Overview
The LTC1407CMSE-1#PBF is a high-performance, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the LTC1407 series and is known for its simultaneous sampling capability and low power consumption. It features two differential inputs that are sampled simultaneously, making it suitable for applications requiring high-speed and accurate data conversion.
The ADC operates at a sampling rate of 3 Msps (mega-samples per second) and is housed in a compact 10-lead MSOP (Micro Small Outline Package) with an exposed pad. The device is powered by a single 3V supply and includes a sleep shutdown feature that reduces power consumption to 10 μW, making it ideal for portable and battery-powered applications.
