Texas Instruments 430BOOST-ADS1118

Overview

430BOOST-ADS1118 from Texas Instruments is a reference design kit built around the ADS1118 16-bit SPI-compatible ADC, integrating an internal temperature sensor, PGA, voltage reference, and oscillator in a 10-pin X2QFN (2 mm × 1.5 mm) or VSSOP package. It supports four single-ended or two differential inputs, programmable data rates from 8 to 860 SPS, and operates from 2 V to 5.5 V - enabling compact, low-power sensor measurement in space-constrained industrial and portable systems.

For engineers reviewing the 430BOOST-ADS1118 datasheet, 430BOOST-ADS1118 pinout, 430BOOST-ADS1118 application, or 430BOOST-ADS1118 equivalent, this kit provides validated hardware and firmware for rapid evaluation of thermocouple cold-junction compensation, thermistor readout, and precision analog sensing with integrated temperature monitoring.

Technical Context

The 430BOOST-ADS1118 implements a complete signal-chain reference design using the ADS1118 as its core ADC - leveraging its on-chip programmable gain amplifier (±256 mV to ±6.144 V input range), internal 0.5°C-accurate temperature sensor (0°C–70°C), and single-cycle settling architecture. The board routes all four analog inputs (AIN0–AIN3), exposes SPI interface signals (SCLK, CS, DIN, DOUT/DRDY), and includes decoupling capacitors and level-shifting support for MSP430 microcontroller integration.

It is designed specifically for TI's MSP430 LaunchPad ecosystem, providing direct header compatibility, onboard test points for analog/digital signals, and preloaded firmware demonstrating continuous and single-shot conversion modes, register configuration, and temperature-compensated K-type thermocouple measurement - all without requiring external clock or reference components.

FAQ

What is the 430BOOST-ADS1118 and how does it differ from the ADS1118 IC?

The 430BOOST-ADS1118 is a BoosterPack™ reference design board, not an IC. It integrates the ADS1118 16-bit ADC with supporting circuitry - including decoupling, level shifters, test points, and MSP430 LaunchPad-compatible headers - to enable immediate evaluation. Unlike the standalone ADS1118 IC, the 430BOOST-ADS1118 provides firmware, documentation, and hardware layout optimized for thermocouple and thermistor measurement, eliminating custom PCB design effort for initial prototyping.

Does the 430BOOST-ADS1118 support both X2QFN and VSSOP packages of the ADS1118?

Yes, the 430BOOST-ADS1118 board is designed to accommodate both the RUG (X2QFN-10) and DGS (VSSOP-10) package variants of the ADS1118. Its footprint includes pads and routing compatible with either package, allowing users to select based on thermal, size, or assembly requirements without modifying the board layout.

Can the 430BOOST-ADS1118 be used with microcontrollers other than MSP430?

Yes, the 430BOOST-ADS1118 uses standard 0.1-inch spaced headers and exposes all essential SPI signals (SCLK, CS, DIN, DOUT/DRDY), power (VDD, GND), and analog inputs (AIN0–AIN3). While optimized for MSP430 LaunchPad, it is electrically compatible with any 3.3 V or 5 V microcontroller supporting SPI communication - provided appropriate logic-level translation is applied for non-3.3 V hosts.

What thermocouple types are supported by the 430BOOST-ADS1118 reference firmware?

The official TI reference firmware for the 430BOOST-ADS1118 implements K-type thermocouple measurement using the ADS1118's integrated temperature sensor for cold-junction compensation. The hardware design supports other thermocouple types via custom firmware - but only K-type is validated and documented in the TI-provided software examples and application notes.

Is external calibration required when using the 430BOOST-ADS1118 for precision measurements?

No external calibration is required for baseline operation: the ADS1118 on the 430BOOST-ADS1118 includes factory-trimmed offset and gain error correction, and its internal temperature sensor is characterized to ±0.5°C (0°C–70°C). However, system-level calibration - such as analog input path gain matching or thermocouple linearization - may be needed for metrology-grade accuracy, and TI provides calibration routines in the reference firmware.
