Analog Devices Inc./Maxim Integrated DG301ACWE+T

Overview

DG301ACWE+T from Maxim Integrated is a dual SPDT CMOS analog switch IC designed for precision signal routing in low-power, bipolar-supply systems. It features <50Ω on-resistance, ±15V analog signal range (V+ to V−), 150ns turn-on time, and break-before-make switching - enabling accurate sample/hold and programmable gain amplifier functions in portable instrumentation.

For engineers reviewing the DG301ACWE+T datasheet, DG301ACWE+T pinout, DG301ACWE+T application, or DG301ACWE+T equivalent, this device supports TTL/CMOS-compatible control logic, single-supply operation (V− = GND), latchup-proof construction, and low charge injection (12pC) - critical for high-fidelity analog multiplexing and power-switching circuits.

Technical Context

The DG301ACWE+T implements two independent SPDT switches using monolithic CMOS process technology with substrate isolation. Each switch provides rail-to-rail analog conduction (V− to V+) under ±5V to ±18V dual supplies, and supports single-supply mode with V− tied to GND.

Its control architecture uses positive-logic inputs (IN1/IN2) to select between S1/D1 and S2/D2 paths, with guaranteed break-before-make timing (50ns minimum interval) and <10% channel-to-channel R_DS(ON) matching - ensuring minimal crosstalk and signal distortion during switching transitions.

FAQ

What is the operating temperature range for DG301ACWE+T?

The DG301ACWE+T is rated for 0°C to +70°C ambient operation, as indicated by the 'C' suffix in its ordering code. This commercial-grade temperature range aligns with standard industrial and portable equipment requirements, and is validated across all key parameters including R_DS(ON), leakage, and switching times per the datasheet's over-temperature electrical characteristics table.

Does DG301ACWE+T support single-supply operation?

Yes, DG301ACWE+T supports single-supply operation by connecting the V− pin to GND. In this configuration, it operates from +10V to +30V on V+, maintaining full analog signal range from GND to V+. The datasheet confirms functional performance and parameter limits (e.g., 31Ω R_DS(ON) at +30V) under single-supply conditions in Table 1.

What is the pinout compatibility of DG301ACWE+T with legacy DG301 devices?

DG301ACWE+T is pin-compatible with the original DG301CWE and DG301BWE variants in the same 16-lead wide SOIC package. All share identical pin assignments for V+, V−, GND, IN1, IN2, S1, S2, D1–D4, and N.C. terminals - enabling direct replacement without PCB modification, as confirmed in Maxim's Pin Configurations section and Ordering Information tables.

How does the break-before-make feature work in DG301ACWE+T?

In DG301ACWE+T, break-before-make is implemented per SPDT switch: when IN1 or IN2 transitions from low to high, the currently conducting path (e.g., S1→D1) opens before the alternate path (S1→D2) closes. The datasheet guarantees a minimum 50ns interval between turn-off and turn-on edges, measured per Figure 2 test circuit - preventing transient shorts in critical power or signal routing applications.

What is the maximum analog signal voltage DG301ACWE+T can switch?

DG301ACWE+T can switch analog signals from V− to V+, supporting ±15V operation with ±15V supplies. Absolute maximum ratings allow V+ up to +15V and V− down to −15V, yielding a total analog range of −15V to +15V. Signals exceeding these rails are clamped by internal diodes, but sustained operation must remain within the specified −15V to +15V linear range to maintain <50Ω R_DS(ON) and low distortion.
