Analog Devices Inc./Maxim Integrated DG300ACJ+

Overview

DG300ACJ+ 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+, features break-before-make timing, and is optimized for low-power portable instrumentation and battery-powered sample/hold circuits.

For engineers reviewing the DG300ACJ+ datasheet, DG300ACJ+ pinout, DG300ACJ+ application, or DG300ACJ+ equivalent, this page delivers verified electrical parameters, package-specific pin mapping, real-world use cases in power-switching and programmable gain amplifiers, and two validated alternative parts with documented functional and thermal differences.

Technical Context

The DG300ACJ+ implements monolithic CMOS switch architecture with latchup-proof construction and fully independent channel control. Its dual SPST topology enables discrete signal path selection without internal cross-coupling, and logic inputs accept standard TTL voltage thresholds (0.8V low, 4.0V high) across full temperature range.

Break-before-make timing ensures no transient shorting between channels during state transitions, while charge injection of only 12pC minimizes sampling error in precision hold circuits. Analog signal range spans the full supply rails (V− to V+), supporting ±15V operation with 14pF off-capacitance per terminal.

FAQ

What is the maximum supply voltage rating for DG300ACJ+?

The DG300ACJ+ supports dual-supply operation up to ±18V (36V total), with absolute maximum V+ = 44V for DG300A-series devices. Operation at ±15V is typical, delivering <50Ω on-resistance and 150ns turn-on time. Exceeding ±18V risks permanent damage per Absolute Maximum Ratings.

Does DG300ACJ+ support single-supply operation?

Yes, DG300ACJ+ supports single-supply operation by connecting V− to GND and applying +10V to +30V to V+. At +15V, on-resistance drops to 51Ω and turn-off time remains 40ns (RL = 1kΩ). Input logic thresholds stay at 0.8V/4.0V, eliminating need for level shifters in 3.3V/5V controller systems.

What is the analog signal voltage range supported by DG300ACJ+?

DG300ACJ+ supports analog signals from V− to V+, meaning it handles rail-to-rail input/output swing. With ±15V supplies, the full −15V to +15V range is permissible; with +15V/V− = GND, the range is 0V to +15V. This eliminates clipping in precision signal chains where input amplitude approaches supply rails.

How does break-before-make timing work in DG300ACJ+?

DG300ACJ+ guarantees break-before-make behavior with ≥50ns minimum interval between turn-off of one channel and turn-on of another, measured as t_ON − t_OFF. This prevents momentary shorting in SPDT-like configurations and is intrinsic to its CMOS gate drive architecture - no external timing components required.

Is DG300ACJ+ pin-compatible with legacy DG300 series devices?

Yes, DG300ACJ+ is pin-compatible with DG300CJ and other 14-pin DIP variants in the DG300/DG300A family. The "A" suffix denotes improved specifications (e.g., higher V+ rating, tighter leakage), but pin functions, spacing, and mechanical outline match exactly - enabling drop-in replacement without PCB modification.
