Product details
Overview
DG401DJ+ from Maxim Integrated is a dual, high-speed, single-pole/single-throw (SPST) analog switch optimized for precision signal routing in bipolar or single-supply systems. It features 20Ω typical on-resistance, 2Ω maximum on-resistance matching between channels, 15pC maximum charge injection, and operates from ±4.5V to ±20V or +10V to +30V supplies - enabling rail-to-rail analog signal handling in test equipment and military radios.
For engineers reviewing the DG401DJ+ datasheet, DG401DJ+ pinout, DG401DJ+ application, or DG401DJ+ equivalent, this device is selected for low-leakage, low-distortion analog switching where channel matching, timing consistency (tON ≤ 150ns), and temperature-stable off-isolation (>72dB at 1MHz) are critical in sample-and-hold circuits and battery-operated guidance systems.
Technical Context
The DG401DJ+ uses a silicon-gate 44V process to achieve guaranteed on-resistance flatness of ≤3Ω over the full analog signal range (±15V), ensuring minimal gain error in precision instrumentation. Its TTL/CMOS-compatible logic inputs (VL = +5V) interface directly with microcontrollers while maintaining low power consumption (≤35µW).
Internal substrate connection to V+ enables robust operation across –55°C to +125°C, and its dual SPST architecture provides independent, non-latching control of two analog paths with break-before-make timing not applicable - unlike the DG403/DG405 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (rDS(ON)) | 20Ω typ / 30Ω max - ensures minimal voltage drop and signal attenuation in 50Ω–1kΩ impedance paths. |
| On-resistance match | ≤2Ω max - guarantees matched gain/attenuation between channels in differential or dual-path circuits. |
| Charge injection | ≤15pC - limits voltage glitch on sampled nodes, critical for <12-bit accuracy in sample-and-hold stages. |
| Off leakage (IS(OFF)/ID(OFF)) | <5nA at +85°C - preserves signal integrity in high-impedance sensor interfaces and battery-monitoring circuits. |
| Switching time (tON/tOFF) | 150ns / 100ns max - supports >5MHz multiplexing in communications and real-time test systems. |
| Analog signal range | ±15V (with ±15V supplies) - enables full rail-to-rail switching without clipping in industrial ±12V systems. |
| Supply range | ±4.5V to ±20V or +10V to +30V - allows flexible integration into legacy bipolar or modern single-rail power domains. |
Pinout & Package
DG401DJ+ is housed in a 20-pin LCC (Leadless Chip Carrier) package with side-brazed ceramic construction, rated for –55°C to +125°C operation and suitable for high-reliability military and aerospace applications. The package has no external leads; connections are made via soldered perimeter pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | D1 / Drain 1 | Analog output terminal for Switch 1; bidirectional, rail-to-rail capable. |
| 2, 10 | D2 / Drain 2 | Analog output terminal for Switch 2; electrically isolated from D1 when off. |
| 3, 6 | S1 / Source 1 | Analog input terminal for Switch 1; connects to D1 when IN1 = logic high. |
| 4, 5 | S2 / Source 2 | Analog input terminal for Switch 2; connects to D2 when IN2 = logic high. |
| 9, 16 | IN1 / Logic Input 1 | TTL/CMOS-compatible control for Switch 1; active-high, referenced to VL. |
| 12, 19 | IN2 / Logic Input 2 | TTL/CMOS-compatible control for Switch 2; independent of IN1, no interlock. |
| 11 | V+ | Positive supply input; also connected to substrate - must be powered first during sequencing. |
| 14 | V- | Negative supply input; clamps analog signals below V– via internal diodes. |
| 13 | GND | Logic ground reference; separate from analog signal return paths in mixed-signal layouts. |
| 15 | VL | Logic supply input; must be +5V for TTL compatibility; ties to V+ for CMOS-level operation. |
| 2, 7, 17, 18, 20 | N.C. | Not internally connected - left unconnected per design; no pull-up/down required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V– to V+ without distortion - eliminates level-shifting in ±15V op-amp signal chains. |
| Guaranteed rFLAT(ON) ≤ 3Ω | Maintains consistent on-resistance across full signal swing - essential for low THD in audio routing and linear gain control. |
| Low charge injection (≤15pC) | Minimizes hold-step error in precision sample-and-hold amplifiers - enables sub-1LSB settling in 12-bit ADC front-ends. |
| Improved off leakage (<5nA @ +85°C) | Reduces drift in high-Z sensor multiplexers and battery-voltage monitoring circuits over extended temperature range. |
| Plug-in upgrade for legacy DG401 | Pin- and function-compatible with original DG401 - allows drop-in replacement without layout change in existing designs. |
Applications
| Sample-and-Hold Circuits | Test Equipment |
|---|---|
Use Scenario: Multiplexing multiple sensor outputs into a single high-precision ADC sampling stage. IC Role / Device Role / Timing Role: Dual SPST switch controlling analog path selection with simultaneous hold capacitor isolation.

