Analog Devices Inc./Maxim Integrated MAX1300AEVKIT#

Overview

MAX1300AEVKIT# from Maxim Integrated is an evaluation kit for the MAX1300A 24-pin TSSOP 16-bit multirange successive-approximation ADC, supporting up to 115ksps throughput, ±16.5V overvoltage-tolerant analog inputs, software-programmable single-ended or differential input ranges, and SPI/QSPI/MICROWIRE-compatible serial interface. It enables rapid validation of high-precision data acquisition in industrial sensor interfaces.

For engineers reviewing the MAX1300AEVKIT# datasheet, MAX1300AEVKIT# pinout, MAX1300AEVKIT# application, or MAX1300AEVKIT# equivalent, this kit provides full hardware access to all analog input channels (CH0–CH7), reference configuration options (internal 4.096V or external 3.8–4.136V), power-supply domains (AVDD1/AVDD2/DVDD/DVDDO), and timing control signals (SCLK, CS, DIN, DOUT, SSTRB) for system-level signal integrity and conversion accuracy verification.

Technical Context

The MAX1300AEVKIT# implements a complete test platform for the MAX1300A ADC, featuring on-board voltage regulation, precision reference buffering, configurable analog input termination, and level-shifted digital I/O to support interfacing with 2.7V–5.25V host controllers. It exposes all 24 pins of the MAX1300A die in a solderable header layout with dedicated ground planes and decoupling per supply domain.

Designed for functional validation under real-world conditions, the kit supports all operating modes - external clock, internal clock, and external acquisition - and enables measurement of key dynamic parameters including SINAD (91dB), SNR (91dB), THD (-97dB), and channel-to-channel isolation (105dB) across ±3×VREF, ±6×VREF, and sub-range configurations.

FAQ

What is the primary function of the MAX1300AEVKIT#?

The MAX1300AEVKIT# is a fully assembled and tested evaluation platform for the MAX1300A 16-bit multirange SAR ADC. It provides immediate hardware access to all device pins, preconfigured power regulation, reference circuitry, and signal conditioning to accelerate functional validation, timing analysis, and dynamic performance testing of the MAX1300A in real system contexts.

Does the MAX1300AEVKIT# support both internal and external reference configurations for the MAX1300A?

Yes, the MAX1300AEVKIT# supports both reference modes. It includes a factory-trimmed 4.096V internal reference with ±1% accuracy, bypassed by a 1.0µF capacitor to AGND1, and provisions for external reference injection (3.800V–4.136V) via the REF pin, with REFCAP tied to AVDD1 to enable external mode per datasheet Figure 17.

Can the MAX1300AEVKIT# be used to evaluate differential input operation of the MAX1300A?

Yes, the MAX1300AEVKIT# supports true differential measurements using any pair of adjacent channels (e.g., CH0/CH1, CH2/CH3). Jumper-selectable termination and dedicated ground routing preserve common-mode rejection (75dB minimum), and the board's layout maintains matched trace lengths to minimize skew between differential pairs during high-speed sampling.

What digital interface protocols does the MAX1300AEVKIT# enable for the MAX1300A?

The MAX1300AEVKIT# exposes the native SPI-compatible 4-wire serial interface of the MAX1300A - CS, SCLK, DIN, DOUT - plus the SSTRB strobe output. It is compatible with standard SPI controllers, QSPI peripherals, and MICROWIRE hosts, supporting all three clocking modes (external, internal, external acquisition) as defined in the MAX1300A datasheet Figures 2–4.

How does the MAX1300AEVKIT# handle power supply separation for optimal ADC performance?

The MAX1300AEVKIT# implements strict analog/digital domain isolation: AVDD1 and AVDD2 are independently regulated and bypassed to AGND1/AGND2; DVDD powers core logic; DVDDO supplies I/O buffers. Each supply has dedicated 0.1µF ceramic decoupling, and ground planes (AGND1/AGND2/AGND3/DGND/DGNDO) are star-connected at a single point beneath the MAX1300A footprint to minimize noise coupling.
