAX1162EVKIT supports all three serial protocols via identical pin assignments (CS, SCLK, DOUT) and configurable jumpers. It validates CPOL=0/CPHA=0 timing for SPI and MICROWIRE, and high-speed 4.8MHz QSPI operation with proper setup/hold margins (tCSS ≥ 100ns, tCSH = 0ns). The board includes test points for probing SCLK-to-DOUT delay (tDO ≤ 100ns) and CS-controlled wakeup (1.1µs acquisition), confirming interoperability with host controllers such as PIC16 SSP modules, ARM SPI peripherals, and FPGA soft-core interfaces - all using the same MAX1162EVKIT hardware.

What reference voltage options are supported on the MAX1162EVKIT?

The MAX1162EVKIT supports both internal and external reference configurations. It ships with a factory-trimmed 4.096V reference (MAX6126AESA) bypassed with a 4.7µF tantalum capacitor, meeting the MAX1162's requirement for <10Ω output impedance and ≤100µA load current. An alternative REF header allows connection of precision external references (e.g., REF5040, ADR4540) within the 3.8V to AVDD range. The board's REF trace is routed with low-inductance geometry and dedicated AGND return to minimize noise coupling - directly enabling validation of reference-dependent parameters like gain error (±0.01% FSR) and THD (-90dB).

How does the MAX1162EVKIT help optimize analog input signal conditioning?

The MAX1162EVKIT includes a dedicated AIN signal path with 0.1µF ceramic bypassing to AGND, 4MHz bandwidth verification capability, and provisions for external op-amp buffering (e.g., MAX44260). It validates key design constraints: source impedance ≤1kΩ to meet 1.1µs acquisition time (tACQ), slew rate ≥2V/µs for multiplexed inputs, and anti-alias filtering integration. By measuring actual INL vs. code and SINAD vs. frequency on the MAX1162EVKIT, engineers confirm whether their front-end amplifier, filter, and layout choices preserve the MAX1162's specified 16-bit linearity and 89.5dB dynamic range - eliminating guesswork in production design.
