Analog Devices Inc./Maxim Integrated MAX1193EVKIT

Overview

MAX1193EVKIT from Maxim Integrated is an evaluation kit designed to accelerate development and characterization of the MAX1193 ultra-low-power, dual 8-bit, 45Msps analog-to-digital converter. It provides full access to the 28-pin thin QFN ADC's differential analog inputs (INA+/INA−, INB+/INB−), parallel CMOS-compatible tri-state outputs (D0–D7, A/B), clock interface (CLK), and reference configuration pins (REFP/REFN/COM/REFIN). The kit supports internal, buffered external, and unbuffered external reference modes and enables real-time dynamic performance validation-including SINAD (48.5dB at 5.5MHz), SFDR (70dBc), and power consumption (57mW at 45Msps)-in ultrasound imaging and IQ baseband sampling applications.

For engineers reviewing the MAX1193EVKIT datasheet, MAX1193EVKIT pinout, MAX1193EVKIT application, or MAX1193EVKIT equivalent, this kit delivers production-representative signal integrity, configurable power-down modes (shutdown: 0.1µA), flexible digital I/O supply (1.8V–3.6V), and verified timing compliance with tDOA/tDOB ≤ 8.5ns and aperture jitter ≤ 2psRMS-critical for high-fidelity undersampling and portable instrumentation design.

Technical Context

The MAX1193EVKIT implements a seven-stage fully differential pipelined ADC architecture with 5-cycle latency for Channel A and 5.5-cycle latency for Channel B. It validates the device's dual-channel simultaneous sampling on CLK rising edge, multiplexed output timing, and A/B channel indicator synchronization with ≤6ns delay.

It supports all three reference configurations: internal (1.024V bandgap, ±30ppm/°C), buffered external (1.024V ±10% applied to REFIN), and unbuffered external (REFP/REFN/COM driven externally at ±0.256V around VDD/2). The kit enables verification of input bandwidth (440MHz small-signal, 440MHz full-power) and interchannel matching (±0.05dB amplitude, ±0.2° phase at 11MHz).

FAQ

What is the primary function of the MAX1193EVKIT?

The MAX1193EVKIT is a fully assembled evaluation platform for the MAX1193 dual 8-bit, 45Msps ADC. It enables hardware validation, dynamic performance testing (SINAD, SFDR, THD), reference configuration verification, and timing margin analysis-without requiring custom PCB design. The kit includes all necessary decoupling, clock conditioning, and analog input termination to replicate production-level signal integrity for the MAX1193.

Does the MAX1193EVKIT support all three reference modes of the MAX1193?

Yes, the MAX1193EVKIT supports internal, buffered external, and unbuffered external reference configurations as specified for the MAX1193. Jumper-selectable options allow users to configure REFIN tied to VDD (internal), apply 1.024V to REFIN (buffered), or ground REFIN while driving REFP/REFN/COM externally-enabling accurate full-scale range validation across all operating modes defined in the MAX1193 datasheet.

Can the MAX1193EVKIT be used to verify interchannel matching specifications?

Yes, the MAX1193EVKIT provides matched analog input paths and synchronized clock distribution to validate the MAX1193's interchannel specifications: amplitude matching (±0.05dB) and phase matching (±0.2°) at 11MHz, as well as crosstalk rejection (−75dB). These measurements are supported by the kit's low-noise layout, calibrated signal sources, and dual-channel FFT analysis capability via included software tools.

What power supply requirements does the MAX1193EVKIT have?

The MAX1193EVKIT requires two independent supplies: a 2.7V–3.6V analog rail for the MAX1193's VDD pins and a 1.8V–3.6V digital rail for OVDD. On-board regulators and filtering ensure clean, low-noise operation. The kit draws ≤60mA from the analog supply and ≤5mA from the digital supply under full 45Msps operation-matching the MAX1193's published IDD and IODD values.

Is the MAX1193EVKIT compatible with standard FPGA or microcontroller interfaces?

Yes, the MAX1193EVKIT exposes the MAX1193's parallel CMOS-compatible tri-state outputs (D0–D7, A/B) with configurable OVDD (1.8V–3.6V), enabling direct connection to Xilinx/Intel FPGA I/O banks, ARM Cortex-M parallel interfaces, or ASIC data buses. The A/B channel indicator and precise timing (tDOA/tDOB ≤ 8.5ns) simplify synchronous capture logic implementation without additional glue logic.
