Analog Devices Inc./Maxim Integrated DG200ACJ+

Overview

DG200ACJ+ from Maxim Integrated is a dual SPST analog switch IC with 25 Ω on-resistance, ±15 V supply capability, and −40°C to +85°C operating temperature range, used in precision signal routing for test equipment and data acquisition systems.

For engineers reviewing the DG200ACJ+ datasheet, DG200ACJ+ pinout, DG200ACJ+ application, or DG200ACJ+ equivalent, key selection factors include channel count, on-resistance matching, break-before-make timing, and rail-to-rail analog signal handling under dual-supply operation.

Technical Context

The DG200ACJ+ integrates two independent single-pole single-throw (SPST) switches fabricated using Maxim's high-voltage CMOS process. Each switch supports bidirectional analog/digital signal flow with guaranteed 25 Ω maximum on-resistance and 0.5 Ω typical on-resistance matching between channels.

It operates from dual ±5 V to ±15 V supplies or single +5 V to +30 V, with logic-compatible control inputs (TTL/CMOS) and guaranteed 10 ns propagation delay. The device features low charge injection (5 pC) and low off-leakage current (1 nA at 25°C), critical for sample-and-hold and multiplexer applications.

FAQ

What is the maximum supply voltage rating for the DG200ACJ+?

The DG200ACJ+ supports dual-supply operation from ±5 V to ±15 V, meaning its absolute maximum analog supply rating is V+ = +15 V and V− = −15 V. Exceeding these values risks permanent damage. The DG200ACJ+ also operates from single supplies up to +30 V, with GND referenced to V−. Always observe polarity and voltage limits specified in the official Maxim datasheet for DG200ACJ+.

Does the DG200ACJ+ support break-before-make switching?

Yes, the DG200ACJ+ guarantees break-before-make timing of at least 10 ns between channel transitions. This prevents momentary short-circuit conditions during switching, which is essential in multiplexer configurations where signal sources must not be inadvertently connected. The DG200ACJ+ achieves this via internal timing control - no external circuitry is needed to enforce safe switching sequence.

What is the typical on-resistance matching between the two channels of the DG200ACJ+?

The DG200ACJ+ provides typical on-resistance matching of 0.5 Ω between its two SPST switches, with a maximum mismatch of 0.5 Ω across temperature and supply variations. This tight matching ensures consistent gain and phase response in differential or ratiometric measurement paths. The DG200ACJ+ datasheet specifies this value under standard test conditions (V_DD = ±15 V, T_A = 25°C).

Can the DG200ACJ+ be used with TTL-level control signals?

Yes, the DG200ACJ+ accepts TTL- and CMOS-compatible logic inputs: logic high is defined as ≥2.0 V, and logic low as ≤0.8 V, with full compatibility down to 3.3 V and 5 V microcontroller GPIOs. No level-shifting circuitry is required. The DG200ACJ+ control pins (IN1, IN2, EN1, EN2) are designed for direct interface with standard digital logic families without additional components.

Is the DG200ACJ+ RoHS-compliant and lead-free?

Yes, the DG200ACJ+ is RoHS-compliant and lead-free, meeting EU Directive 2011/65/EU and IPC/JEDEC J-STD-609B Class 3 standards. The "+" suffix in DG200ACJ+ explicitly denotes lead-free, halogen-free, and RoHS-compliant packaging. This applies to the 16-pin SOIC package (JEDEC MS-012AC) supplied by Maxim Integrated and distributed through authorized channels.
