Product details
Overview
DG412CUE+ 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 35Ω max on-resistance, <5nA off-leakage at +85°C, 10pC max charge injection, and operates from ±4.5V to ±20V or +10V to +30V supplies - enabling use in battery-operated test equipment and military radios.
For engineers reviewing the DG412CUE+ datasheet, DG412CUE+ pinout, DG412CUE+ application, or DG412CUE+ equivalent, key selection criteria include guaranteed RDS(ON) matching (≤3Ω), rail-to-rail analog signal handling (±15.5V), TTL/CMOS logic compatibility, and low dynamic power consumption (35µW max).
Technical Context
The DG412CUE+ implements four independent SPST switches with NO configuration, controlled by active-low logic inputs referenced to VL. Its silicon-gate 44V process enables robust operation across wide supply ranges while maintaining tight on-resistance flatness (Δ4Ω max) over the full analog signal range.
Switching is bidirectional with symmetrical conduction, supported by low capacitance (9pF off-capacitance per channel) and high off-isolation (68dB at 1MHz). Charge injection (≤10pC) and off-leakage (<5nA at +85°C) are specified and tested per Method 3015.7 ESD standard (2000V min).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally open (NO) configuration - all four channels open when logic input is low |
| RDS(ON) Max | 45Ω at ±15V supplies - ensures minimal signal attenuation in precision analog paths |
| RDS(ON) Match | ≤3Ω max between channels - critical for matched gain/phase in multi-channel signal routing |
| Charge Injection | ≤10pC - limits voltage glitch on sampled nodes in sample-and-hold circuits |
| Off-Leakage Current | <5nA at +85°C - preserves DC accuracy in high-impedance sensor interfaces |
| Analog Signal Range | ±15.5V with ±16.5V supplies - supports rail-to-rail operation without clipping |
| Logic Compatibility | TTL/CMOS with VL = 5V - allows direct interfacing to microcontrollers and FPGAs |
Pinout & Package
Package: 16-pin TSSOP (U16-2), 4.4mm × 5.0mm body, 0.65mm pitch, exposed pad connected to V+ per datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 2, 15, 16) | Logic Control Inputs | Active-low enables; low = switch closed (NO), high = open; referenced to VL |
| D1–D4 (Pins 3, 4, 13, 14) | Analog Drain Terminals | High-impedance side of switch; connects to load or downstream circuitry |
| S1–S4 (Pins 5, 6, 11, 12) | Analog Source Terminals | Low-impedance side; typically tied to signal source or common reference |
| V+ (Pin 13) | Positive Supply | Connects to substrate; must be ≥ |V−| + 1V for proper biasing |
| V− (Pin 4) | Negative Supply | Required for bipolar operation; sets lower rail of analog signal range |
| GND (Pin 5) | Ground Reference | Logic ground return; separate from analog signal ground in mixed-signal layouts |
| VL (Pin 10) | Logic Supply Voltage | Set to 5V for TTL compatibility or to V+ for CMOS-level inputs |
Key Features

| ESD tolerance | 2000V minimum per Method 3015.7 - enhances reliability in handling and assembly |
Applications
| Sample-and-Hold Circuits | Communication Systems |
|---|---|
Use Scenario: Capturing precise analog waveforms in data acquisition front-ends with minimal hold-mode error. IC Role / Device Role / Timing Role: DG412CUE+ acts as the acquisition-phase switch, connecting the input signal to the hold capacitor with low charge injection.

Use Scenario: Routing audio or baseband signals between RF transceivers and codec interfaces in PBX/PABX infrastructure. IC Role / Device Role / Timing Role: DG412CUE+ serves as a low-distortion analog multiplexer, selecting between multiple line inputs under microcontroller control. Use Value: 45Ω RDS(ON) and 9pF off-capacitance minimize insertion loss and crosstalk (<−68dB), maintaining voice SNR >70dB. |
| Test Equipment | Military Radios |
Use Scenario: Configuring signal paths in automated test systems where channel isolation and repeatability are critical. IC Role / Device Role / Timing Role: DG412CUE+ functions as a reconfigurable patch panel element, switching calibration references or DUT connections.

Use Scenario: Managing antenna diversity and band selection in ruggedized HF/VHF tactical radios operating across −40°C to +85°C. IC Role / Device Role / Timing Role: DG412CUE+ routes receive/transmit paths between filters, amplifiers, and antennas under harsh environmental conditions. Use Value: <5nA off-leakage at +85°C prevents signal degradation in high-Z RF detector stages, sustaining sensitivity over full military temperature range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Lower RDS(ON) (1.8Ω typ), but requires ±15V only; no single-supply support | Better for low-voltage precision instrumentation; unsuitable for +24V-only systems | Select if ultra-low on-resistance is prioritized and supply architecture permits dual rails |
| TS5A3157DCUR | Single-supply only (+1.65V to +5.5V); 10Ω RDS(ON); smaller 6-pin SC70 package | Targeted at low-voltage portable electronics; lacks bipolar capability and high-voltage swing | Choose for space-constrained, battery-powered consumer devices - not for industrial/military voltage ranges |
Compared with ADG1412BRUZ and TS5A3157DCUR, the DG412CUE+ uniquely supports both wide-range bipolar (±4.5V to ±20V) and high-voltage single-supply (up to +30V) operation while delivering verified leakage and matching performance across its full rated temperature range.

FAQ
What is the maximum analog signal voltage range supported by the DG412CUE+?
The DG412CUE+ supports an analog signal range of ±15.5V when operated with ±16.5V supplies, and up to 0V to +12V with a +12V single supply. This rail-to-rail capability ensures full-swing signal handling without clipping, making DG412CUE+ suitable for high-dynamic-range applications like test instrumentation and military comms.
Is the DG412CUE+ pin-compatible with the original DG412 series?
Yes, the DG412CUE+ is a plug-in upgrade for industry-standard DG412 devices, retaining identical 16-pin TSSOP pinout, logic behavior, and functional diagram. No PCB changes are required when replacing legacy DG412CUE or DG412CJ variants with DG412CUE+, as confirmed by Maxim's ordering information and pin configuration diagrams.
What logic voltage levels does the DG412CUE+ accept on its IN pins?
The DG412CUE+ accepts TTL/CMOS-compatible logic inputs when VL is set to 5V (VINH ≥ 2.4V, VINL ≤ 0.8V). If VL is tied to V+, it supports CMOS-level thresholds relative to the positive supply. Input current remains below ±0.5µA across temperature, ensuring low loading on driving logic - a key feature of the DG412CUE+ design.
How does the DG412CUE+ perform at elevated temperatures?
The DG412CUE+ guarantees off-leakage current <5nA at +85°C and maintains RDS(ON) flatness (Δ4Ω max) over the full analog signal range. On-resistance increases predictably with temperature (see Figure DG411-02), but the device remains fully functional and parametrically compliant across its 0°C to +70°C commercial grade rating - a core specification of the DG412CUE+.
Can the DG412CUE+ operate from unbalanced supplies such as +24V and −5V?
Yes, the DG412CUE+ supports unbalanced supplies - including +24V/−5V - as explicitly stated in the Applications Information section. The absolute maximum rating requires V+ − V− ≤ 44V, and analog signal range scales accordingly. This flexibility makes DG412CUE+ adaptable to nonstandard power architectures found in legacy industrial and military platforms.
