Product details
Overview
DG441DVZ from Intersil is a monolithic quad SPST CMOS analog switch with TTL/CMOS-compatible digital inputs, 85Ω max ON resistance, 250ns max tON, and ±20V analog signal range. It operates from single (5–34V) or split (±5V to ±22V) supplies and serves as a drop-in upgrade for DG201A/DG202 in precision sample-and-hold and audio routing circuits.
For engineers reviewing the DG441DVZ datasheet, DG441DVZ pinout, DG441DVZ application, or DG441DVZ equivalent, this device supports high-reliability data acquisition, battery-powered instrumentation, and bidirectional analog signal switching where low charge injection (<1pC), fast settling, and rail-to-rail analog handling are critical.
Technical Context
The DG441DVZ implements four independent bilateral SPST switches using a high-voltage silicon-gate CMOS process with epitaxial latch-up protection. Its logic threshold reference enables stable operation across wide supply ranges (44V max differential).
Each switch exhibits matched ON resistance over ±5V analog input range and supports symmetrical, asymmetrical, or single-ended supply configurations - with V+ ≤ +34V, V− ≥ −25V, and differential voltage ≤ 44V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (max) | 85Ω at +25°C, enabling low insertion loss in precision gain-setting and signal-path routing applications |
| Turn-On Time (max) | 250ns under dual-supply conditions (RL = 1kΩ, CL = 35pF), supporting >1MHz multiplexed sampling |
| Analog Signal Range | ±20V max (dual supply) or 0–12V (single supply), allowing full-rail signal handling without clipping |
| Charge Injection | −1pC typical, minimizing hold-step error in sample-and-hold circuits without external correction |
| Supply Voltage Range | Single: +5V to +34V; Split: ±5V to ±22V; differential max 44V - compatible with industrial and test-equipment rails |
| Logic Compatibility | TTL- and CMOS-compatible inputs (VIH ≥ 2.4V, VIL ≤ 0.8V), simplifying interface with microcontrollers and FPGAs |
| Leakage Current (max) | 0.5nA at +25°C, ensuring minimal signal corruption in high-impedance sensor front-ends |
Pinout & Package
Package: 16-lead TSSOP (Moisture Sensitivity Level 1, RoHS-compliant Pb-free finish per M16.173 drawing).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Active-low control inputs for Switches 1–4 (DG441 logic: IN = 0 → ON; IN = 1 → OFF) |
| 2, 15, 11, 7 | D1–D4 | Drain (output) terminals - bidirectional, matched to source pins for AC-coupled signals |
| 3, 14, 6, 4 | S1–S4 | Source (input) terminals - interchangeable with drains; low rDS(ON) ensures symmetric conduction |
| 4, 5 | V−, GND | Negative supply and logic ground reference; GND serves as common return for digital inputs |
| 13 | V+ | Positive supply terminal and substrate connection - must be tied to highest potential rail |
| 12 | NC | No internal connection - must remain unconnected per datasheet; not usable as thermal pad or ground |
Key Features
| Feature | Design Value |
|---|---|
| Bilateral SPST architecture | Enables identical performance for signal flow in either direction - critical for audio I/O and transducer interfaces |
| Low charge injection (−1pC typ) | Reduces hold-mode voltage step in sample-and-hold circuits, eliminating need for trimming capacitors |
| 44V max supply differential | Supports direct control of ±20V peak-to-peak signals without external level-shifting or clamping networks |
| Epitaxial latch-up immunity | Guarantees robust operation in noisy industrial environments with transient supply coupling or ESD events |
| Pb-free + anneal construction | RoHS-compliant termination compatible with both SnPb and lead-free reflow profiles (MSL1, JEDEC J-STD-020) |
Applications
| Audio Switching | Data Acquisition |
|---|---|
Use Scenario: Routing line-level stereo signals between multiple codecs, ADCs, and DACs in modular audio interfaces. IC Role / Device Role / Timing Role: Quad SPST analog switch providing isolated channel selection with <1pC charge injection to prevent pop/click artifacts. Use Value: Maintains signal integrity across 20Hz–20kHz bandwidth with <0.01% THD+N due to low rDS(ON) flatness and minimal crosstalk (−100dB). |
