Product details
Overview
DG417CJ+ from Maxim Integrated is a precision, normally closed (NC), single-pole/single-throw (SPST) analog switch IC designed for high-fidelity signal routing in rail-to-rail, bipolar or single-supply systems. It features guaranteed 35Ω max on-resistance, <5nA off-leakage at +85°C, and 10pC max charge injection - enabling low-distortion sample-and-hold and audio switching in battery-operated and test equipment.
For engineers reviewing the DG417CJ+ datasheet, DG417CJ+ pinout, DG417CJ+ application, or DG417CJ+ equivalent, key selection criteria include its NC configuration, ±4.5V to ±20V / +10V to +30V supply flexibility, guaranteed RDS(ON) matching (3Ω max), low tON/tOFF (<175ns/<145ns), and 2000V ESD tolerance per Method 3015.7.
Technical Context
The DG417CJ+ uses a 44V silicon-gate CMOS process to achieve rail-to-rail analog signal handling and TTL/CMOS logic compatibility. Its internal architecture ensures symmetrical conduction in both directions, with guaranteed on-resistance flatness (4Ω max) over the full analog range under bipolar supplies.
It operates across 0°C to +70°C, requires no external components for basic function, and supports unbalanced supplies (e.g., +24V/–5V). Logic-level translation is enabled via dedicated VL pin, allowing direct interface with 3.3V or 5V controllers without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 35Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| tON/tOFF | <175ns / <145ns - enables fast multiplexing in high-speed data acquisition and communications |
| Charge Injection | 10pC max - reduces sampling error and pedestal distortion in sample-and-hold circuits |
| Off-Leakage Current | <5nA at +85°C - preserves accuracy in high-impedance sensor interfaces and long-hold applications |
| Supply Range | +10V to +30V (single) or ±4.5V to ±20V (bipolar) - supports wide dynamic range signal conditioning |
| ESD Tolerance | 2000V min (HBM, Method 3015.7) - enhances robustness in manufacturing and field environments |
| Analog Signal Range | Rail-to-rail - allows full utilization of supply voltage headroom without clipping |
Pinout & Package
Package: 8-pin plastic DIP (0.300" width), RoHS-compliant, JEDEC MS-001 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Analog Source (S) | Normally closed switch terminal - connects to load when IN = LOW |
| 2 | No Internal Connection (N.C.) | Unused pin - must be left floating or grounded per layout best practice |
| 3 | GND | Logic ground reference - separate from analog ground but tied at system star point |
| 4 | V+ | Analog positive supply - sets upper rail for analog signal range and powers internal circuitry |
| 5 | VL | Logic supply input - configurable for TTL (5V) or CMOS (V+) logic threshold compatibility |
| 6 | IN | Digital control input - active-low logic controls NC state; compatible with 3.3V/5V microcontrollers |
| 7 | V− | Analog negative supply - sets lower rail; connect to 0V for single-supply operation |
| 8 | D | Analog Drain (common) - bidirectional signal path shared with S; handles rail-to-rail voltages |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RDS(ON) match | 3Ω max between channels - critical for matched gain/attenuation in differential or dual-path systems |
| Rail-to-rail signal handling | Full V− to V+ analog swing - eliminates need for level-shifting in ±15V industrial or audio front-ends |
| Low power consumption | 35µW max - extends battery life in portable test instruments and remote sensors |
| TTL/CMOS logic compatibility | VL pin enables seamless interface with mixed-voltage digital controllers without external buffers |
| Improved off-isolation | 68dB at 1MHz - suppresses crosstalk in multi-channel multiplexers used in data loggers and PBX systems |
Applications
| Sample-and-Hold Circuits | Communications Systems |
|---|---|
|
Use Scenario: Precision acquisition of analog sensor outputs before ADC conversion in automated test equipment. IC Role / Device Role / Timing Role: Normally closed analog switch isolating hold capacitor during sampling phase; controlled by precise timing generator. Use Value: 10pC max charge injection minimizes pedestal error, while <5nA leakage maintains hold voltage stability over 100ms intervals. |
Use Scenario: Signal routing in modem line interface cards for analog/digital mode switching and echo cancellation paths. IC Role / Device Role / Timing Role: SPST analog switch selecting between transmit/receive paths under microcontroller GPIO control. Use Value: 35Ω RDS(ON) and 68dB off-isolation preserve signal integrity across voice-band (300Hz–3.4kHz) and V.34/V.90 modulation bands. |
| Battery-Operated Systems | Audio Signal Routing |
|
Use Scenario: Power-gating analog front-end stages in handheld multimeters and portable oscilloscopes to extend runtime. IC Role / Device Role / Timing Role: Low-leakage NC switch disconnecting bias networks and amplifiers during sleep mode.

