Mingjiada Supply ADI LTC1861 And LTC1865 Series µPower Analog To Digital Converters

With the rapid proliferation of portable smart devices, remote sensing and monitoring, and low-power industrial terminals, the market has come to demand that analogue-to-digital converters (ADCs) meet a range of stringent requirements, including high precision, ultra-low power consumption, compact size and exceptional stability. Traditional ADCs generally suffer from issues such as high standby power consumption, insufficient precision and limited applicability, making it difficult to meet the long-term operational requirements of battery-powered devices.

In response to the pressing needs of the low-power precision data acquisition market, Mingjiada Electronics has newly launched ADI’s original LTC1861 / LTC1865 series of micro-power analogue-to-digital converters (ADCs). With a sampling rate of 250 ksps, low power consumption, a compact MSOP package and an SPI-compatible serial interface, this series is an ideal choice for industrial control, portable instruments, battery-powered devices and multi-channel data acquisition systems.

Both the LTC1861 and LTC1865 belong to ADI’s micro-power successive approximation register (SAR) ADC series. Specifically:
LTC1861: 12-bit resolution, 250 ksps sampling rate, dual-channel input;
LTC1865: 16-bit resolution, 250 ksps sampling rate, dual-channel input.
Both are powered by a single 5V supply, support an external reference voltage and feature an auto-shutdown function, enabling them to enter a low-power sleep mode between conversions, thereby significantly extending the battery life of battery-powered systems.

Key Features
High resolution and medium-to-high-speed sampling: 12-bit for the LTC1861 and 16-bit for the LTC1865, up to 250 ksps;
Ultra-low-power design: typical operating current as low as the milliampere range, with a shutdown current as low as 1.5 µA;
Dual-channel input: supports single-ended or differential input configurations, suitable for multi-channel signal acquisition;
Serial interfaces: Compatible with SPI, QSPI and MICROWIRE, facilitating connection to MCUs and DSPs;
Compact packaging: The LTC1861 is housed in an MSOP-8 package, whilst the LTC1865 is housed in an MSOP-10 package;
Wide temperature range: Commercial and industrial temperature options are available to suit harsh environments;
Automatic shutdown: Automatically enters a low-power mode upon completion of conversion, reducing the system’s average power consumption.

Applications
The LTC1861 / LTC1865 series is suitable for a wide range of low-power, high-precision data acquisition applications, including:
Industrial automation and process control;
Portable instruments and battery-powered devices;
Medical and life sciences instrumentation;
Multi-channel sensor interfaces;
Data acquisition cards and embedded systems;
Communications and signal processing systems;
Remote monitoring and smart sensing terminals.
The LTC1861 is the ideal choice for designs requiring 12-bit precision and cost optimisation; whilst for applications requiring higher 16-bit precision, the LTC1865 offers superior measurement resolution.
