SDC1740-411 Description

The SDC1740-411 from Analog Devices Inc. is a high-precision 14-bit S/D (Sigma-Delta) Converter designed for demanding analog-to-digital conversion applications. This obsolete yet robust IC features a parallel data interface and operates on a dual ±15V and 5V supply, making it suitable for mixed-signal systems requiring both analog and digital voltage domains. Packaged in a 32DIP through-hole format, it offers three channels for multi-channel data acquisition. With EAR99 ECCN classification and ROHS3 compliance, it meets stringent environmental and export control standards. Though discontinued, its 14-bit resolution and REACH-unaffected status ensure reliability in legacy or long-lifecycle systems.
