LTC1867AIGN#TRPBF

Updated: 2026-07-20

Overview

The LTC1867AIGN#TRPBF is a 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Linear Technology, now part of Analog Devices. It is designed for high-precision applications requiring low power consumption and compact size. The device operates with a single 5V supply and features a serial interface for easy integration with microcontrollers and digital signal processors. This ADC is housed in a small SSOP-16 package, making it suitable for space-constrained applications. Its high accuracy and low noise performance make it a popular choice in industrial automation, medical instrumentation, and automotive systems where precise analog signal measurement is critical.

Structure and Working Principle

The LTC1867AIGN#TRPBF utilizes a SAR architecture, which sequentially approximates the input analog voltage to produce a digital output. The internal circuitry includes a sample-and-hold amplifier, a comparator, and a DAC (digital-to-analog converter) to achieve high-resolution conversion. The device features a unipolar input range of 0V to VREF (reference voltage), with a typical conversion time of 1.25μs. It communicates via a 3-wire SPI-compatible interface, allowing for easy connection to most microcontrollers. The low power consumption (typically 1.5mW at 5V) makes it suitable for battery-powered applications.
