Analog Devices Inc./Maxim Integrated DG411CJ

Overview

DG411CJ from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in bipolar or single-supply systems. It features 35Ω max on-resistance, <5nA off-leakage at +85°C, 10pC max charge injection, rail-to-rail analog signal handling (±15V), and TTL/CMOS-compatible logic inputs - enabling use in sample-and-hold circuits and battery-operated test equipment.

For engineers reviewing the DG411CJ datasheet, DG411CJ pinout, DG411CJ application, or DG411CJ equivalent, key selection criteria include guaranteed on-resistance matching (≤3Ω), flatness over signal range (Δ4Ω), ESD tolerance (2000V min), low power consumption (35µW max), and compatibility with ±4.5V to ±20V or +10V to +30V supplies.

Technical Context

The DG411CJ implements four independent NC SPST switches fabricated using a 44V silicon-gate process, supporting bidirectional conduction with matched channel characteristics. Its architecture guarantees low R_DS(ON) flatness (Δ4Ω) and tight inter-channel on-resistance matching (≤3Ω) under bipolar supply operation.

Switching is controlled by TTL/CMOS-compatible digital inputs referenced to VL (typically +5V), with logic thresholds of VINH = 2.4V and VINL = 0.8V. The device maintains rail-to-rail analog signal integrity across V_ANALOG = ±15V while delivering t_ON < 150ns and t_OFF < 100ns at ±15V supplies.

Key Specifications

Pinout & Package

DG411CJ is housed in a 16-pin plastic DIP package (package code P16-1), with through-hole mounting and 0.300" wide body. Pin 1 is located at the top-left corner when viewed from the top with notch or dot orientation.

FAQ

What is the maximum analog signal voltage range supported by DG411CJ?

DG411CJ supports a rail-to-rail analog signal range of ±15V when operated with ±15V supplies. This is defined by the absolute maximum ratings and confirmed in Electrical Characteristics tables. The actual usable range scales with supply voltage - for example, ±10V supplies yield ±9.5V typical analog swing. DG411CJ must never be subjected to analog signals exceeding V+ or falling below V−, as internal clamping diodes will conduct.

Is DG411CJ pin-compatible with the original industry-standard DG411?

Yes, DG411CJ is a plug-in upgrade for the legacy DG411 and maintains identical pinout, footprint, and logic behavior. The datasheet explicitly states "Plug-In Upgrade for Industry-Standard DG411/DG412/DG413" and confirms matching DIP-16 packaging and functional diagrams. No PCB layout changes are required when replacing older DG411 variants with DG411CJ.

What logic voltage should be applied to VL for TTL compatibility with DG411CJ?

For TTL compatibility, VL must be set to +5V. The datasheet specifies VINH = 2.4V and VINL = 0.8V under VL = 5V conditions, ensuring reliable recognition of standard TTL logic levels. Applying VL = V+ instead configures the inputs for CMOS thresholds, which require higher logic-high voltage and is not recommended when interfacing with 5V TTL microcontrollers or FPGAs.

Does DG411CJ support single-supply operation, and how is it configured?

Yes, DG411CJ supports single-supply operation from +10V to +30V. To configure: tie V− to GND, connect VL to +5V for TTL compatibility, and ensure analog signals remain within 0V to V+ − 1V (due to internal level-shifting). The datasheet confirms this in "Operation with Supply Voltages Other Than 15V" and lists +12V single-supply electrical characteristics with VANALOG = 0V to 12V.

How does DG411CJ achieve low charge injection, and why is it important?

DG411CJ achieves ≤10pC max charge injection via matched transistor geometry and optimized gate drive timing, as guaranteed in the New Features section. This low value is critical in sample-and-hold circuits because injected charge causes voltage step errors on the hold capacitor, directly degrading DC accuracy and settling time - especially in high-resolution data acquisition systems where sub-mV errors are unacceptable.
