ADG202ATQ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG202ATQ is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc. It features four independent channels with normally open configuration, housed in a 16-lead TSSOP package. The device operates on dual supplies ranging from ±4.5V to ±18V or a single supply up to 36V. Key electrical parameters include a maximum on-resistance of 200 ohms, charge injection of 20pC, and leakage current of 5nA. Switching times are specified at 600ns for turn-on and 450ns for turn-off, with an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix ATQ indicates the automotive-grade qualification and TSSOP-16 packaging variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the supplier provides traceable origin data for quality assurance purposes. Cross-reference the part number with the latest datasheet revision to confirm pinout compatibility.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low on-resistance and minimal charge injection in a compact surface-mount package. Compare against the DG202 series for potential pin-compatible alternatives if different packaging or extended temperature ranges are required. Evaluate the LC2MOS process benefits regarding power dissipation versus traditional CMOS switches for battery-operated designs.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG202ATQ belongs to the ADG202 family of LC2MOS quad SPST analog switches. This series is designed for general-purpose signal switching in industrial and automotive environments. The ATQ suffix typically denotes automotive reliability standards and specific thermal/mechanical characteristics distinct from commercial variants like the ADG202ASTZ.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG202CSE+ serves as a functional equivalent within the same product family, offering similar electrical specifications. Verify package compatibility between TSSOP and SOIC formats before substitution. Check for any differences in switching speed or leakage current that might impact sensitive circuit performance.
