Renesas DG411DYZ

Overview

DG411DYZ from Renesas Electronics is a monolithic quad SPST CMOS analog switch with TTL/CMOS-compatible digital inputs, 35Ω max ON-resistance, 175ns max turn-on time, and ±20V dual-supply operation. It serves as a drop-in replacement for DG211-series switches in precision signal routing applications such as data acquisition and sample-and-hold circuits.

For engineers reviewing the DG411DYZ datasheet, DG411DYZ pinout, DG411DYZ application, or DG411DYZ equivalent, key selection criteria include its low charge injection (5pC typ), bilateral signal handling, -40°C to +85°C operating range, SOIC-16 Pb-free package, and compatibility with single (5–44V) or split (±5V to ±20V) supplies.

Technical Context

The DG411DYZ implements four independent SPST switches using a high-voltage silicon-gate CMOS process with epitaxial isolation to prevent latch-up. Its logic control uses active-low enable (INx = 0V → switch ON), matching DG211/DG411 polarity.

Each switch supports bidirectional analog signals up to ±15V with minimal ON-resistance variation, and features matched source/drain OFF capacitance (9pF typ) and high OFF isolation (68dB at 1MHz), enabling clean channel separation in multiplexed systems.

Key Specifications

Pinout & Package

FAQ

What is the logic polarity of DG411DYZ control inputs?

The DG411DYZ uses active-low logic: a logic "0" (≤0.8V) on IN1–IN4 turns the corresponding switch ON, while a logic "1" (≥2.4V) turns it OFF. This matches DG211/DG411 behavior and differs from DG412's active-high logic. DG411DYZ maintains consistent polarity across all four channels, simplifying firmware control in multiplexed systems.

Can DG411DYZ operate from a single 5V supply?

Yes, DG411DYZ supports single-supply operation from +5V to +44V. For 5V use, connect V+ to +5V, V− to GND, and VL to +5V. Analog signal range is then 0V to 5V. Note that the 5V VL requirement remains mandatory-even with single supply-to meet TTL input thresholds; this is explicitly verified in the datasheet's single-supply electrical specifications table.

What is the maximum analog signal voltage supported by DG411DYZ?

DG411DYZ supports analog signals up to ±15V when operated with dual supplies (e.g., ±15V), or 0V to +12V with single +12V supply. The absolute maximum rating is V+ to V− ≤ 44V, permitting 40V_P-P signal handling. Exceeding ±15V analog swing risks increased ON-resistance variation and reduced linearity, as confirmed by Figure 8 (ON-resistance vs. drain voltage) in the DG411DYZ datasheet.

Does DG411DYZ require external pull-up or pull-down resistors on its logic inputs?

No, DG411DYZ does not require external biasing on IN1–IN4. Its digital inputs exhibit ultra-low leakage (±0.5µA max IIH/IIL), and the internal structure ensures valid logic states with direct connection to TTL/CMOS outputs. External resistors are unnecessary unless floating-input prevention is needed in high-noise environments-per standard PCB layout practice, not a DG411DYZ requirement.

How does DG411DYZ handle charge injection in sample-and-hold applications?

DG411DYZ specifies 5pC typical charge injection (Q), measured with CL = 10nF and RG = 0Ω. This low value minimizes voltage step errors on hold capacitors-e.g., a 10nF cap experiences only 0.5mV perturbation-reducing need for trimming or correction algorithms. The datasheet confirms this performance is maintained across the full ±15V analog range, making DG411DYZ especially effective in precision S/H circuits where accuracy and repeatability are critical.
