Smart card interface — supply range and package
The DS8023-RJX+ is a specialized smart card interface IC from Analog Devices, designed to handle the analog signal conditioning and power sequencing required for ISO 7816 smart card readers. Its 2.7V to 6V supply range covers the typical 3V and 5V smart card operating voltages, so the same IC can serve readers that support both card types without a separate regulator.
Board-fit and compliance
ROHS3 compliant per the manufacturer's declaration, so it passes the material-restriction check for EU and UKCA markets without an exemption review.
Lifecycle and procurement reality
No official successor or pin-compatible cross-reference from Analog Devices is published for this order code. If a second source is required, the parametric match must be evaluated at the board level.
