Renesas DG401DVZ-T

Overview

DG401DVZ-T from Intersil is a dual single-pole single-throw (SPST) monolithic CMOS analog switch with TTL/CMOS-compatible digital inputs, 45 Ω maximum ON resistance, 150 ns maximum turn-on time, and ±15 V analog signal range - used in precision sample-and-hold circuits, data acquisition front-ends, and battery-powered instrumentation.

For engineers reviewing the DG401DVZ-T datasheet, DG401DVZ-T pinout, DG401DVZ-T application, or DG401DVZ-T equivalent, this page delivers verified electrical specs, TSSOP-16 package details, real-world use scenarios, and two validated alternative parts for design continuity and sourcing flexibility.

Technical Context

The DG401DVZ-T implements two independent bilateral SPST switches using a high-voltage silicon-gate CMOS process, enabling operation across ±5 V to ±17 V split supplies or +5 V to +34 V single supply. Its epitaxial layer prevents latch-up, supporting robust operation in hi-rel systems.

Each switch exhibits low charge injection (<60 pC), minimal ON-resistance variation over ±15 V analog input range, and matched r_DS(ON) (≤5 Ω channel-to-channel delta), making it suitable for precision multiplexing and signal routing where distortion and settling error must be minimized.

FAQ

What is the maximum analog signal voltage supported by the DG401DVZ-T?

The DG401DVZ-T supports analog signals up to ±15 V when operated within its specified supply rails (±5 V to ±17 V). This is defined by the Absolute Maximum Rating of V+ to V− ≤ 44 V and the guaranteed Analog Signal Range specification. Exceeding ±15 V may cause substrate diode conduction and increased leakage, so design margins should maintain VANALOG within this bound for reliable operation. The DG401DVZ-T datasheet confirms this limit across all temperature ranges.

Is the DG401DVZ-T pin-compatible with the DG401DY or DG401DYZ variants?

Yes - the DG401DVZ-T shares identical pinout and electrical specifications with DG401DY and DG401DYZ, differing only in package (TSSOP vs SOIC) and RoHS compliance method (Pb-free plus anneal). All three use the same M16.173 (TSSOP) or M16.15 (SOIC) footprint, allowing direct PCB substitution where board space and thermal requirements permit. The DG401DVZ-T pinout matches Figure 1 on page 2 of FN3284 Rev 11.00.

Does the DG401DVZ-T require external pull-up or pull-down resistors on its digital inputs?

No - the DG401DVZ-T features TTL/CMOS-compatible digital inputs with guaranteed thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.4 V) and ultra-low input current (±1 μA max), eliminating the need for external biasing. Direct connection to microcontroller GPIOs or FPGA outputs is fully supported. Input rise/fall times must remain ≤20 ns per datasheet Note 3, which is achievable without added RC networks in typical digital interfaces.

Can the DG401DVZ-T operate from a single +12 V supply while switching ±10 V analog signals?

No - the DG401DVZ-T cannot switch analog signals beyond the V+ and V− rails. With only +12 V applied to V+ and GND to V−, the maximum allowable analog swing is 0 V to +12 V. To handle ±10 V signals, split supplies (e.g., V+ = +12 V, V− = −12 V) or a higher single supply (≥+20 V) with level-shifted signal references are required. The DG401DVZ-T datasheet explicitly states analog signal range is bounded by the supply rails.

What is the thermal resistance (θ_JA) of the DG401DVZ-T in its TSSOP package?

The DG401DVZ-T in 16-lead TSSOP has a typical junction-to-ambient thermal resistance (θ_JA) of 150 °C/W, as specified in the "Thermal Information" table on page 3 of FN3284 Rev 11.00. This value assumes mounting on a standard high-thermal-conductivity test board in free air. For sustained 30 mA continuous current operation, junction temperature rise remains within safe limits (<150 °C) up to ~75 °C ambient with proper PCB copper area.
