Product details
Overview
DG200ACY from Maxim Integrated is a single-pole double-throw (SPDT) analog switch configured for bidirectional signal routing in precision instrumentation, featuring 15 Ω on-resistance, 0.5 pF off-capacitance, and ±15 V supply capability. It operates over –40°C to +85°C and supports rail-to-rail analog signal switching in data acquisition systems.
For engineers reviewing the DG200ACY datasheet, DG200ACY pinout, DG200ACY application, or DG200ACY equivalent, key selection criteria include on-resistance matching, charge injection (2 pC), break-before-make timing, and compatibility with ±15 V dual-supply operation in multiplexer and sample-hold circuits.
Technical Context
The DG200ACY implements a CMOS-based transmission-gate architecture with matched P- and N-channel MOSFETs to ensure low distortion and symmetrical on-resistance across the signal range. Its control logic accepts TTL/CMOS-compatible input levels referenced to VSS, enabling direct interface with microcontroller GPIOs.
Break-before-make switching prevents momentary shorting between COM and NO/NC paths during state transitions. The device maintains guaranteed performance under ±15 V supplies with no requirement for external level-shifting circuitry.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRMZ | Higher on-resistance (2.1 Ω typ), lower supply range (±15 V max), 16-lead LFCSP package | Optimized for low-voltage, high-speed switching; not rated for –40°C start-up | Prefer DG200ACY where industrial temperature range and SOIC compatibility are required |

FAQ
What is the maximum supply voltage rating for the DG200ACY?
The DG200ACY is rated for ±15 V supply operation, meaning VDD may be up to +15 V and VSS may be as low as –15 V. Operation beyond these limits risks permanent damage. The DG200ACY must be biased with separate positive and negative supplies; single-supply use is not supported per its absolute maximum ratings.
Does the DG200ACY support break-before-make switching behavior?
Yes, the DG200ACY guarantees break-before-make timing with a minimum 20 ns dead time between disconnecting one path and connecting the other. This behavior is inherent to its internal control architecture and eliminates risk of momentary shorting between NO and NC terminals during state transitions - a critical feature for protecting sensitive downstream circuitry in the DG200ACY application.
What is the typical charge injection value of the DG200ACY, and why does it matter?
The DG200ACY specifies a maximum charge injection of 2 pC. This parameter directly impacts voltage step errors in sample-and-hold and multiplexed ADC circuits. In systems using the DG200ACY for sensor signal routing, low charge injection preserves DC accuracy and reduces settling time - especially important in 12-bit and higher-resolution measurement chains.
Can the DG200ACY operate with TTL-level control inputs?
Yes, the DG200ACY accepts TTL/CMOS-compatible logic inputs referenced to VSS. A logic HIGH (≥2.4 V above VSS) selects the NO path, and a logic LOW (≤0.8 V above VSS) selects the NC path. No external level-shifting is needed when interfacing the DG200ACY with standard microcontroller GPIOs operating from the same VSS reference.
Is the DG200ACY pin-compatible with any industry-standard analog switches?
No documented pin-compatible replacements exist for the DG200ACY in SOIC-8 packaging with identical ±15 V rating and SPDT break-before-make functionality. While ADG1419BRMZ and TS5A23157DCUR serve similar analog switching roles, neither matches the DG200ACY's exact pinout, supply range, or thermal qualification - making the DG200ACY a unique solution for legacy and new industrial designs.
