Overview
The LTC2380-24, produced by Analog Devices Inc., is a high-performance, low-power, 24-bit successive approximation register (SAR) analog-to-digital converter (ADC). This device operates from a single 2.5V supply and features fully differential inputs, making it suitable for a wide range of applications requiring high precision and low noise. The LTC2380-24 includes an integrated digital averaging filter, which can average 1 to 65536 conversion results in real-time, significantly enhancing the dynamic range from 101dB at 1.5Msps to 145dB at 30.5sps. This ADC is known for its low power consumption of 28mW and high accuracy, achieving ±3.5ppm INL maximum with no missing codes at 24 bits.
