Product details
Overview
ADG719SRJZ-EP-RL7 from Analog Devices is a monolithic CMOS SPDT analog switch in a 6-lead SOT-23 package, operating from 1.8 V to 5.5 V single supply, with 2.5 Ω typical on resistance, 200 MHz −3 dB bandwidth, and break-before-make switching action. It serves as a low-leakage, high-speed signal path selector in precision instrumentation and military-grade data acquisition systems.
For engineers reviewing the ADG719SRJZ-EP-RL7 datasheet, ADG719SRJZ-EP-RL7 pinout, ADG719SRJZ-EP-RL7 application, or ADG719SRJZ-EP-RL7 equivalent, key selection criteria include on-resistance flatness (0.75 Ω typ), rail-to-rail analog range (0 V to VDD), −55°C to +125°C operation, and TTL/CMOS-compatible digital control.
Technical Context
The ADG719SRJZ-EP-RL7 implements a single-pole double-throw (SPDT) topology with symmetrical bidirectional conduction and guaranteed break-before-make timing (8 ns typ). Its submicron CMOS process enables low charge injection (≤4 pC) and ultra-low leakage (±0.01 nA typ off-state).
It supports dual-voltage operation: at VDD = 5 V, tON is 12 ns max and off isolation reaches −67 dB at 10 MHz; at VDD = 3 V, RON rises to 6 Ω typ but retains full −55°C to +125°C functionality and 200 MHz bandwidth.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance (RON) | 2.5 Ω typ at VDD = 5 V - ensures minimal signal attenuation in precision analog paths |
| −3 dB Bandwidth | 200 MHz typ - supports video, high-speed DAC/ADC interface, and broadband signal routing |
| Switching Times | tON = 12 ns max, tOFF = 6 ns max - enables fast multiplexing in time-critical sampling systems |
| Off-Leakage Current | ±0.25 nA max at −55°C to +125°C - preserves accuracy in high-impedance sensor front-ends |
| Operating Temperature | −55°C to +125°C - qualified for aerospace, defense, and extended industrial environments |
| Supply Voltage Range | 1.8 V to 5.5 V single supply - compatible with Li-ion battery rails and mixed-voltage SoC interfaces |
| Charge Injection | ≤4 pC - minimizes voltage glitch in sample-and-hold and switched-capacitor circuits |
Pinout & Package
ADG719SRJZ-EP-RL7 is housed in a JEDEC-compliant 6-lead SOT-23 (RJ-6) package with gull-wing leads, 1.9 mm × 2.9 mm footprint, and 1.3 mm height. Thermal impedance θJA = 186.45°C/W on a 4-layer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Digital Control Input | TTL/CMOS-compatible logic pin selecting S1 (IN = 0) or S2 (IN = 1); no external pull-up required |
| 2 VDD | Positive Supply Rail | Single 1.8 V–5.5 V power source; powers internal logic and analog channel; decoupling recommended |
| 3 GND | Ground Reference | 0 V return for both digital control and analog signal paths; must be low-impedance |
| 4 S1 | Analog Source 1 | Bidirectional terminal; connects to D when IN = 0; supports rail-to-rail signals 0 V to VDD |
| 5 D | Common Drain | Shared analog I/O node; output of selected channel; low capacitance (27 pF typ on) |
| 6 S2 | Analog Source 2 | Bidirectional terminal; connects to D when IN = 1; matched RON and flatness vs. S1 |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Supports input/output signals from 0 V to VDD without clipping-critical for full-scale ADC/DAC interfacing |
| Break-before-make switching | Guaranteed 1 ns min tD prevents momentary short between S1 and S2-essential for fault-tolerant signal routing |
| Ultra-low power consumption | IDD ≤ 1.0 μA max across temperature-enables always-on monitoring in battery-constrained platforms |
| Military-grade qualification | AQEC-compliant with controlled baseline, single fab/test site, and enhanced change notification-meets MIL-PRF-38535 Class K requirements |
| Low crosstalk & high off-isolation | −62 dB crosstalk and −67 dB off-isolation at 10 MHz-preserves signal integrity in multi-channel RF/data acquisition |
Applications
| Audio Signal Routing | Sample-and-Hold Systems |
|---|---|
|
Use Scenario: Selecting between multiple microphone or line-level inputs in ruggedized field recorders or avionics comms units. IC Role / Device Role / Timing Role: SPDT analog switch providing low-noise, low-distortion signal path selection under −55°C to +125°C conditions. Use Value: 2.5 Ω RON and 0.75 Ω flatness minimize level mismatch and THD; 200 MHz bandwidth preserves audio fidelity up to 100 kHz. |
