DG413DY+ - 4-Channel SPST CMOS Analog Switch | Analog Devices
MPN: DG413DY+ ✓ نشطDG413DY+ نظرة عامة
An analog switch is an integrated circuit that connects or disconnects signal paths under digital control. The DG413DY+ belongs to the CMOS analog switch hierarchy, where each of its four single-pole, single-throw channels can independently route a source terminal to one of two possible signal paths. This makes the device useful when a system must select among sensors, measurement channels, test points, or external circuit branches without introducing mechanical relays.
Key features include four independent SPST switches, 1:1 signal routing, a maximum on-resistance of 45 Ω, low on-resistance matching between switches of 3 Ω maximum, and on-resistance flatness of 4 Ω maximum over the signal range. The device uses CMOS-compatible control inputs and supports improved conduction in either signal direction. These characteristics help preserve signal integrity in precision measurement, test, instrumentation, and communication circuits.
The DG413 family uses an enhanced CMOS process to combine low power dissipation, high switching speed, and low on resistance. Because the switches provide equal electrical performance in both directions, a PCB designer can use consistent routing practices for paired signal paths. The manufacturer emphasizes improved matching and flatness because these characteristics directly influence gain error, channel-to-channel variation, and the accuracy of analog measurements passing through the switch.
Typical uses include battery-powered instrumentation, automated test equipment, data-acquisition systems, communication routing, sample-and-hold front ends, and precision sensor interfaces. The DG413DY+ can support acquisition of multiple analog inputs where each channel requires independent selection while keeping control logic compatible with modern CMOS systems. Its four-channel structure reduces the number of separate switch packages needed in a typical measurement front end.
When laying out the circuit, route each switched signal through a symmetric path and keep digital control traces away from sensitive analog nodes. Confirm the actual supply voltage, input-signal range, switch logic levels, and absolute maximum ratings in the manufacturer datasheet before connecting external circuitry. The 16-SOIC footprint also allows board updates where the four analog channels can replace discrete or multiplexed switching arrangements.
This page combines the DG413DY+ electrical characteristics, pin-compatible alternatives, package information, and application guidance to support faster component selection and implementation. It also highlights the distinctions between resistance matching, resistance flatness, signal range, and channel count that matter when choosing an analog switch for precision routing.

التطبيقات النموذجية
DG413DY+ مناسب لـ 6 التطبيقs: Automated Test Equipment Signal Routing, Data Acquisition Front Ends, Precision Sensor Multiplexing, Battery-Powered Instrumentation, Communication Signal Routing, Sample-and-Hold Signal Selection.
Automated Test Equipment Signal Routing
The DG413DY+ suits automated test equipment because four independent SPST channels can route one analog node to two possible destinations without mechanical switching. Its 45 Ω maximum on resistance, 3 Ω maximum matching between switches, and 4 Ω maximum flatness help maintain predictable test-channel behavior. Place the device between the source and measurement path, keep analog traces short, and include switch resistance in the test accuracy calculation.

Data Acquisition Front Ends
In a data-acquisition front end, the DG413DY+ can independently select among several analog sensor or conditioning paths. The four SPST channels reduce component count, while 1:1 routing preserves signal polarity. Its 4 Ω maximum on-resistance flatness limits signal-dependent resistance change, and 3 Ω maximum matching limits channel-to-channel variation. Select source impedances that remain acceptable with the 45 Ω maximum switch resistance.
موصى به
Precision Sensor Multiplexing
The DG413DY+ can route outputs from multiple sensor channels into a shared amplifier or converter when independent selection and consistent resistance are important. Its bidirectional conduction supports whichever signal polarity the selected source uses, while the matching specification limits gain variation between channels. Keep sensitive sensor traces away from control inputs, observe the 4.5 V to 30 V listed signal range, and verify whether the sensor amplitude falls within the valid operating region.
موصى به
Battery-Powered Instrumentation
The DG413DY+ is useful in compact, battery-powered instruments that must switch several low-bandwidth analog signals while keeping control logic compatible with CMOS systems. Four independently controlled channels provide flexible routing in a 16-SOIC surface-mount package. The switch conducts equally well in either direction, which simplifies paired routing layouts. Validate the actual supply-voltage range and leakage in the DG413 Data Sheet (Rev. 7) before sizing the power budget.
موصى به
Communication Signal Routing
The DG413DY+ can provide low-rate analog routing in communication equipment when a compact, digitally controlled four-channel SPST arrangement is sufficient. The 1:1 topology supports straightforward source-to-destination selection, and equal conduction in both directions avoids orientation-dependent behavior. Designers should compare the 45 Ω maximum on resistance against line impedance, verify bandwidth and insertion-loss requirements, and keep switching-control transitions away from sensitive analog traces.
موصى به
Sample-and-Hold Signal Selection
The DG413DY+ can present one of two signal choices to a downstream sample-and-hold or measurement circuit using its SPST channels. Matching of 3 Ω maximum helps reduce gain differences among selected channels, while flatness of 4 Ω maximum limits resistance changes across the signal range. For a single high-precision channel, confirm that 45 Ω maximum is sufficiently low; otherwise, evaluate the 35 Ω maximum option identified as DG413DY-E3.

ملاحظات التصميم
Include the 45 Ω maximum on resistance in the analog path's voltage-divider calculation. For a 10 kΩ source, the maximum nominal ratio is approximately 45 Ω divided by 10,045 Ω, or about 0.45%, before considering the source tolerance. High-impedance sensors or amplifier inputs require a lower-resistance switch alternative, such as the 35 Ω maximum DG413DY-E3, when their accuracy budget cannot tolerate that attenuation.
Route each switched node symmetrically and keep the four control inputs away from sensitive analog traces. Place the device close to the source or destination that dominates the switching-node capacitance. Maintain a continuous ground reference under the SOIC and return control-current paths directly to the system ground. These measures reduce switching transients coupled into the selected measurement channel.
Do not treat the listed 4.5 V to 30 V signal range as the complete operating specification. Confirm supply voltage, control thresholds, allowable analog input voltage, off-state leakage, switching time, and absolute maximum ratings in the DG413 Data Sheet (Rev. 7). Also verify the logic state for every switch position; the DG413 product page identifies 1:1 SPST routing, but pin-specific control mapping must come from the datasheet pin description.
