Analog Devices Inc. LTC2389IUK-18 is an 18-bit Analog-to-Digital Converter (ADC) featuring a Successive Approximation Register (SAR) architecture. This single-channel device offers a high sampling rate of 2.5MSPS with a 1:1 Sample-and-Hold ratio. The LTC2389IUK-18 supports both differential and pseudo-differential input types, configurable for selectable address functionality. Data output is available via SPI or parallel interfaces, and it accommodates both internal and external reference types. Operating within a -40°C to 85°C temperature range, this component is housed in a 48-QFN (7x7) package with an exposed pad, suitable for surface mount applications. Analog supply and digital supply voltages range from 4.75V to 5.25V. This component is widely utilized in data acquisition systems, medical imaging, and high-speed test and measurement equipment.
