Product details
Overview
DG200ADY+ from Maxim Integrated is a dual SPST analog switch IC with 15Ω on-resistance, ±15V supply capability, and −40°C to +85°C operating temperature range, used in precision signal routing for test equipment and industrial control systems.
For engineers reviewing the DG200ADY+ datasheet, DG200ADY+ pinout, DG200ADY+ application, or DG200ADY+ equivalent, key selection criteria include on-resistance matching (max 0.5Ω between channels), break-before-make switching, and guaranteed operation with dual ±15V supplies without external level shifters.
Technical Context
The DG200ADY+ integrates two independent single-pole single-throw (SPST) switches fabricated in Maxim's high-voltage CMOS process. Each channel supports bidirectional analog signal flow with rail-to-rail input voltage range and exhibits 0.02% THD at 1kHz under 600Ω load.
Switching is controlled by separate digital inputs compatible with TTL/CMOS logic levels. The device features 1nA maximum leakage current at 25°C and 50pF typical off-capacitance per channel, enabling low-crosstalk multiplexing in precision instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Dual SPST - enables independent control of two analog signal paths without interaction |
| On-Resistance | 15Ω max at ±15V - ensures minimal signal attenuation in 50Ω–1kΩ impedance interfaces |
| Supply Voltage | ±15V - supports direct integration into legacy industrial and test equipment power rails |
| Leakage Current | 1nA max at 25°C - preserves accuracy in high-impedance sensor front-ends |
| THD | 0.02% at 1kHz - maintains fidelity in audio and precision measurement signal chains |
| Off-Capacitance | 50pF typical - limits crosstalk and bandwidth degradation in multi-channel routing |
Pinout & Package
Package: 16-pin SOIC (Small Outline Integrated Circuit), 300 mil width, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Channel A Input/Output | Bidirectional analog terminal - no polarity constraint; connects to signal source or load |
| 3 | Channel A Control | Active-high TTL/CMOS input - drives switch ON when ≥2.4V (VDD = +15V) |
| 4, 5 | Channel B Input/Output | Bidirectional analog terminal - electrically isolated from Channel A |
| 6 | Channel B Control | Active-high TTL/CMOS input - independent timing control from Channel A |
| 7 | GND | Analog ground reference - must be tied to system AGND with low-impedance path |
| 8 | V− | Negative supply rail - required for full ±15V operation and rail-to-rail signal swing |
| 9–16 | No Connect / Reserved | Internally unused - must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Matched On-Resistance | ≤0.5Ω difference between channels - enables precise differential signal routing without gain mismatch |
| Break-Before-Make Switching | Guaranteed 10ns minimum break time - prevents momentary shorting during channel transitions |
| Rail-to-Rail Analog Range | Supports signals from V− to V+ - eliminates need for external clamping or level-shifting circuits |
| Low Charge Injection | 5pC typical - minimizes voltage glitch on sampled-hold nodes in data acquisition systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1421BRUZ | Single SPST, 1.8Ω on-resistance, ±15V rated, but only one channel per package | Requires two devices for dual-channel function; higher board area and interconnect complexity | Select when lower on-resistance is critical and space permits duplication |

FAQ
What is the maximum supply voltage range supported by the DG200ADY+?
The DG200ADY+ operates with dual supplies up to ±15V. This allows it to handle rail-to-rail analog signals in industrial and test equipment without external level-shifting circuitry. Exceeding ±15V may damage the device or degrade performance parameters such as on-resistance and leakage current. Always verify supply decoupling and grounding per Maxim's recommended layout for DG200ADY+.
Does the DG200ADY+ support break-before-make switching?
Yes, the DG200ADY+ guarantees break-before-make operation with a minimum 10ns break time between channel transitions. This prevents momentary shorting during switching, which is essential in applications like multiplexed data acquisition where signal integrity must be preserved. The timing is inherent to the internal architecture and does not require external timing control or sequencing logic for DG200ADY+.
What is the typical on-resistance matching between the two channels of the DG200ADY+?
The DG200ADY+ specifies maximum on-resistance matching of 0.5Ω between its two SPST channels. This tight matching ensures consistent gain and phase response when routing differential or parallel signals, making DG200ADY+ suitable for calibrated instrumentation and precision multiplexing where channel-to-channel variation must be minimized.
Can the DG200ADY+ be used with single-supply configurations?
No, the DG200ADY+ requires dual supplies (V+ and V−) for proper operation and rail-to-rail analog signal handling. It is not specified for single-supply use. Attempting to operate DG200ADY+ with only a positive supply and ground will result in undefined behavior, degraded on-resistance, and potential damage. Always apply both ±15V (or appropriate dual-rail) supplies per the DG200ADY+ datasheet.
What is the charge injection specification for the DG200ADY+?
The DG200ADY+ has a typical charge injection of 5pC per channel. This low value minimizes voltage glitches on high-impedance nodes-such as those found in sample-and-hold circuits or switched-capacitor filters-ensuring accurate signal capture. Charge injection is measured under standard conditions (VIN = 0V, VDD = +15V, VSS = −15V) and remains stable across temperature for DG200ADY+.
