Analog Devices Inc./Maxim Integrated MAX11665EVKIT#

Overview

MAX11665EVKIT# from Maxim Integrated is an evaluation kit for the MAX11665AUT+ 12-bit, single-channel, 500ksps low-power serial ADC in a 6-pin SOT23 package. It enables rapid characterization of DC accuracy (±1.5 LSB INL, ±4 LSB TUE), dynamic performance (73 dB SNR, 72.5 dB SINAD at 250kHz), and power efficiency (1.76 mA full-power, 1.3 µA power-down) under 2.2V–3.6V supply conditions - ideal for validating portable data-logging sensor front-ends.

For engineers reviewing the MAX11665EVKIT# datasheet, MAX11665EVKIT# pinout, MAX11665EVKIT# application, or MAX11665EVKIT# equivalent, this kit provides ready-to-use hardware for evaluating the MAX11665AUT+ ADC's SPI-compatible interface timing (t_ACQ = 52 ns, t_QUIET = 4 ns), analog input range (0V to V_DD), and low-noise acquisition in battery-powered medical instrumentation and industrial monitoring systems.

Technical Context

The MAX11665EVKIT# implements a complete test platform for the MAX11665AUT+, featuring on-board reference decoupling, configurable analog input filtering, and direct connection to host microcontrollers via standard 0.1"-spaced headers compatible with SPI/QSPI/MICROWIRE protocols. It supports full-speed operation up to 500ksps with precise aperture jitter control (15 ps) and acquisition timing validation.

Designed for the MAX11665AUT+'s 6-pin SOT23 footprint, the kit includes jumpers for V_DD, REF, and OVDD voltage selection, enabling evaluation across the full 2.2V–3.6V supply range and verification of line rejection (0.17 LSB/V) and channel-to-channel matching - critical for high-fidelity signal chain design in compact embedded systems.

FAQ

What is the primary function of the MAX11665EVKIT#?

The MAX11665EVKIT# is an evaluation kit designed exclusively for the MAX11665AUT+ 12-bit, single-channel, 500ksps SAR ADC. It provides a fully assembled PCB with signal conditioning, power regulation, and header interfaces to accelerate functional validation, timing analysis, and system integration of the MAX11665AUT+ in real-world applications such as portable data loggers and medical sensors.

Does the MAX11665EVKIT# support external reference voltage input?

No - the MAX11665AUT+ (the device evaluated by MAX11665EVKIT#) uses an internal reference derived from V_DD. While the MAX11665EVKIT# board includes circuitry compatible with REF-capable variants (e.g., MAX11666), its default configuration routes V_DD to the reference node, matching the MAX11665AUT+'s architecture and eliminating need for external reference components.

Can the MAX11665EVKIT# be used to evaluate other devices in the MAX11661–MAX11666 family?

The MAX11665EVKIT# is mechanically and electrically optimized for the 6-pin SOT23-packaged MAX11665AUT+. It is not compatible with 10-pin FMAX-packaged variants (e.g., MAX11666AUB+) due to differing pin count, layout, and dual-channel signal routing. Evaluation of those parts requires their respective kits (e.g., MAX11666EVKIT#).

What host interface standards does the MAX11665EVKIT# support?

The MAX11665EVKIT# supports direct connection to SPI, QSPI, and MICROWIRE host controllers without level shifters or glue logic. Its DOUT, SCLK, and CS signals comply with MAX11665AUT+'s timing specifications (e.g., t₄ = 15 ns data access, t₇ = 5 ns hold), enabling seamless interoperability with common microcontroller evaluation platforms.

Is the MAX11665EVKIT# RoHS-compliant and qualified for automotive use?

Yes - the MAX11665EVKIT# uses RoHS-compliant components and follows Maxim's lead-free manufacturing standards. However, it is not an automotive-qualified evaluation platform; the underlying MAX11665AUT+ is rated for –40°C to +125°C industrial operation, but the kit itself carries no AEC-Q200 or automotive qualification.
