ADM560JRS

Drivers, Receivers, Transceivers Overview

The ADM560JRS is a four-driver, five-receiver RS-232 interface device manufactured by Analog Devices Inc. It operates from a single +3 V to +3.6 V power supply and supports data rates up to 116 kbps. The component integrates an on-board DC-to-DC converter that generates ±6.6 V using only four external 1 μF capacitors. It features ultralow power consumption of 1.3 mA during operation and 0.2 μA in shutdown mode. The device includes active low shutdown and receiver enable signals, allowing two receivers to remain active for peripheral monitoring. It is housed in a 28-lead Shrink Small Outline Package (SSOP) with a commercial operating temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates a charge pump voltage doubler and inverter to generate internal ±6.6 V supplies from a single +3.3 V input, eliminating the need for dual power rails.
• Features ultralow power CMOS technology with 1.3 mA operational current and 0.2 μA shutdown current for battery-sensitive applications.
• Includes dedicated control pins for active low shutdown and receiver enable, permitting selective receiver activation during low-power states.
• Provides high-level over-voltage protection on receiver inputs capable of withstanding ±25 V levels while maintaining latch-up immunity.

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Battery-operated equipment
• Peripherals

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and lead-free status. The 'J' designation indicates a commercial temperature range, while 'RS' specifies the SSOP package. Confirm RoHS compliance requirements prior to procurement as manufacturing processes may vary across different production batches and regional facilities.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing serial communication interfaces requiring minimal power consumption from a single 3.3 V source. Ensure the application utilizes four drivers and five receivers, as the ADM561 variant offers different shutdown logic. Verify that external capacitor values meet the datasheet recommendations for stable voltage generation and signal integrity at the target baud rate.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ADM560/ADM561 family of ultralow power RS-232 transceivers designed specifically for notebook PC serial ports. It serves as a direct replacement for older dual-supply solutions, offering enhanced power efficiency and simplified board layout through integrated charge pump circuitry. The device maintains compatibility with standard EIA/TIA-232 signaling protocols.