IC Role / Device Role / Timing Role: Bidirectional analog switch routing line-level signals between inputs, effects loops, and outputs. Use Value: Rail-to-rail operation supports ±12V audio rails; low RDS(ON) flatness (4Ω max) ensures consistent frequency response across signal range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | SPDT, 1.5Ω RDS(ON), +3.3V/+5V logic only, no VL pin | Requires external level shifting for ±15V analog rails; better for low-voltage, high-speed digital systems | Select ADG1419BRUZ when ultra-low on-resistance and 3.3V logic interface are prioritized over bipolar supply flexibility. |
| TS5A23157DCUR | SPST NO, 0.9Ω RDS(ON), 5V-only supply, 1.65V–5.5V logic | Not rated for ±15V operation; unsuitable for rail-to-rail industrial or audio signal ranges | Choose TS5A23157DCUR only for low-voltage, cost-sensitive consumer audio routing where bipolar supplies are absent. |
Compared with DG417CJ+, ADG1419BRUZ offers lower on-resistance but lacks VL pin flexibility and bipolar supply support, while TS5A23157DCUR provides faster switching and lower RDS(ON) yet cannot handle ±15V analog signals - making DG417CJ+ uniquely suited for legacy industrial and military-grade analog signal conditioning.

FAQ
What is the operating temperature range for DG417CJ+?
The DG417CJ+ is specified for 0°C to +70°C ambient operation. This commercial-grade temperature range aligns with its plastic DIP packaging and targets applications such as benchtop test equipment, audio interfaces, and non-military industrial systems. The device's <5nA off-leakage at +85°C reflects margin beyond spec, but full parameter guarantees apply only within the 0°C to +70°C range. DG417CJ+ does not support extended or military temperature grades.
Is DG417CJ+ pin-compatible with older DG417 variants?
Yes, DG417CJ+ maintains identical 8-pin DIP pinout and electrical behavior with legacy DG417 devices, including DG417CJ and DG417DJ. It is a plug-in upgrade with improved RDS(ON) matching (3Ω max), lower charge injection (10pC max), and tighter off-leakage specs. No PCB or firmware changes are required when replacing earlier DG417 versions in existing designs.
Can DG417CJ+ operate from a single +12V supply?
Yes, DG417CJ+ supports single-supply operation from +10V to +30V. For +12V use, connect V− to 0V (ground), set VL to +5V for TTL compatibility, and ensure analog signals remain within 0V to +12V. On-resistance increases slightly versus ±15V operation (e.g., ~40Ω typ), but all key specs - including tON/tOFF, leakage, and charge injection - remain fully guaranteed.
What is the maximum analog signal voltage DG417CJ+ can switch?
DG417CJ+ supports rail-to-rail analog signals from V− to V+. With ±15V supplies, it switches ±15V signals; with +12V/V− = 0V, it handles 0V to +12V. Absolute maximum ratings allow V+ up to +44V and V− down to –44V, but functional analog range is strictly bounded by the applied supply rails. Exceeding V+ or V− risks diode clamping and increased leakage.
Does DG417CJ+ require external protection diodes for overvoltage?
DG417CJ+ includes internal ESD protection (2000V HBM), but external series diodes are recommended if supply sequencing cannot be controlled - especially during power-up/down. As shown in Maxim's Figure 1, two small-signal diodes (e.g., 1N4148) in series with V+ and V− limit transient overvoltage without degrading RDS(ON) or leakage. This adds ~1.4V headroom reduction but preserves signal integrity in uncontrolled power environments.