Use Scenario: Multiplexing sensor outputs (thermocouples, strain gauges) into a shared precision ADC in environmental monitoring systems. IC Role / Device Role / Timing Role: Low-leakage analog switch enabling high-input-impedance front-end switching without gain/offset drift. Use Value: 0.5nA max OFF leakage preserves microvolt-level resolution; ±20V range accommodates unconditioned sensor spans. |
| Sample and Hold Circuits | Automatic Test Equipment |
Use Scenario: Capturing fast transient waveforms in oscilloscope front-ends or power quality analyzers. IC Role / Device Role / Timing Role: Precision hold switch with sub-250ns tON/tOFF and matched ON resistance for accurate aperture time control. Use Value: Low charge injection minimizes hold-step error; 85Ω rDS(ON) ensures rapid settling into 1nF hold capacitor. |
Use Scenario: Reconfigurable signal path routing in ATE pin electronics for semiconductor functional testing. IC Role / Device Role / Timing Role: High-reliability analog switch enabling programmable DUT interface topologies with >1M cycle endurance. Use Value: 44V rating supports wide dynamic range stimulus/response measurement; −100dB crosstalk prevents channel interference during parallel testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG441BRUZ | Higher 105Ω max rDS(ON); 100ns tON; requires ≥4.5V logic swing for guaranteed switching | Better suited for low-power portable systems with strict timing budgets but less demanding on ON-resistance flatness | Select ADG441BRUZ when faster switching dominates over analog signal fidelity in battery-constrained designs |
| MAX4617ESE+ | Lower 60Ω max rDS(ON); 150ns tON; only rated for ±15V analog range and +12V/−5V dual supply max | Preferred for cost-sensitive industrial PLC I/O modules requiring tighter ON-resistance matching but narrower voltage coverage | Choose MAX4617ESE+ when operating within ±15V signal bounds and prioritizing rDS(ON) consistency over extended rail flexibility |
Compared with DG441DVZ, ADG441BRUZ trades analog precision for speed and logic margin, while MAX4617ESE+ improves ON-resistance uniformity at the expense of voltage range - making DG441DVZ optimal for wide-supply, high-fidelity analog routing where ±20V handling and sub-1pC charge injection are mandatory.

FAQ
What is the maximum allowable supply voltage difference for DG441DVZ?
The DG441DVZ supports a maximum differential voltage of 44V between V+ and V−. This allows operation with ±22V split supplies or single supplies up to +34V (with V− grounded or at −25V). Exceeding 44V risks permanent damage per absolute maximum ratings.
Does DG441DVZ support single-supply operation?
Yes, DG441DVZ supports single-supply operation from +5V to +34V. At +12V supply, it delivers 160Ω max rDS(ON) and 450ns max tON. Analog signal range is 0–12V, and logic thresholds remain TTL/CMOS-compatible with VIH ≥ 2.4V and VIL ≤ 0.8V.
How does DG441DVZ differ from DG442DVZ?
DG441DVZ and DG442DVZ share identical analog switch characteristics but differ in logic polarity: DG441DVZ turns ON when INx = 0 (low-active), while DG442DVZ turns ON when INx = 1 (high-active). Pinout, package, and electrical specs are otherwise identical.
What is the thermal resistance (θJA) of the DG441DVZ TSSOP package?
The DG441DVZ in 16-lead TSSOP has a typical junction-to-ambient thermal resistance (θJA) of 150°C/W when mounted on a standard PCB in free air. This value assumes no added copper pour or airflow; derating is required above +85°C ambient.
Is DG441DVZ pin-compatible with the legacy DG201A?
Yes, DG441DVZ is a drop-in replacement for DG201A in 16-lead TSSOP footprint. Both share identical pinout, supply requirements, and logic behavior. DG441DVZ improves upon DG201A with lower rDS(ON) (<85Ω vs. ~90Ω), faster switching (250ns vs. 350ns), and reduced charge injection.
