Product details
Overview
DG300ACWE from Maxim Integrated is a dual single-pole single-throw (SPST) CMOS analog switch with TTL/CMOS-compatible control inputs, <50Ω on-resistance, 150ns turn-on time, and ±5V to ±18V dual-supply operation. It supports rail-to-rail analog signal switching from V− to V+ and is optimized for low-power portable instrumentation and battery-powered sample/hold circuits.
For engineers reviewing the DG300ACWE datasheet, DG300ACWE pinout, DG300ACWE application, or DG300ACWE equivalent, this page delivers verified electrical specs, package dimensions, break-before-make timing, charge injection (12pC), and real-world selection guidance for analog signal routing in precision, low-leakage, and fast-switching designs.
Technical Context
The DG300ACWE implements monolithic CMOS switch architecture with latchup-proof construction and fully independent channel control logic. Each SPST switch features break-before-make operation, low charge injection (12pC), and matched on-resistance (<50Ω typ at ±15V) across the full analog range.
It operates over ±5V to ±18V supplies or single +10V to +30V (with V− tied to GND), enabling direct interface with legacy TTL logic and modern low-voltage microcontrollers. Analog signal handling extends from V− to V+, supporting bipolar signal paths without level-shifting.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Higher on-resistance (1.3Ω min), wider supply range (±5V to ±22V), 16-lead TSSOP package. | Designed for higher-voltage industrial PLC I/O modules; not pin-compatible with DG300ACWE. | Select ADG1419BRUZ only when >±18V operation or lower RON temperature drift is required. |
| TS5A23157DRCR | Lower voltage rating (+5.5V max), 10-lead WSON package, 0.9Ω typical RON, but no dual-supply support. | Targeted at single-supply consumer electronics; lacks bipolar signal handling capability. | Choose TS5A23157DRCR only for cost-sensitive, low-voltage, space-constrained designs where ± supplies are unavailable. |
Compared with ADG1419BRUZ and TS5A23157DRCR, the DG300ACWE uniquely balances ±18V operation, sub-50Ω on-resistance, and 16-pin SOIC compatibility-making it the preferred choice for legacy-compatible, bipolar-signal, medium-speed analog routing in portable test gear.

FAQ
What is the maximum supply voltage rating for DG300ACWE?
The DG300ACWE supports dual-supply operation up to ±18V (36V total). Its absolute maximum V+ rating is 44V for DG300A variants, but DG300ACWE - as an "A" suffix part - is rated for ±18V continuous operation. Exceeding this may cause permanent damage. Always observe the ±18V limit in both steady-state and transient conditions when using DG300ACWE in system design.
Does DG300ACWE support single-supply operation?
Yes, DG300ACWE supports single-supply operation from +10V to +30V by connecting V− to GND. In this configuration, the analog signal range remains rail-to-rail (0V to V+), and all timing and leakage specifications remain valid. The device retains TTL/CMOS logic compatibility and requires no external level-shifting circuitry when driven by standard microcontrollers.
What is the pinout compatibility of DG300ACWE with other DG300-series devices?
DG300ACWE uses the 16-lead wide SOIC package and shares identical pin assignments with DG300CWE, DG300BWE, and DG300ACWE's own family members. However, it is not pin-compatible with 14-lead DIP or CERDIP versions (e.g., DG300CJ, DG300CK), nor with 10-lead metal can packages. Pin mapping is strictly defined in the DG300A datasheet Figure 1 and confirmed for DG300ACWE in the Ordering Information table.
How does charge injection affect performance in sample-and-hold circuits using DG300ACWE?
DG300ACWE exhibits 12pC typical charge injection, measured with ±15V supplies and 10nF load. In sample-and-hold applications, this injects a voltage error ΔV = Q/CHOLD; for a 1nF hold capacitor, error is 12mV. To minimize impact, use larger hold capacitance (>10nF), guard traces, and ensure low-impedance driving sources. DG300ACWE's consistent 12pC value enables predictable compensation in precision designs.
Is DG300ACWE suitable for use in automotive applications?
DG300ACWE is specified for 0°C to +70°C operation and is not qualified to AEC-Q100 standards. While its ±18V rating and low leakage suit some under-hood signal conditioning tasks, it lacks automotive-grade qualification, extended temperature screening, and failure-in-time (FIT) data. For automotive use, consider Maxim's automotive-qualified alternatives like MAX4617 or ADI's ADG1419 with AEC-Q100 Grade 2 certification instead of DG300ACWE.
