Analog Devices Inc. ADG1406BRUZ

Overview

ADG1406BRUZ from Analog Devices is a 16-channel single-ended analog multiplexer with 9.5 Ω typical on-resistance at ±15 V, rail-to-rail signal handling (VSS to VDD), and break-before-make switching action. It operates across ±15 V, +12 V, or ±5 V supplies, supports 3 V logic-compatible digital inputs, and delivers ≤10 pC charge injection - ideal for precision data acquisition and medical instrumentation requiring low distortion and high channel isolation.

For engineers reviewing the ADG1406BRUZ datasheet, ADG1406BRUZ pinout, ADG1406BRUZ application, or ADG1406BRUZ equivalent, this page provides verified specifications including on-resistance flatness (1.6 Ω typ), −73 dB off isolation at 1 MHz, THD+N of 0.07% (15 V, 20 Hz–20 kHz), 60 MHz −3 dB bandwidth, and continuous current capability up to 300 mA in LFCSP package.

Technical Context

The ADG1406BRUZ implements a 4-bit binary decoder (A0–A3) controlling one-of-16 channel selection between 16 source pins (S1–S16) and a common drain (D). Its iCMOS® process enables 33 V absolute maximum rating while maintaining ultralow leakage (±0.01 nA typ off-leakage) and low power consumption (280 μA max IDD at 5 V logic).

Break-before-make timing (40 ns typ) prevents momentary shorting during channel transitions. Rail-to-rail operation ensures full analog swing across supply rails, and 3 V logic compatibility allows direct interfacing with modern microcontrollers without level shifting.

Key Specifications

Pinout & Package

ADG1406BRUZ is available in 28-lead TSSOP (RU-28) and 32-lead 5 mm × 5 mm LFCSP (BRUZ) packages. The BRUZ variant uses an exposed pad tied to VSS for thermal and electrical stability.

FAQ

What supply voltages does the ADG1406BRUZ support?

The ADG1406BRUZ operates across ±15 V, +12 V, or ±5 V supplies. Absolute maximum ratings allow VDD to VSS up to 35 V, with specified performance at ±15 V (±13.5 V min), +12 V (10.8 V min), and ±5 V (±4.5 V min). The device maintains rail-to-rail analog signal range (VSS to VDD) across all supported configurations, and its iCMOS® process ensures stable operation without latch-up under transient overvoltage conditions.

Does the ADG1406BRUZ support 3 V logic inputs?

Yes, the ADG1406BRUZ accepts 3 V logic-level digital inputs: VINH is guaranteed ≥2.0 V and VINL ≤0.8 V, allowing direct interface with 3.3 V microcontrollers, FPGAs, and DSPs without level-shifting circuitry. Input current remains below ±0.1 μA across temperature, minimizing loading on driving logic. This feature simplifies system design in mixed-voltage environments such as portable medical devices with 3.3 V control planes and ±15 V analog signal chains.

What is the maximum continuous current per channel for ADG1406BRUZ?

In the BRUZ (32-lead LFCSP) package, the ADG1406BRUZ supports up to 300 mA continuous current per channel at 25°C with ±15 V supplies. Derating applies with temperature: 150 mA at +85°C and 60 mA at +125°C. At +12 V single supply, the rating is 260 mA (25°C), and at ±5 V, it is 245 mA (25°C). These values are validated per Table 5 in the datasheet and reflect the thermal advantage of the exposed-pad LFCSP construction.

How does the break-before-make timing affect system design with ADG1406BRUZ?

The ADG1406BRUZ guarantees a minimum break-before-make time delay (tBBM) of 10 ns and typical value of 40 ns under ±15 V conditions. This prevents momentary short-circuits between channels during switching - critical in applications like motor phase current sensing or relay replacement where simultaneous conduction could cause shoot-through faults. Designers must ensure address settling time exceeds tBBM; no external delay circuitry is needed due to built-in timing control.

Is ADG1406BRUZ pin-compatible with other devices in the ADG14xx family?

No - the ADG1406BRUZ is not pin-compatible with ADG1407 or ADG1408. While all share the same LFCSP-32 and TSSOP-28 footprints, pin functions differ significantly: ADG1406BRUZ has 16 Sx pins and one D pin, whereas ADG1407 has differential SxA/SxB and DA/DB pairs. The A0–A3 and EN assignments also differ (ADG1407 uses only A0–A2). Board layout must be specific to ADG1406BRUZ; swapping requires schematic and layout revision.
