Product details
Overview
DG412DY+T from Maxim Integrated is a quad, normally open (NO), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in bipolar or single-supply systems. It features 45Ω max on-resistance at ±15V, <5nA off-leakage at +85°C, 100ns max tOFF, rail-to-rail analog signal handling (±15.5V), and TTL/CMOS logic compatibility - enabling use in test equipment front-ends and battery-operated audio routing.
For engineers reviewing the DG412DY+T datasheet, DG412DY+T pinout, DG412DY+T application, or DG412DY+T equivalent, key selection criteria include guaranteed on-resistance flatness (Δ4Ω), low charge injection (10pC max), ESD tolerance (2000V min), and operation across ±4.5V to ±20V or +10V to +30V supplies.
Technical Context
The DG412DY+T implements four independent SPST switches with NO configuration, controlled by separate digital inputs (IN1–IN4). Each switch conducts bidirectionally with matched on-resistance (≤3Ω difference between channels) and flat on-resistance over its full analog range (−15V to +15.5V with ±15V supplies).
It uses a 44V silicon-gate process to support high-voltage operation and low leakage. Logic interface operates at VL = 5V (TTL-compatible) or VL = V+, with input thresholds fixed at VINH = 2.4V and VINL = 0.8V - ensuring robust noise immunity without external level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally open (NO) - all four switches are open when logic input is low |
| RDS(ON) Max | 45Ω at ±15V - ensures minimal signal attenuation in precision DC/low-frequency paths |
| RFLAT(ON) | Δ4Ω max over full analog range - maintains consistent gain and linearity across signal swing |
| tOFF Max | 100ns - supports fast channel switching in automated test equipment and multiplexed data acquisition |
| Off-Leakage @ +85°C | <5nA - preserves accuracy in high-impedance sample-and-hold and sensor interfaces |
| Charge Injection | 10pC max - limits voltage glitch on sampled nodes, critical for 12-bit+ ADC front-ends |
| ESD Rating | 2000V min per Method 3015.7 - enables handling in standard lab environments without special precautions |
Pinout & Package
DG412DY+T is supplied in a 16-pin narrow SOIC package (package code S16-1), 7.5mm × 10.3mm body, 1.27mm pitch, with gull-wing leads and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Active-high logic; each independently enables its corresponding NO switch |
| S1–S4 | Analog source terminals | Low-impedance connection points for signal sources; bidirectional conduction path |
| D1–D4 | Analog drain terminals | Output-side analog nodes; symmetric RDS(ON) to S pins ensures no direction-dependent loss |
| V+ | Positive supply rail | Connects to substrate; supports up to +30V single-supply or +20V in bipolar mode |
| V− | Negative supply rail | Supports down to −20V; internal clamping diodes protect against overvoltage transients |
| GND | Ground reference | Logic ground return; separate from analog signal ground to minimize coupling |
| VL | Logic supply voltage | Must be 5V for TTL compatibility; tied to V+ for CMOS-level inputs |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG412BRZ | 44Ω RDS(ON) max at ±15V; 150ns tOFF; 10nA off-leakage @ +85°C | Higher switching time and leakage limit use in high-speed or ultra-low-power designs | Preferred where ADI ecosystem integration or RoHS-compliant lead-free finish is required |
| TS5A23157DGSR | 0.9Ω RDS(ON) at +3.3V; 50ns tON/tOFF; only supports single 1.65V–5.5V supply | Not suitable for ±15V or high-voltage signal routing; optimized for low-voltage portable gear | Select when operating from 3.3V logic and analog rails with strict on-resistance budgets |
Compared with ADG412BRZ and TS5A23157DGSR, the DG412DY+T delivers superior high-voltage capability (±20V), lower leakage at temperature, and proven ruggedness for industrial/military use - but requires higher supply voltages and exhibits slower switching than modern low-voltage alternatives.

FAQ
What is the maximum analog signal voltage range supported by the DG412DY+T?
The DG412DY+T supports an analog signal range of ±15.5V when operated with ±15V supplies, and up to +12V with a +12V single supply (V− = 0V). This rail-to-rail capability allows it to pass full-scale signals from industrial sensors and DACs without clipping or distortion - a key requirement confirmed in the Electrical Characteristics table under VANALOG parameter.
Does the DG412DY+T require a separate logic supply voltage (VL)?
Yes, the DG412DY+T requires VL to be externally supplied - typically at +5V for TTL compatibility or tied to V+ for CMOS-level inputs. The VL pin powers the digital interface circuitry and must remain within (GND − 0.3V) to (V+ + 0.3V); incorrect VL configuration will cause logic misoperation or damage, as specified in Absolute Maximum Ratings.
Can the DG412DY+T be used in a single-supply configuration with V− grounded?
Yes, the DG412DY+T supports single-supply operation with V− connected to GND and V+ set between +10V and +30V. In this mode, the analog signal range becomes 0V to V+ − 0.5V (e.g., 0V to +11.5V at V+ = +12V), and RDS(ON) increases slightly versus bipolar operation - verified in the Single Supply Electrical Characteristics table.
What is the thermal performance of the DG412DY+T in the narrow SOIC package?
In the 16-pin narrow SOIC (DG412DY+T), the DG412DY+T has a thermal resistance θJA of 8.70°C/W, allowing 696mW continuous power dissipation at +70°C ambient. Derating is linear above that temperature, supporting reliable operation in enclosed industrial enclosures without forced airflow - per the Absolute Maximum Ratings table.
How does the DG412DY+T handle electrostatic discharge during board assembly?
The DG412DY+T is rated for ≥2000V HBM ESD per Method 3015.7, making it suitable for standard handling in non-classified environments. However, input pins (IN1–IN4, VL) remain sensitive - best practice is to ground wrist straps and use conductive foam during manual placement, as confirmed in the New Features section and Absolute Maximum Ratings notes.
