DG413DJ+ - Quad SPST Analog Switch | Analog Devices
MPN： DG413DJ+ ✓ 啟用中DG413DJ+ 概覽
A CMOS analog switch is an integrated semiconductor that connects or disconnects signals under digital control. The SPST configuration provides one normally closed path per channel, while the quad architecture packages four independently controlled switches in one device. Within the broader hierarchy, DG413DJ+ is an analog switch, interface IC, and semiconductor intended for routing low-voltage analog signals in test, measurement, instrumentation, and signal-processing systems.
The improved DG413 family provides on-resistance matching between switches of 3 ohms maximum and on-resistance flatness across the signal range of 4 ohms maximum. Its 80-ohm off-state isolation specification helps prevent leakage from inactive channels, while the symmetric switch conduction allows signals to pass effectively in either direction. The operating supply range supports both dual-rail and single-rail circuit architectures.
Each channel has a separate TTL- and CMOS-compatible control input, allowing individual signal paths to be routed without changing the main analog topology. The monolithic construction also reduces the number of discrete relays or mechanical contacts required in multi-channel systems. Switching timing and leakage characteristics should be checked against the manufacturer datasheet for the exact operating conditions.
Typical uses include multimeter and test-equipment signal routing, data-acquisition front ends, sample-and-hold systems, analog measurement networks, and industrial instrumentation. The four-channel structure is particularly useful when several test points, sensor outputs, or amplifier inputs must be selected electronically under system control.
Designers should account for supply sequencing, control-logic levels, analog signal amplitude, leakage, and the power rails available to the switch. A bypass capacitor close to the supply pins helps control supply noise, while keeping sensitive analog routes short reduces susceptibility to interference. Verify that every signal remains within the absolute maximum ratings in the manufacturer datasheet.
This page combines the manufacturer product information with engineering-focused comparison data, drop-in alternatives, application guidance, and design notes. It is intended to help engineers select the correct package variant and assess whether the DG413 family matches the channel count, voltage range, logic compatibility, and precision required by a specific analog-routing design.

典型應用
DG413DJ+ 適用於 6 應用s: Multimeter and Automated Test Equipment, Data Acquisition Front Ends, Precision Signal Routing, Sample-and-Hold Systems, Industrial Sensor Interfacing, Analog Communications and Instrumentation.
Multimeter and Automated Test Equipment
The DG413DJ+ fits instrument signal-routing networks that must select among several analog test points using four independently controlled SPST paths. Its maximum on-resistance matching of 3 ohms between switches helps reduce channel-dependent error when the same measurement is routed through different paths, while 4-ohm maximum flatness limits resistance variation across the signal range. The 16-pin PDIP package also supports repairable and legacy-compatible test fixtures. Place the device near the analog input structure and use short, guarded traces to minimize pickup before precision amplification.
推薦
Data Acquisition Front Ends
The DG413DJ+ can route multiple sensor or conditioned analog inputs into a shared amplifier and converter chain. Four independent channels make it possible to select sources without changing the gain structure or connector wiring, while the 3-ohm maximum switch-to-switch matching supports more repeatable measurements. In a single-supply implementation, the device accepts 4.5 V to 20 V, allowing it to share a protected rail with compatible acquisition electronics. Validate the complete input range and control thresholds against the data-acquisition front end's signal amplitude.
推薦
Precision Signal Routing
The DG413DJ+ is appropriate for precision analog routing where several inputs must feed one downstream measurement or conversion channel. Its symmetric conduction supports effective signal passage in either direction, while the specified 3-ohm maximum matching and 4-ohm maximum flatness help preserve consistent behavior across switch states. The quad SPST architecture reduces the discrete switch count compared with four individual parts. Keep switched nodes away from switching nodes and digital clock traces, and confirm that leakage and off-state isolation remain acceptable at the lowest signal amplitude of interest.
推薦
Sample-and-Hold Systems
The DG413DJ+ can implement channel selection ahead of sample-and-hold circuitry in laboratory and industrial measurement systems. A common control sequence can select one of four analog sources before the shared hold capacitor, reducing the number of separate routing networks. The controlled on-resistance matching improves repeatability when different channels are sampled in succession, although the actual settling error also depends on source impedance, capacitance, switch timing, and the receiving amplifier. Place the switch close to the hold node and assess charge injection against the required measurement resolution.
推薦
Industrial Sensor Interfacing
The DG413DJ+ can route conditioned outputs from multiple industrial sensors into a common controller or protection circuit. Its four independent channels are useful where the system must isolate inactive inputs while maintaining consistent resistance between selected sensors. Operation from a single 4.5 V to 20 V supply simplifies compatibility with industrial signal-conditioning rails, although transient levels must remain within the absolute maximum ratings. Use a low-noise supply bypass capacitor and consider isolation or protection components when field wiring can introduce surge, ESD, or ground-potential hazards.
推薦
Analog Communications and Instrumentation
The DG413DJ+ is suitable for low-frequency analog communications and instrumentation paths that require controlled routing between several amplifier or converter stages. The quad SPST format allows independent control of receive, monitor, calibration, and auxiliary paths while maintaining a consistent 16-pin through-hole footprint. Maximum switch-to-switch on-resistance matching of 3 ohms is valuable in systems that compare channel gain or route calibration signals. The design should account for supply noise, control-logic compatibility, signal bandwidth, and the exact operating voltage using the DG413 family data sheet.

主要差異化特點
- Improved channel-to-channel resistance matching (對比MAX353CPE+)
- Single- and dual-supply operating flexibility (對比DG413DJZ)
- Four independent SPST paths in a repairable through-hole package (對比MAX353CPE+)
設計說明
Place the DG413DJ+ close to the analog source, destination amplifier, or shared measurement node. Short switched traces reduce capacitive loading, parasitic pickup, and sensitivity to nearby control signals. Keep the four switched analog paths away from high-current edges and clocks, and maintain a continuous ground reference beneath the signal path where the board layout permits.
Connect a local bypass capacitor from the device supply terminal to ground and place it adjacent to the supply pins. The capacitor should have low effective impedance over the frequency range carrying interference into the switch. Confirm that the selected voltage stays within the 4.5 V to 20 V single-supply range or the 10 V to 30 V dual-supply range, and observe the absolute maximum limits from the manufacturer data sheet.
For precision measurements, include the switch's on-resistance, matching, flatness, leakage, and switching-time effects in the complete error budget. A maximum 35-ohm on resistance can interact with source impedance and input capacitance to create settling error even when channel-to-channel matching is small. Use a low-impedance receiving amplifier and validate settling before taking a measurement.
Do not assume that a matching package makes every DG413 ordering suffix interchangeable. Verify control-input polarity and logic levels, pin orientation, supply configuration, temperature grade, and maximum analog voltage. A replacement can fit the PCB mechanically yet still change system behavior if its control thresholds, leakage, or electrical limits differ.
