DG403CJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG403CJ is a dual, high-speed analog switch featuring two single-pole/double-throw (SPDT) channels in a 16-pin plastic DIP package. It operates from a single +10V to +30V supply or bipolar supplies of ±4.5V to ±20V. The device guarantees low on-resistance matching between switches (2 Ω max) and on-resistance flatness over the signal range (3 Ω max). Typical on-resistance is 20 Ω with a maximum of 45 Ω for the C-grade. Switching times are 150 ns max for turn-on and 100 ns max for turn-off. It features low charge injection (15 pC max) and improved off-leakage current (<5 nA at +85°C). Power consumption is 35 µW max.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CJ' corresponds to the 0°C to +70°C temperature range and 16-pin Plastic DIP package. Confirm that the component is sourced from Analog Devices Inc./Maxim Integrated as indicated in official documentation. Ensure compatibility with single or bipolar supply voltages within the specified operational limits before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG403CJ when dual SPDT switching is required with tight on-resistance matching specifications. This part is suitable for applications demanding low power consumption and fast switching speeds. Consider the operating temperature range of 0°C to +70°C for environmental constraints. Verify that the logic input levels align with TTL or CMOS standards for the chosen supply voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG403CJ belongs to the redesigned DG401/DG403/DG405 series of improved dual high-speed analog switches. These devices utilize a 44V silicon-gate process to enhance performance metrics such as leakage current and charge injection compared to previous iterations. The DG403 variant specifically provides two SPDT switches, distinguishing it from the SPST DG401 and DPST DG405 models.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG403DJ+ serves as a direct replacement offering an extended temperature range of -40°C to +85°C in a PDIP-16 package.
