Overview
The LTC2450IDC#TRMPBF is an ultra-tiny 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the LTC2450 series and is known for its compact design and high precision. It operates on a single 2.7V to 5.5V supply and features a delta-sigma modulator as its converter core. The ADC is housed in a 6-pin, 2mm × 2mm DFN package with an exposed pad, making it ideal for space-constrained applications. The LTC2450IDC#TRMPBF is designed for ease of use, with an integrated oscillator that eliminates the need for external components and a proprietary input sampling scheme that significantly reduces average input sampling current.