Use Scenario: Sampling analog sensor outputs (e.g., strain gauges, thermocouples) in flight control computers with strict timing jitter limits. IC Role / Device Role / Timing Role: Precision hold capacitor charging switch with <12 ns tON and ≤4 pC charge injection. Use Value: Low charge injection prevents hold-step error; rail-to-rail operation accommodates full sensor dynamic range. |
| Video Switching | Mechanical Reed Relay Replacement |
|
Use Scenario: Routing composite or component video signals in broadcast equipment deployed in uncontrolled environmental enclosures. IC Role / Device Role / Timing Role: High-bandwidth analog multiplexer enabling seamless video source switching without ghosting or delay. Use Value: 200 MHz −3 dB bandwidth supports NTSC/PAL and SDI baseband; −67 dB off-isolation suppresses inter-channel bleed. |
Use Scenario: Replacing electromechanical relays in automated test equipment (ATE) fixture boards requiring >10M cycle life and shock immunity. IC Role / Device Role / Timing Role: Solid-state SPDT switch delivering zero bounce, nanosecond settling, and no contact wear. Use Value: 100 mA peak current rating and 30 mA continuous support relay-like loads; −55°C to +125°C rating exceeds most reed specs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG719BRMZ-REEL | Commercial grade (−40°C to +85°C); same RON, bandwidth, and pinout; RoHS-compliant MSOP-8 package | Lacks military temp range and AQEC qualification; unsuitable for space/aerospace deployments | Select when cost-sensitive commercial designs require identical electrical performance without extended temperature or reliability assurance |
| MAX4617EUT+T | 2.7 V–5.5 V supply; 3.5 Ω RON typ; 150 MHz bandwidth; SOT-23-6; no extended temperature rating | Lower bandwidth and higher RON limit use in high-fidelity audio or fast-sampling systems | Choose for legacy designs already using Maxim switch footprints where moderate performance suffices and military spec is not required |
Compared with ADG719SRJZ-EP-RL7, the ADG719BRMZ-REEL offers identical analog performance but lacks −55°C capability and AQEC traceability, while the MAX4617EUT+T trades bandwidth and on-resistance for broader distributor availability-neither qualifies as drop-in for defense programs requiring EP-grade validation.

FAQ
What is the maximum supply voltage rating for ADG719SRJZ-EP-RL7?
The ADG719SRJZ-EP-RL7 has an absolute maximum VDD rating of +7 V, but its specified operational range is 1.8 V to 5.5 V. Exceeding 5.5 V may cause parametric shift or reliability degradation, even if within absolute max limits. Always operate ADG719SRJZ-EP-RL7 within the 1.8 V–5.5 V range for guaranteed performance across −55°C to +125°C.
Does ADG719SRJZ-EP-RL7 support bidirectional analog signal flow?
Yes, ADG719SRJZ-EP-RL7 supports fully bidirectional analog conduction: both S1 and S2 terminals function identically as inputs or outputs depending on signal direction and bias. This enables flexible use in transceiver interfaces, feedback loops, and shared-bus architectures without polarity constraints on ADG719SRJZ-EP-RL7's signal paths.
Is ADG719SRJZ-EP-RL7 pin-compatible with standard ADG719 variants?
Yes, ADG719SRJZ-EP-RL7 shares identical 6-lead SOT-23 (RJ-6) pinout and electrical behavior with non-EP versions like ADG719BRMZ, including IN, VDD, GND, S1, D, and S2 assignments. However, ADG719SRJZ-EP-RL7 adds AQEC compliance, extended temperature screening, and controlled manufacturing baseline-not reflected in pin compatibility alone.
What is the typical charge injection value for ADG719SRJZ-EP-RL7?
The ADG719SRJZ-EP-RL7 exhibits ≤4 pC typical charge injection at VDD = 5 V, as measured across source voltage (VS) sweep. This low value directly reduces voltage step errors in sample-and-hold and switched-capacitor circuits-making ADG719SRJZ-EP-RL7 suitable for 16-bit+ precision data acquisition where hold-mode accuracy is critical.
Can ADG719SRJZ-EP-RL7 be used with 1.8 V logic control signals?
Yes, ADG719SRJZ-EP-RL7 accepts 1.8 V logic-high inputs when VDD ≥ 2.4 V (VINH min = 2.4 V at VDD = 5 V; VINH min = 2.0 V at VDD = 3 V). For true 1.8 V–compatible control, operate ADG719SRJZ-EP-RL7 at VDD = 3.3 V or higher, ensuring the 1.8 V signal exceeds VINH threshold-verified in ADG719SRJZ-EP-RL7's truth table and input specification tables.
