Overview
The LTC1407IMSE#PBF is a high-performance analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the LTC1407 series, which includes 12-bit and 14-bit versions, and is known for its simultaneous sampling capability and low power consumption. The LTC1407IMSE#PBF specifically is a 12-bit or 14-bit ADC, depending on the variant, with two 1.5Msps simultaneously sampled differential inputs. It operates from a single 3V supply, drawing only 4.7mA, and features a Sleep shutdown mode that reduces power consumption to 10µW. This makes it highly suitable for high-speed, portable applications.
