Applications
The ADM202JNZ is widely used in industrial RS-232 serial communication interfaces, embedded system UART-to-RS232 level translation, and legacy serial port extensions for microcontrollers and DSPs. It is common in test and measurement equipment, industrial PLCs, and legacy serial terminal adapters where reliable EIA-232-E compliant signal levels are needed from a single 5 V supply. Embedded systems engineers use it to add RS-232 ports to 5 V microcontroller designs without a separate negative voltage supply.

Frequently Asked Questions
How does ADM202JNZ generate RS-232 voltage levels from a single 5 V supply without external negative rail?
The ADM202JNZ uses an internal charge pump with external 0.1 µF capacitors to generate the ±10 V RS-232 output levels required by EIA-232-E standard. This eliminates the need for a separate negative power supply, simplifying the PCB power tree in 5 V microcontroller-based serial communication designs.
What receiver input protection does ADM202JNZ provide on RS-232 lines to handle industrial cable environments?
ADM202JNZ receiver inputs feature Schmitt trigger hysteresis thresholds, improving noise immunity for RS-232 signals on long cable runs up to several meters. The receivers also tolerate input voltages up to ±25 V, providing protection against typical RS-232 cable overvoltage transients in industrial environments.
Is ADM202JNZ a drop-in pin-compatible alternative to MAX202 in existing RS-232 interface PCB designs?
Yes. ADM202JNZ is pin-compatible with MAX202 and other industry-standard dual RS-232 transceivers sharing the 16-pin DIP pinout, operating with the same 4 external 0.1 µF charge pump capacitors from a 5 V supply. This makes it a direct replacement option for board-level RS-232 transceiver upgrades or legacy inventory substitutions.
