Analog Devices Inc./Maxim Integrated DG417DJ

Overview

DG417DJ from Maxim Integrated is a precision, normally closed (NC), single-pole/single-throw (SPST) analog switch optimized for rail-to-rail signal routing in bipolar or single-supply systems. It features guaranteed 35Ω max on-resistance, <5nA off-leakage at +85°C, 175ns max tON, and operates from ±4.5V to ±20V or +10V to +30V supplies - ideal for sample-and-hold circuits and battery-operated test equipment.

For engineers reviewing the DG417DJ datasheet, DG417DJ pinout, DG417DJ application, or DG417DJ equivalent, key selection criteria include guaranteed RDS(ON) matching (3Ω max), low charge injection (10pC max), ESD tolerance (2000V min), and -40°C to +85°C industrial temperature range with 8-pin plastic DIP packaging.

Technical Context

The DG417DJ implements a silicon-gate CMOS architecture with integrated logic-level translation, enabling TTL/CMOS-compatible control (VL = 5V) while switching analog signals across the full supply rails. Its normally closed topology ensures fail-safe signal continuity during power loss or logic deactivation.

Guaranteed on-resistance flatness (4Ω max over signal range) and channel-to-channel RDS(ON) match (3Ω max) are specified only under bipolar-supply operation, supporting precision instrumentation where gain error and crosstalk must remain stable across input voltage swing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog switch applications.

Compared with DG417DJ, ADG1419BRUZ offers lower resistance but no NC default or matching guarantee, while TS5A23157DCUR enables ultra-low-voltage operation but sacrifices bipolar capability and industrial temperature margin - DG417DJ remains optimal for fail-safe, wide-supply, precision analog routing.

FAQ

What is the maximum analog signal voltage range supported by the DG417DJ?

The DG417DJ supports rail-to-rail analog signals from V− to V+. Under bipolar operation (±4.5V to ±20V), this yields up to ±15.5V swing. In single-supply mode (+10V to +30V, with V− tied to GND), it handles 0V to +12V signals. These ranges are validated per the Absolute Maximum Ratings table and Electrical Characteristics sections of the official Maxim datasheet for DG417DJ.

Does the DG417DJ require external pull-up or pull-down resistors on its IN pin?

No, the DG417DJ IN pin has TTL/CMOS-compatible thresholds (VINL ≤ 0.8V, VINH ≥ 2.4V) and does not require external biasing. When driven directly by a microcontroller GPIO or logic gate, it operates reliably without pull resistors. The VL pin sets logic reference, and tying VL to +5V enables direct interface with standard digital ICs - confirmed in the "Applications Information" section of the DG417DJ datasheet.

How does the DG417DJ behave during power-up or brown-out conditions?

The DG417DJ is a normally closed (NC) switch: when IN is un-driven or logic LOW, the S-to-D path remains conductive. During power-up, if V+ and V− stabilize before VL and IN, the switch defaults to ON state - preserving signal continuity in safety-critical paths. This behavior is inherent to its internal architecture and explicitly documented in the "Pin Configurations" and "Truth Tables" of the DG417DJ datasheet.

Can the DG417DJ be used with unbalanced supplies like +24V and -5V?

Yes, the DG417DJ supports unbalanced supplies as long as the difference between V+ and V− does not exceed +44V and each supply stays within its Absolute Maximum Rating (V+ ≤ 44V referenced to V−, GND ≤ 25V referenced to V−). The datasheet explicitly cites +24V/−5V as a valid configuration, and analog signal range adjusts accordingly - e.g., −5V to +24V swing - verified in the "Operation with Supply Voltages Other than ±15V" application note.

Is the DG417DJ pin-compatible with older DG417 variants such as DG417CJ?

Yes, the DG417DJ shares identical 8-pin DIP pinout, electrical interface, and functional behavior with DG417CJ and DG417CY. The primary differences are extended temperature range (−40°C to +85°C vs. 0°C to +70°C) and improved specifications including tighter RDS(ON) match (3Ω vs. unspecified) and lower leakage (<5nA vs. <10nA). Pin compatibility is confirmed in Maxim's "Ordering Information" and "Pin Description" sections for DG417DJ.
