Product Overview
ADM3202ARUZ-REEL7 is the TSSOP ordering option of Analog Devices’ dual-channel 3.3 V RS-232 transceiver. It provides two transmitters and two receivers and uses an internal voltage doubler/inverter with four external 0.1 µF capacitors.
The ARUZ suffix maps to the RU-16 TSSOP package. That distinction matters when comparing it with ADM3202ARNZ, which uses a 16-lead narrow SOIC even though both belong to the same electrical family.
Key Features
- Two RS-232 transmit channels and two receive channels.
- Single 3.3 V supply with internal charge-pump conversion.
- Four external 0.1 µF charge-pump capacitors.
- 16-lead RU-16 TSSOP package.
Functional Highlights
Package is the main exact-variant distinction for ARUZ. A footprint selected from a nearby ARN or ARW order code will not match this part.
Shutdown circuitry described for ADM3222 and ADM1385 should not be assigned to ADM3202; the combined family datasheet must be read at the exact device level.
Application Fit
- General-purpose dual-channel RS-232 data links.
- Portable instruments.
- Legacy serial interfaces requiring two transmit and two receive paths.
Design Considerations
- Use the RU-16 TSSOP footprint and verify the exact pin map.
- Place all four charge-pump capacitors close to the device.
- Do not assign ADM3222/ADM1385 shutdown behavior to ADM3202.
- Check cable and timing margin for the required serial rate.