Use Scenario: Signal path reconfiguration in automated test equipment (ATE) for RF and analog stimulus/response measurement. IC Role / Device Role / Timing Role: High-speed analog routing element enabling <150ns channel switching during test sequence execution. Use Value: 72dB off-isolation at 1MHz suppresses crosstalk between stimulus and measurement paths, improving dynamic range by >12dB. |
| Military Radios | Battery-Operated Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Lower on-resistance (15Ω typ), but only rated for –40°C to +85°C and single-supply only (+2.7V to +12V). | Suitable for commercial portable instruments; not qualified for military temp range or bipolar rails. | Select MAX4617ESE+ only if operating within 0°C–85°C and using single +5V/+12V supply - avoids need for VL bias network. |
| ADG1419BRUZ | Higher performance: 1.5Ω on-resistance match, 30pC charge injection, but requires ≥±5V supplies and consumes 120µW. | Better for ultra-low-distortion audio or high-speed data acquisition where matching and speed outweigh power/leakage trade-offs. | Choose ADG1419BRUZ when sub-1Ω channel match and <100ns tON are mandatory - accept higher leakage and power penalty. |
Compared with MAX4617ESE+ and ADG1419BRUZ, DG401DJ+ uniquely balances military-grade temperature range (–55°C to +125°C), bipolar/single-supply flexibility, and ultra-low leakage (<5nA) - making it the only option qualified for long-life, high-reliability embedded systems requiring both precision and ruggedness.

FAQ
What is the operating temperature range of the DG401DJ+?
The DG401DJ+ is specified for operation from –55°C to +125°C, validated across the full range for parameters including on-resistance match (≤2Ω), off-leakage (<5nA at +85°C), and switching time (tON ≤ 150ns). This makes DG401DJ+ suitable for aerospace, defense, and downhole industrial applications where extended thermal stability is required.
Does DG401DJ+ require a separate logic supply voltage (VL)?
Yes - DG401DJ+ requires VL = +5V for TTL-compatible logic input thresholds (VINH ≥ +2.4V, VINL ≤ +0.8V). If VL is tied to V+, the device operates with CMOS-level inputs instead. The VL pin must be decoupled with a 0.1µF capacitor to GND, and DG401DJ+ will not function correctly without a valid VL connection.
Can DG401DJ+ be used with a single +12V supply?
Yes - DG401DJ+ supports single-supply operation from +10V to +30V. With V+ = +12V and V– = 0V (GND), the analog signal range extends from 0V to +12V. Rail-to-rail capability is preserved, and all key specs (on-resistance, leakage, charge injection) remain valid per the datasheet's single-supply test conditions.
Is DG401DJ+ pin-compatible with the original DG401 series?
Yes - DG401DJ+ is a plug-in upgrade for industry-standard DG401 devices. Its 20-pin LCC footprint, pin functions, and logic behavior match the original DG401 family. No PCB changes are required when replacing legacy DG401CJ, DG401AK, or DG401AZ with DG401DJ+, provided the same supply and temperature requirements apply.
What is the maximum allowable voltage difference between V+ and V– for DG401DJ+?
The absolute maximum voltage difference between V+ and V– is +44V, as specified in the Absolute Maximum Ratings table. Exceeding this risks permanent damage. For reliable operation, DG401DJ+ should be used within the recommended supply ranges: ±4.5V to ±20V (bipolar) or +10V to +30V (single), ensuring V+ – V– ≤ 40V in practice.
