Product details
Overview
DG441DYZ-T from Intersil is a monolithic quad SPST CMOS analog switch IC with TTL/CMOS-compatible digital inputs, 85Ω max ON resistance, 250ns max turn-on time, and ±20V analog signal range. It operates from single (5–34V) or split (±5V to ±22V) supplies and serves as a drop-in replacement for DG201A/DG202 in precision sample-and-hold and audio routing circuits.
For engineers reviewing the DG441DYZ-T datasheet, DG441DYZ-T pinout, DG441DYZ-T application, or DG441DYZ-T equivalent, this page delivers verified electrical specs, SOIC-16 package details, real-world use cases in data acquisition and battery-powered systems, and two confirmed alternative parts with functional and logic-polarity differences.
Technical Context
The DG441DYZ-T implements four independent bilateral SPST switches using a high-voltage silicon-gate CMOS process with epitaxial latch-up protection. Its logic control is active-low: INx = ≤0.8V enables conduction (ON), while ≥2.4V disables (OFF).
It supports 44V max V+–V− differential, ±25V GND-to-V−, and +34V GND-to-V+, enabling ±20V analog signal switching without clipping. Charge injection is minimized to ±1pC (typ), critical for low-error sample-and-hold operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance | 85Ω max at +25°C, ±15V supplies - ensures minimal signal attenuation and gain error in precision resistor-programmed amplifiers. |
| Turn-On Time | 250ns max - enables fast multiplexing in 1MSPS data acquisition systems with minimal aperture jitter. |
| Analog Signal Range | ±20V max - supports full-rail switching of industrial sensor outputs and audio line-level signals. |
| Supply Range | Single: +5V to +34V; Split: ±5V to ±22V - accommodates legacy 5V logic and modern high-voltage industrial rails. |
| Charge Injection | ±1pC typ - reduces hold-mode voltage step error below 100μV in 1nF hold capacitors, easing anti-aliasing filter design. |
| OFF Isolation | 60dB min at 1MHz - suppresses crosstalk between adjacent channels in multi-signal routing applications. |
| Logic Thresholds | VIL ≤0.8V, VIH ≥2.4V - ensures robust interfacing with both 3.3V and 5V microcontrollers without level shifters. |
Pinout & Package
DG441DYZ-T is housed in a 16-lead SOIC package (JEDEC MS-012-AC, M16.15), Pb-free with matte tin terminations, rated for reflow soldering and suitable for automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Active-low digital control inputs - drive corresponding switch ON when ≤0.8V (TTL/CMOS compatible). |
| 2, 15, 10, 7 | D1–D4 | Drain (output) terminals - bidirectional; connect to load or downstream circuitry. |
| 3, 14, 11, 6 | S1–S4 | Source (input) terminals - bidirectional; accept analog signals up to ±20V. |
| 4 | V− | Negative supply rail - must be ≤ −25V relative to GND; sets lower bound of analog signal range. |
| 5 | GND | Logic common reference - ties digital input thresholds and internal bias networks. |
| 12 | NC | No internal connection - must remain unconnected; no pull-up/down or bypass required. |
| 13 | V+ | Positive supply rail (substrate tie) - must be ≤ +34V relative to GND; defines upper analog rail limit. |
Key Features
| Feature | Design Value |
|---|---|
| Bilateral analog switching | Identical rDS(ON) and capacitance in either direction - enables flexible signal path routing without polarity constraints. |
| Low charge injection (±1pC) | Minimizes voltage glitch on hold capacitors - eliminates need for trimming resistors in precision S/H circuits. |
| Drop-in DG201A/DG202 upgrade | Same pinout and function with improved speed and ON resistance - allows direct PCB replacement without layout changes. |
| Latch-up immune process | Epitaxial layer prevents destructive latch-up under transient overvoltage - enhances reliability in noisy industrial environments. |
| Pb-free RoHS compliance | Matte tin termination with anneal - qualified for SnPb and Pb-free reflow, meeting IPC/JEDEC J-STD-020 MSL ratings. |

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 |
|---|---|---|---|
| MAX4617ESE+ | Pin-compatible but active-high logic (INx = HIGH = ON); 60Ω max rDS(ON); 100ns tON. | Requires inverted control signals; better for high-speed multiplexing where logic inversion is acceptable. | Select MAX4617ESE+ only if system firmware can invert control lines and faster switching is prioritized over direct DG201A replacement. |
| ADG441BRZ | Same active-low logic and pinout; 75Ω max rDS(ON); 180ns tON; wider temp range (−40°C to +125°C). | Superior thermal performance for automotive under-hood or industrial high-temp deployments. | Choose ADG441BRZ when extended temperature operation or marginally lower ON resistance is required, accepting same footprint and logic behavior. |
Compared with DG441DYZ-T, MAX4617ESE+ offers faster switching but demands logic inversion, while ADG441BRZ provides tighter ON resistance and extended temperature capability without changing control architecture or layout.

FAQ
What is the maximum analog signal voltage the DG441DYZ-T can switch?
The DG441DYZ-T supports an analog signal range of ±20V maximum, defined by its absolute rating of V+ to V− ≤ 44V and GND-to-V− ≥ −25V / GND-to-V+ ≤ +34V. This allows full-rail switching of industrial sensor outputs and line-level audio signals without distortion or damage when supplies are properly biased.
Is DG441DYZ-T pin-compatible with the older DG201A series?
Yes, DG441DYZ-T is a documented drop-in replacement for DG201A and DG202, sharing identical 16-pin SOIC pinout, logic polarity (active-low), and functional block diagram. No PCB layout changes are needed - only verify supply voltages and signal levels match the improved 44V max V+–V− rating.
Does DG441DYZ-T support single-supply operation?
Yes, DG441DYZ-T operates from a single supply ranging from +5V to +34V. In this mode, V− is tied to ground, V+ connects to the positive rail, and the analog signal range becomes 0V to V+ (e.g., 0–12V at V+ = 12V), with 160Ω max rDS(ON) and 450ns max tON.
What is the significance of the "-T" suffix in DG441DYZ-T?
The "-T" suffix indicates tape-and-reel packaging: DG441DYZ-T is supplied in 2,500-unit reels optimized for automated SMT placement. The base marking remains "DG441DYZ", confirming Pb-free SOIC construction per JEDEC M16.15, with matte tin terminations qualified for both SnPb and Pb-free reflow.
How does the DG441DYZ-T handle charge injection in sample-and-hold circuits?
DG441DYZ-T specifies ±1pC typical charge injection, measured with CL = 1nF and RG = 0Ω. This results in sub-100μV hold-step error in standard 1nF hold capacitors, eliminating the need for external nulling resistors and simplifying precision S/H design compared to older DG201A (±5pC typical).
