Analog Devices Inc./Maxim Integrated DG413CUE+T

Overview

DG413CUE+T from Maxim Integrated is a quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, designed for precision signal routing in bipolar or single-supply systems. It delivers 35Ω max on-resistance, <5nA off-leakage at +85°C, and 150ns max tON - enabling reliable operation in battery-powered test equipment and audio routing applications.

For engineers reviewing the DG413CUE+T datasheet, DG413CUE+T pinout, DG413CUE+T application, or DG413CUE+T equivalent, key selection criteria include guaranteed R_DS(ON) matching (≤3Ω), rail-to-rail analog signal handling (±15V), TTL/CMOS logic compatibility, and ESD tolerance of ≥2000V per Method 3015.7.

Technical Context

The DG413CUE+T implements four independent CMOS transmission gates fabricated in a 44V silicon-gate process, supporting dual-supply (±4.5V to ±20V) or single-supply (+10V to +30V) operation. Its break-before-make timing (25ns typ.) prevents signal shorting during channel switching, and charge injection is limited to 10pC max - critical for sample-and-hold accuracy.

All four switches share common V+, V−, GND, and VL pins, with separate INx, Dx, and Sx terminals enabling bidirectional signal flow. On-resistance flatness (Δ4Ω max) is guaranteed across the full analog range (±15.5V), and leakage performance is 100% tested at +85°C per data sheet Note 7.

Key Specifications

Pinout & Package

FAQ

What is the maximum analog signal voltage range supported by DG413CUE+T?

DG413CUE+T supports an analog signal range of ±15.5V when operated with ±16.5V supplies, and 0V to +12V with a +12V single supply. This rail-to-rail capability ensures full dynamic range utilization in both industrial and portable systems. The device's internal clamping diodes protect against overvoltage, but signals must remain within (V− −2V) to (V+ +2V) to avoid damage. DG413CUE+T maintains specified R_DS(ON) flatness only within the guaranteed ±15.5V range.

Does DG413CUE+T require separate logic and analog grounds?

No - DG413CUE+T uses a single GND pin shared by logic and analog sections, simplifying PCB layout. However, best practice requires star grounding near the device with separate analog and digital ground planes joined at that point to minimize noise coupling. The VL pin must be decoupled to GND with a 0.1µF ceramic capacitor, and V+/V− should use local 1µF + 0.1µF bypassing. DG413CUE+T's 35µW max power dissipation minimizes ground current interference.

Can DG413CUE+T operate with unbalanced supplies like +24V and −5V?

Yes - DG413CUE+T supports unbalanced supplies as long as the total voltage difference (V+ − V−) does not exceed +44V and each rail stays within absolute maximum ratings. For example, +24V/V− = −5V yields 29V differential - well within limit. Analog signal range becomes asymmetric (−5V to +24V), and R_DS(ON) flatness is not guaranteed outside bipolar-symmetric operation. DG413CUE+T's design accommodates this flexibility without derating other parameters.

What is the purpose of the VL pin on DG413CUE+T, and how should it be connected?

The VL pin sets the logic threshold voltage for IN1–IN4 inputs. Connect VL to +5V for TTL compatibility (2.4V high, 0.8V low), or tie VL to V+ for CMOS-level operation (V+/2 threshold). Do not leave VL floating - it must be actively driven. A 0.1µF decoupling capacitor between VL and GND is mandatory to suppress logic noise from affecting analog performance. DG413CUE+T's internal level-shifting circuitry ensures correct switch actuation regardless of VL choice.

How does DG413CUE+T achieve its low charge injection specification of 10pC max?

DG413CUE+T achieves 10pC max charge injection through matched transistor geometry in its CMOS transmission gates and optimized gate drive timing that balances capacitive coupling from control lines. This is verified under CL = 1.0nF, V_GEN = 0V, R_GEN = 0Ω per Figure 4 in the datasheet. The low value directly translates to <1mV glitch on a 10nF hold capacitor - essential for 12-bit+ data acquisition. DG413CUE+T's charge injection remains stable across temperature and supply voltage, unlike many alternatives that degrade above +70°C.
