Product details
Overview
DG419CJ+ from Maxim Integrated is a precision SPDT analog switch with normally closed (S1) and normally open (S2) channels, 35Ω max on-resistance, <5nA off-leakage at +85°C, and 10pC max charge injection. It operates from ±4.5V to ±20V or +10V to +30V supplies and supports rail-to-rail signal handling in audio routing and test equipment.
For engineers reviewing the DG419CJ+ datasheet, DG419CJ+ pinout, DG419CJ+ application, or DG419CJ+ equivalent, key selection criteria include guaranteed 3Ω on-resistance matching between S1/S2 channels, 4Ω on-resistance flatness over full signal range, break-before-make timing (5–13ns), and 2000V ESD tolerance per Method 3015.7.
Technical Context
The DG419CJ+ uses a 44V silicon-gate CMOS process enabling bipolar ±4.5V to ±20V or single +10V to +30V operation. Its SPDT architecture integrates two independent switches sharing one drain (D), with separate source terminals S1 (NC) and S2 (NO), controlled by a single TTL/CMOS-compatible logic input (IN).
On-resistance matching (≤3Ω) and flatness (≤4Ω) are guaranteed only under bipolar-supply conditions. Charge injection (≤10pC) and off-leakage (<5nA at +85°C) are specified across the full operating temperature range (0°C to +70°C), with switching times tON ≤175ns and tOFF ≤145ns at ±15V.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRZ | Higher RDS(ON) (1.3Ω typ), lower leakage (100pA typ), but requires ≥±5V supplies and lacks guaranteed RDS(ON) matching | Better for ultra-low-leakage precision instrumentation; unsuitable where 3Ω matching is required for channel balancing | Select ADG1419BRZ only if sub-nA leakage dominates design priority and supply rails support ±5V minimum |
| TS5A3159DCKR | Lower voltage rating (+5.5V max), higher RDS(ON) (1.2Ω typ), no bipolar support, but offers 1.8V logic compatibility | Targeted at low-voltage portable electronics; cannot replace DG419CJ+ in ±15V industrial or test systems | Choose TS5A3159DCKR only for 3.3V/1.8V logic domains with ≤5.5V analog rails - not a functional substitute in legacy ±15V designs |
Compared with ADG1419BRZ and TS5A3159DCKR, the DG419CJ+ uniquely delivers guaranteed 3Ω on-resistance matching and 4Ω flatness under bipolar operation - essential for dual-channel calibration, differential signal routing, and military-grade test equipment where channel tracking is mandatory.

FAQ
What is the maximum supply voltage range supported by the DG419CJ+?
The DG419CJ+ operates from ±4.5V to ±20V bipolar supplies or a single +10V to +30V supply. Absolute maximum ratings specify V+ ≤ 44V referenced to V−, and GND ≤ 25V referenced to V−. Exceeding these stresses may cause permanent damage, and operation outside the recommended ranges invalidates parametric guarantees including RDS(ON) matching and flatness.
Does the DG419CJ+ support rail-to-rail analog signal switching?
Yes, the DG419CJ+ supports rail-to-rail analog signal handling - signals from V− to V+ are passed without clipping. This capability is confirmed in the Electrical Characteristics table and Typical Operating Characteristics (DG417-03, DG417-04), and applies across its full specified supply range, enabling full utilization of ±15V or +24V system rails.
What is the guaranteed on-resistance matching specification for DG419CJ+?
The DG419CJ+ guarantees ΔRDS(ON) ≤ 3Ω between its S1 and S2 channels under bipolar-supply operation (e.g., ±15V). This matching is 100% tested and specified over the full temperature range (0°C to +70°C), making it suitable for applications requiring matched gain or attenuation such as differential signal routing and calibration paths.
How does the DG419CJ+ handle logic-level compatibility?
The DG419CJ+ accepts TTL- or CMOS-compatible logic inputs via the IN pin. VL must be set to +5V for TTL compatibility or tied to V+ for CMOS-level thresholds. Input voltage thresholds are defined as VINL ≤ 0.8V and VINH ≥ 2.4V (with VL = 5V), and logic current is limited to ±0.5µA - ensuring low loading on microcontroller or FPGA GPIOs.
Is the DG419CJ+ pin-compatible with older DG419 variants?
Yes, the DG419CJ+ is a direct plug-in upgrade for industry-standard DG419 devices in 8-pin DIP packages. Pinout, electrical behavior, and timing specifications are identical to legacy DG419 parts, with improvements in RDS(ON) matching, flatness, charge injection, and off-leakage - requiring no PCB or firmware changes for drop-in replacement.
