Vishay Siliconix DG613DJ

Overview

DG613DJ from Vishay Siliconix is a high-speed, low-glitch quad analog switch IC with two normally open (NO) and two normally closed (NC) SPST switches in a 16-pin plastic DIP package. It features 12 ns turn-on time, 18 Ω on-resistance, ±2 pC charge injection, 500 MHz bandwidth, and operates from ±10 V analog supplies with 5 V CMOS logic compatibility - used in pixel-rate video switching and DAC deglitching.

For engineers reviewing the DG613DJ datasheet, DG613DJ pinout, DG613DJ application, or DG613DJ equivalent, key selection criteria include verified SPST/SPDT reconfigurability, guaranteed 12 ns t_ON at 3 pF load, low 2 pC charge injection for sample-and-hold accuracy, and dual-supply operation supporting ±10 V analog signal range.

Technical Context

The DG613DJ integrates four independent lateral DMOS analog switches fabricated using Vishay's proprietary D/CMOS process, combining n-channel DMOS FETs with low-power CMOS control logic and on-chip level translators. Each switch conducts bidirectionally when ON and blocks up to 16 V_p-p when OFF.

Its logic interface accepts 0 V / 5 V inputs (V_IL ≤ 1 V, V_IH ≥ 4 V), supports separate logic supply (V_L) from 4 V to V₊, and includes epitaxial isolation to prevent latch-up. The device enables flexible configurations: four independent SPST, two SPDT, or one DPDT via external wiring of IN/OUT pins.

Key Specifications

FAQ

What is the maximum analog signal voltage range supported by the DG613DJ?

The DG613DJ supports an analog signal range from V– to (V+ – 5) V. With recommended operating conditions of V+ = 15 V and V– = –3 V, this yields a usable analog range of –3 V to +10 V - sufficient for ±10 V industrial sensor interfaces and video signal levels. Absolute maximum ratings allow V+ to V– up to 21 V, but sustained operation beyond the recommended range may degrade R_DS(on) matching and leakage performance. Always verify actual signal swing against the DG613DJ's specified VANALOG limits in your design.

Can the DG613DJ be configured as a dual SPDT switch?

Yes, the DG613DJ can be wired as two independent SPDT switches using its two normally open (IN1/IN4 → S1/D1, S4/D4) and two normally closed (IN2/IN3 → S2/D2, S3/D3) SPST sections. By connecting S1 and S2 to a common input, D1 and D3 to one output, and D2 and D4 to another output, users achieve true break-before-make SPDT behavior. This configuration is explicitly validated in Vishay's Application Note AN207 and leverages the DG613DJ's unique NO/NC architecture - a capability not available in standard SPST-only alternatives like the DG611DJ.

Does the DG613DJ require external pull-up or pull-down resistors on its digital inputs?

No, the DG613DJ does not require external pull-up or pull-down resistors. Its digital inputs (IN1–IN4) have CMOS-compatible thresholds (V_IL ≤ 1 V, V_IH ≥ 4 V) and exhibit low input current (<1 µA over temperature), allowing direct connection to 5 V microcontroller GPIOs or FPGA outputs. Internal protection diodes clamp inputs exceeding V+ or V–, but external series resistors (≥1 kΩ) are recommended if driving from high-impedance or noisy sources to limit fault current per Absolute Maximum Ratings.

How does the DG613DJ's charge injection performance impact sample-and-hold accuracy?

The DG613DJ's guaranteed ±2 pC charge injection directly determines hold-step error magnitude in sample-and-hold circuits. For a 1 nF hold capacitor, this produces a maximum voltage step of |ΔV| = Q/C = 2 mV - well within 12-bit (±1.2 mV) and acceptable for 10-bit (±5 mV) systems. This low value results from minimized parasitic capacitance and optimized DMOS gate geometry in Vishay's D/CMOS process. When used with low-leakage polystyrene or polypropylene capacitors, the DG613DJ enables sub-10 ns aperture uncertainty and <0.1% droop over 100 µs hold times - critical for high-fidelity digitization in oscilloscopes and spectrum analyzers.

Is the DG613DJ pin-compatible with other devices in the DG611/DG612/DG613 family?

Yes, the DG613DJ shares identical pinout and package (16-pin plastic DIP) with DG611DJ and DG612DJ, enabling drop-in replacement in existing layouts. However, logic polarity differs: DG611DJ turns switches ON with logic LOW, DG612DJ with logic HIGH, while DG613DJ uses complementary control (IN1/IN4 = ON for logic HIGH, IN2/IN3 = ON for logic LOW). No PCB changes are required, but firmware or logic-level translation may be needed to maintain functional equivalence. All three parts share identical analog specifications, thermal characteristics, and absolute maximum ratings.
