Product details
Overview
DG412CUE+T from Maxim Integrated is a quad, normally open (NO), single-pole/single-throw (SPST) analog switch IC designed for bidirectional signal routing in precision analog systems. It features 35Ω max on-resistance, <5nA off-leakage at +85°C, 150ns max tON, ±4.5V to ±20V bipolar or +10V to +30V single-supply operation, and rail-to-rail signal handling - enabling use in battery-operated test equipment and audio signal routing.
For engineers reviewing the DG412CUE+T datasheet, DG412CUE+T pinout, DG412CUE+T application, or DG412CUE+T equivalent, key selection criteria include guaranteed on-resistance matching (≤3Ω), low charge injection (≤10pC), ESD tolerance (≥2000V), and TSSOP-16 package compatibility with space-constrained industrial and communications PCBs.
Technical Context
The DG412CUE+T implements four independent SPST switches with TTL/CMOS-compatible digital control inputs and a dedicated VL logic supply pin. Its silicon-gate 44V process enables robust operation across wide supply ranges while maintaining low RDS(ON) flatness (Δ4Ω max) over the full analog signal range (±15.5V).
Switching is fully bidirectional with symmetrical on-resistance and matched channel performance. Charge injection is minimized via internal architecture, ensuring minimal transient disturbance during sample-and-hold sampling - critical for high-fidelity data acquisition and guidance system interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 35Ω max at ±15V supplies - ensures minimal signal attenuation and gain error in precision analog paths. |
| On-Resistance Match | 3Ω max between channels - enables accurate channel-to-channel signal routing without calibration. |
| Off-Leakage Current | <5nA at +85°C - preserves DC accuracy in high-impedance sensor front-ends and battery-powered hold circuits. |
| Charge Injection | 10pC max - limits voltage glitch on sampled capacitors, supporting ≤12-bit effective resolution in S/H applications. |
| Switching Time (tON/tOFF) | 150ns / 100ns max - supports multiplexing of signals up to ~3MHz without significant settling delay. |
| Analog Signal Range | ±15.5V with ±16.5V supplies - accommodates industrial ±10V and military ±12V signal standards. |
| ESD Tolerance | 2000V min per Method 3015.7 - provides robust handling during board assembly and field service. |
Pinout & Package
Package: 16-pin TSSOP (U16-2), 4.4mm × 5.0mm body, 0.65mm pitch, exposed pad not present (non-QFN variant). RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| D1–D4 | Analog drain terminal | One side of each SPST switch; bidirectional, interchangeable with source for signal routing. |
| S1–S4 | Analog source terminal | Other side of each SPST switch; connects to load, ADC input, or downstream signal path. |
| V+ | Positive supply rail | Bias for internal circuitry and switch conduction; must be ≥ V− + 9V for stable operation. |
| V− | Negative supply rail | Reference for bipolar operation; tied to GND for single-supply mode (+10V to +30V). |
| GND | Analog ground reference | Return path for leakage currents and substrate bias; separate from digital ground recommended. |
| VL | Logic supply voltage | Defines logic threshold; connect to +5V for TTL compatibility or 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 |
|---|---|---|---|
| ADG412BRUZ | 44V abs max rating; 35Ω RDS(ON); 100ns tOFF; but only 1000V ESD rating and no guaranteed RFLAT(ON). | Lower ESD robustness limits suitability for field-deployable test gear; lacks flatness spec for precision S/H. | Select ADG412BRUZ only if cost sensitivity outweighs ESD and flatness requirements. |
| TS5A23157DCUR | Single-supply only (1.65V–5.5V); 0.9Ω RDS(ON); but ±1.25V max analog range and no bipolar support. | Cannot replace DG412CUE+T in ±15V industrial or military signal chains; limited to low-voltage consumer audio. | Use TS5A23157DCUR only in battery-powered 3.3V/5V systems where ultra-low RON is critical and bipolar operation is unnecessary. |
Compared with ADG412BRUZ and TS5A23157DCUR, DG412CUE+T uniquely delivers bipolar supply support, guaranteed on-resistance flatness, and 2000V ESD tolerance - making it the only viable option for ruggedized, wide-dynamic-range analog multiplexing in defense and industrial test platforms.

FAQ
What is the operating temperature range for DG412CUE+T?
The DG412CUE+T is rated for 0°C to +70°C ambient operation. This commercial-grade temperature range is validated per the device's ordering code "C" suffix and applies to all electrical specifications in the datasheet unless otherwise noted. The TSSOP-16 package supports reflow soldering per JEDEC J-STD-020, and thermal performance remains stable within this range without derating.
Can DG412CUE+T operate from a single +12V supply?
Yes, DG412CUE+T supports single-supply operation from +10V to +30V. When using +12V, connect V− to GND and set VL to +5V for TTL compatibility. Analog signal range becomes 0V to +12V, and RDS(ON) increases slightly versus ±15V operation - typical on-resistance is ~45Ω at +12V per Figure DG411-04 in the datasheet.
Is DG412CUE+T pin-compatible with older DG412 variants?
Yes, DG412CUE+T is a plug-in upgrade for industry-standard DG412 devices in TSSOP-16 packaging. Pinout, footprint, and logic behavior are identical to DG412CUE and DG412EUE. Key improvements - including lower off-leakage (<5nA at +85°C) and tighter RDS(ON) matching (≤3Ω) - require no PCB or firmware changes.
What is the maximum analog signal voltage DG412CUE+T can handle?
DG412CUE+T supports analog signals from V− to V+, with absolute maximum ratings of V+ ≤ 44V and V− ≥ −2V relative to GND. With ±15V supplies, the usable analog range is ±15.5V. Exceeding V+ or V− clamps signals via internal diodes - forward current must be limited to 30mA continuous or 100mA pulsed to avoid damage.
Does DG412CUE+T require external protection diodes for overvoltage?
No, DG412CUE+T does not require external protection diodes under normal operation. Internal clamp diodes provide inherent protection, but proper supply sequencing (V+ first, then VL, V−, and logic inputs) is mandatory. If sequencing cannot be guaranteed, two external series diodes per supply rail - as shown in Figure 1 of the datasheet - add robust overvoltage margin without degrading RDS(ON) or leakage.
