Product Overview
ADM3202ARNZ-REEL7 is the narrow-SOIC version of the ADM3202 dual-channel 3.3 V RS-232 transceiver. It provides two transmitters and two receivers from a single 3.3 V supply using an internal charge pump and four external 0.1 µF capacitors.
The ARNZ suffix identifies the R-16 SOIC_N package. This is the key mechanical difference from ADM3202ARUZ-REEL7, which uses a 16-lead TSSOP.
Key Features
- Two transmitters and two receivers.
- Single 3.3 V supply.
- Four external 0.1 µF charge-pump capacitors.
- 16-lead SOIC_N package option R-16.
Functional Highlights
For this exact SKU, package selection is a critical variant axis: ARNZ and ARUZ are not footprint-equivalent even though their core electrical function is shared.
The enable/shutdown controls described for ADM3222/ADM1385 are not ADM3202 features and should not be inherited from the combined family datasheet.
Application Fit
- General-purpose RS-232 data links.
- Portable instruments.
- Two-channel serial interface stages in diagnostic equipment.
Design Considerations
- Use the R-16 SOIC_N footprint and exact ADM3202 pinout.
- Keep charge-pump capacitors close to the IC.
- Do not design around family shutdown pins absent from ADM3202.
- Verify cable and timing margin for the intended rate.
