DG413DY-E3 Overview
A CMOS analog switch is a semiconductor device that routes or gates analog signals using MOSFET transmission gates controlled by TTL/CMOS-compatible logic inputs. Within the signal-chain hierarchy, analog switches sit between logic ICs and analog multiplexers, serving as building blocks for signal routing, sample-and-hold circuits, and channel selection in data acquisition systems.
Key features include ultra-low power dissipation of 0.35 uW, making the DG413DY-E3 suitable for battery-powered and portable instrumentation; a 44 V maximum supply rating with flexible dual-supply operation (V+ to V-); fast switching with typical turn-on time of 110 ns; and TTL/CMOS-compatible logic inputs. The switches conduct equally well in either direction, and the DG413 variant offers normally-open (NO) logic polarity for all four channels.
The device is built on a monolithic CMOS process that combines a high-voltage CMOS driver stage with low-threshold MOSFET switches, achieving low charge injection and glitch-free switching transitions. Compared with the older DG211/DG212 series it replaces, the DG411/DG412/DG413 family offers lower on-resistance and faster switching in the same footprint.
Typical applications include precision signal routing in data acquisition systems, audio signal switching, battery-powered test equipment, industrial control channel selection, and communication-system switch matrices, where low power and glitch-free performance are priorities.
When designing with the DG413DY-E3, keep the analog signal range within V+ and V- supply rails to avoid latch-up, and use short, low-capacitance traces on the source/drain lines to preserve switching speed and minimize crosstalk.

Typical Applications
DG413DY-E3 is suitable for 6 applications: Data Acquisition Signal Multiplexing, Audio Signal Routing, Battery-Powered Portable Instrumentation, Industrial Control Channel Selection, Communication System Switch Matrices, Sample-and-Hold and Precision Gating Circuits.
Data Acquisition Signal Multiplexing
The DG413DY-E3 is well suited for data acquisition front ends because its 110 ns turn-on time allows fast channel-to-channel settling while its 35 ohm on-resistance introduces predictable, low insertion loss ahead of an ADC or instrumentation amplifier. Four independently controlled SPST channels let a single SOIC-16 device gate four sensor or signal lines under TTL/CMOS control from a microcontroller or FPGA. Placed directly after signal conditioning and before the sampling stage, the switch's glitch-free transitions prevent false charge injection into sample-and-hold capacitors, and its 0.35 uW quiescent consumption adds negligible power budget in multi-channel systems.
Recommended
Audio Signal Routing
In audio path switching, the DG413DY-E3's glitch-free switching and bidirectional conduction minimize audible clicks and pops during source or route changes. The 15 V analog signal range with dual-supply capability (up to 44 V total window) accommodates professional line-level signals with headroom, while 35 ohm on-resistance creates only modest insertion loss when driving high-impedance loads such as op-amp summing stages. Its ultra-low 0.35 uW power keeps standby drain negligible in always-on consoles and mixers. Engineers should add a small RC bleed network or short-to-mute sequencing to further suppress transients during switch transitions in high-fidelity applications.
Recommended
Battery-Powered Portable Instrumentation
The defining parameter for portable designs is power, and the DG413DY-E3's 0.35 uW dissipation makes it a near-zero-burden routing element in battery-operated multimeters, portable environmental loggers, and handheld testers. TTL/CMOS-compatible logic inputs connect directly to microcontroller GPIO without level-shifting, and single-supply capability simplifies rail architecture in 5 V or single-battery systems. Because the switches conduct equally in either direction, one SOIC-16 device can serve both signal acquisition and stimulus routing. The -40C to +85C temperature range supports outdoor field equipment, and the SOIC-16 footprint keeps PCB area small for compact enclosures.
Recommended
Industrial Control Channel Selection
Industrial automation systems use the DG413DY-E3 to select among redundant sensor lines, gate actuator feedback signals, and switch mode-control references. The 44 V maximum supply rating and 15 V analog signal range provide robustness against industrial rail transients, while the CMOS switch's low power suits always-on monitoring nodes. Glitch-free switching ensures that PLC analog input modules do not register false transitions during channel swaps, and the wide -40C to +85C temperature range covers cabinet environments. Mount the switch close to the signal entry connector to limit exposed high-impedance nodes and add TVS clamping on field-wired lines for surge protection.
Recommended
Communication System Switch Matrices
The DG413DY-E3 builds compact switch matrices for baseband and IF signal routing in communication equipment, where its 110 ns switching time enables rapid reconfiguration between receive and test paths. The bidirectional 15 V signal handling accommodates both symmetric and unbalanced interfaces, and TTL/CMOS control allows direct addressing from system logic or an FPGA. In matrix configurations, multiple SOIC-16 devices cascade to form crosspoints; the 35 ohm series on-resistance per switch must be budgeted into the overall link loss calculation. The ultra-low 0.35 uW power consumption keeps idle crosspoints from burdening equipment standby power budgets.
Recommended
Sample-and-Hold and Precision Gating Circuits
The DG413DY-E3 functions as a precision gating element in sample-and-hold front ends, peak detectors, and integrator reset circuits. Its CMOS transmission-gate switch conducts equally well in either direction with low on-resistance (35 ohm typ), which shortens acquisition time constants when charging hold capacitors, while glitch-free switching behavior prevents charge-transfer errors during the open transition. The 15 V analog signal range supports precision op-amp output swings on +/-12 V rails. Designers should choose low-leakage (low-dielectric-absorption) hold capacitors such as polypropylene or C0G ceramics and guard the switch node on the PCB to minimize off-state leakage-induced droop.

Key Differentiators

- Identical footprint across three manufacturers (vs DG413DYZT)
- Glitch-free bidirectional switching (vs DG411DY-E3)
Design Notes
Keep analog signal traces (S/D pins) short and direct, and guard high-impedance switch nodes with ground rings to limit off-state leakage and crosstalk between adjacent channels. Place 0.1 uF ceramic decoupling capacitors between V+ and GND and between V- and GND as close to pins 1, 2, and 8 as possible. Route logic inputs away from analog lines to prevent coupling of control-signal transients into the switched signal during the 110 ns transition window.
Never allow the analog signal on any source or drain pin to exceed the supply rails (beyond V- or above V+); forward-biasing the internal CMOS protection structures can cause latch-up or permanent damage. Verify that the total supply window does not exceed the 44 V maximum rating, including transient overshoot on industrial rails. Also confirm the required logic polarity before layout: the DG413 channels are normally open, while DG411/DG412 family members differ, and substituting blindly reverses switch logic.
Budget the 35 ohm typical on-resistance into signal-chain gain and accuracy calculations, especially in low-impedance paths where it forms a divider with the load. In audio and precision applications, mitigate switching clicks by sequencing control edges slowly (RC on logic inputs) or momentarily grounding the switched node before transitions. For fastest settling in multiplexed ADC front ends, minimize source impedance driving the switch so the RC settling time constant stays well below the 110 ns class switching interval.
