DG413 Overview
An analog switch is a semiconductor device that routes or blocks analog signal paths under digital control. Within the signal-routing hierarchy, the analog switch sits below analog multiplexers and above discrete transistor switches, forming a core building block of signal conditioning and power management systems. The DG411/DG412/DG413 family from Analog Devices (originally Maxim Integrated, also second-sourced by Renesas/Intersil and Vishay Siliconix) is an industry-standard pinout.
Key features include TTL- and CMOS-compatible digital inputs, operation from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies, and a 44V silicon-gate process with an epitaxial layer that prevents the latch-up associated with older CMOS technologies. The improved family offers lower on-resistance (35 ohm vs. older DG211/DG212 parts) and faster switching (tON 175 ns class, max 150 ns; tOFF max 100 ns per Analog Devices).
Technically, the DG413 uses a high-voltage silicon-gate CMOS process enabling 40VP-P signal handling and reduced charge injection versus predecessors. It is a drop-in replacement for the popular DG211/DG212 series.
Typical applications include audio signal routing, sample-and-hold circuits, precision test instrumentation, and industrial signal multiplexing, where low on-resistance and fast switching improve signal fidelity.
Design tip: keep the analog signal within the supply rails and decouple V+ and V- pins with 0.1 uF ceramics to preserve charge-injection performance.

Typical Applications
DG413 is suitable for 6 applications: Audio Signal Routing, Sample-and-Hold Circuits, Instrumentation Signal Multiplexing, Industrial Control Signal Steering, Battery-Powered Portable Instrumentation, Communication and Test Equipment Switching.
Audio Signal Routing
The DG413 is explicitly listed by Analog Devices for audio signal routing. Its 35 ohm on-resistance introduces only modest insertion loss into low-impedance line-level paths, and the 100 ns max tOFF keeps switching clicks short relative to audio timescales. Powered from ±15V rails, the switch passes AC audio signals around ground without coupling concerns. Place the switch after input coupling capacitors and drive the IN pins from a muted-microcontroller GPIO; unlike relays, it consumes virtually no power and offers millions of switching cycles, making it ideal for preamp source selection and effect-pedal true-bypass style signal steering.
Recommended
Sample-and-Hold Circuits
In sample-and-hold front ends for data converters, the DG413's 150 ns max acquisition switching time and low charge injection (improved over DG211/DG212 per Renesas) minimize pedestal error on the hold capacitor. Using the NC switches of the DG413 means the hold capacitor defaults to a defined state if supply power is lost - a fail-safe property unavailable with all-NO devices such as the DG411. Operate with ±15V supplies so the analog signal stays well inside the rails, buffer the switch output with a FET-input op amp to avoid droop, and keep hold capacitance in the 1 nF to 10 nF range for an acquisition/droop balance.
Recommended
Instrumentation Signal Multiplexing
Test and measurement front ends use DG413 switches to select among multiple sensor or probe inputs. The 44V silicon-gate process with epi-layer latch-up immunity tolerates the overrange events common on bench instruments, and TTL/CMOS-compatible IN pins connect directly to the control logic. At 35 ohm max on-resistance, channel-to-channel gain mismatch is small and calibratable in firmware. Because off-leakage and crosstalk are low, high-impedance (100 kohm and above) source networks can be multiplexed without significant error; add a unity-gain buffer per channel to make settling deterministic after each 150 ns transition.
Recommended
Industrial Control Signal Steering
Factory systems use the DG413 to gate analog control signals - 0-10V setpoints, 4-20mA-derived voltages, and sensor lines - under logic control. The single +10V to +30V supply range matches industrial 24V rails directly without a separate dual supply, and the 15V analog signal range covers standard industrial signal levels. Latch-up immunity from the epitaxial silicon-gate process handles the noisy electrical environment of motor drives and relays nearby. Use the NC switch pair for shutdown-safe default routing, add TVS diodes on field-side nodes, and decouple V+ with 0.1 uF plus 10 uF at the switch pins.
Recommended
Battery-Powered Portable Instrumentation
With CMOS quiescent power around the 0.35 mW class, the DG413 suits battery-operated dataloggers and handheld meters where switch array power must be negligible versus the display and MCU budget. Running from a single 12V battery rail (the voltage at which the family is characterized per Renesas), the switch passes battery-referenced signals without dual supplies. The 35 ohm on-resistance adds minimal burden to millivolt-level measurement bridges when the buffer input impedance is 1 Mohm or higher. Power down whole signal sections by holding IN pins low, and prefer the NC channels for signals that must remain connected in sleep mode.
Recommended
Communication and Test Equipment Switching
Bench instruments, ATE matrices, and communication line cards use DG413 switches to connect or disconnect test points, calibration sources, and signal loops. The 44V supply rating and 40VP-P signal capability accommodate wide-dynamic-range video and telecom signals, while 100 ns tOFF supports fast disconnect timing in automated test sequences. Break-before-make behavior is inherent since each SPST switch is independent, letting the designer sequence multiple DG413 units in software to build larger matrices with guaranteed timing margins. Keep PCB traces short and ground-guarded to preserve off-isolation at high frequency.

Design Notes
The DG413 accepts +10V to +30V single-supply or ±4.5V to ±20V bipolar operation from a 44V-rated silicon-gate process. For audio or AC-coupled signals, prefer ±15V split rails so the analog signal swings around ground and never approaches the rail limits; for industrial 24V systems, single-supply operation directly off the rail is valid but limits the analog signal range to voltages within 0V to V+. Decouple both supply pins with 0.1 uF ceramics placed within 5 mm of the pins.
The 35 ohm on-resistance forms an RC with the source impedance and load capacitance; with a 10 kohm source the insertion loss is about 0.35%, but with a 100 ohm source the 35 ohm switch resistance causes roughly 26% attenuation. Drive the switch from a low-impedance buffer and load it with a high-impedance stage. Charge injection is reduced versus DG211/DG212 but still produces a small pedestal on sample-and-hold nodes - calibrate it out or increase hold capacitance.
Do not let the analog input exceed the supply rails; although the epi-layer process prevents destructive latch-up, signals outside the rails forward-bias internal protection structures and corrupt the signal. Note the DG413 mixes normally-closed and normally-open switches - verify which pair (pins 9-10 and 11-12 are NO, pins 13-14 and 15-16 are NC per configuration) carries your default-connected path before layout. Consult the Analog Devices DG411/DG412/DG413 datasheet truth table during schematic review.
Keep analog source/drain traces short and away from the IN control lines to limit capacitive feedthrough during the 100-150 ns transitions. Place a ground guard ring around high-impedance off-state nodes to preserve off-isolation. The 16-pin SOIC has no exposed pad, so thermal management is trivial, but a solid ground plane under the part reduces crosstalk between the four independent switches in dense multiplexer arrays.
