Overview
The LTC1407ACMSE#PBF is a high-performance, serial 12-bit or 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the LTC1407 and LTC1407A series, which are designed for simultaneous sampling of two differential inputs at a rate of 1.5 Msps per channel. The ADCs are known for their low power consumption, drawing only 4.7 mA from a single 3V supply, and their compact 10-lead MSOP package. The devices also feature a Sleep shutdown mode that reduces power consumption to 10 µW, making them suitable for high-speed, portable applications.
