Foreword
Portable instruments and meters are rapidly evolving towards miniaturisation, low power consumption and high precision. From handheld medical monitoring devices to portable data acquisition systems, and from battery-powered field testers to wearable health devices, digital-to-analogue converters (DACs) serve as the core components for analogue signal output, and their performance directly determines the accuracy and battery life of the entire device.
Shenzhen Mingjiada Electronics Co., Ltd. (hereinafter referred to as ‘Mingjiada Electronics’), as a globally renowned authorised independent distributor of electronic components, maintains a long-term stock of the full range of digital-to-analogue converter (DAC) chips from Texas Instruments (TI). The following provides a detailed overview of the TI DAC product series that Mingjiada Electronics prioritises for procurement and supply for portable instrument applications, to assist R&D engineers and procurement personnel in making rapid product selections.
I. Core Requirements for DACs in Portable Instruments
Portable instruments are typically battery-powered, placing the following core requirements on DAC chips:
Ultra-low power consumption: Power consumption per channel must be kept at the milliwatt or even microwatt level to extend the device’s battery life
Small-sized packaging: To accommodate compact PCB layouts and save valuable board space
High precision and monotonicity: To ensure the accuracy and stability of the analogue output signal
Wide operating voltage range: Compatibility with common battery voltages such as 2.7V to 5.5V
TI’s DAC product range performs exceptionally well across these dimensions; below are the five product series prioritised for procurement by Mingjiada.
