Analog Devices Inc. presents the LTC2345HUK-18, an 18-bit Analog to Digital Converter featuring a Successive Approximation Register (SAR) architecture. This component offers 8 differential inputs and a sampling rate of 200kSPS, configured as a Sample-and-Hold (S/H) Multiplexer Analog-to-Digital Converter (MUX-ADC) with an 8:1 ratio. The data interface supports LVDS and SPI serial protocols. Key features include simultaneous sampling capabilities and flexible reference options, supporting both external and internal references. The device operates within a supply voltage range of 4.75V to 5.25V for both analog and digital supplies, and is specified for operation across an extended temperature range of -40°C to 125°C. Packaged in a 48-QFN (7x7) with an exposed pad, the LTC2345HUK-18 is suitable for surface mounting and finds application in various industrial and data acquisition systems.
