Overview
The LTC2356-14, produced by Analog Devices Inc., is a high-performance, serial 14-bit analog-to-digital converter (ADC) designed for high-speed and low-power applications. This device features differential inputs, allowing for the measurement of bipolar signals ranging from –1.25V to 1.25V. The ADC operates from a single 3.3V supply, drawing only 5.5mA, and includes a Sleep mode that reduces power consumption to 13μW. The compact 10-lead MSOP package makes it ideal for portable and space-constrained designs.
