Analog Devices Inc. ADG1606BRUZ

Overview

ADG1606BRUZ from Analog Devices is a 16-channel single-ended analog multiplexer with 4.5 Ω typical on resistance, ±5 V dual or +12 V single supply operation, rail-to-rail signal handling, and 3 V logic-compatible control inputs. It routes one of 16 source inputs to a common drain (D) under 4-bit binary address (A0–A3) and active-high enable (EN), serving data acquisition systems requiring low distortion and high channel count.

For engineers reviewing the ADG1606BRUZ datasheet, ADG1606BRUZ pinout, ADG1606BRUZ application, or ADG1606BRUZ equivalent, key selection criteria include on-resistance flatness (1.1 Ω typ), THD+N (0.04% typ), continuous current per channel (up to 378 mA in LFCSP at 12 V), break-before-make timing (42 ns typ), and compatibility with industrial temperature range (−40°C to +125°C).

Technical Context

The ADG1606BRUZ implements a 1-of-16 decoder architecture with four address lines (A0–A3) and an enable input (EN) to select and activate exactly one of sixteen bidirectional analog channels. All switches conduct equally well in both directions and support rail-to-rail analog signals across the full supply range.

iCMOS® process technology enables ultralow power dissipation (IDD ≤ 1.0 µA max) while maintaining robust performance: on-resistance flatness remains ≤2 Ω over temperature and signal swing, and leakage currents stay below ±25 nA across −40°C to +125°C.

Key Specifications

Pinout & Package

FAQ

What supply configurations does the ADG1606BRUZ support?

The ADG1606BRUZ operates from ±3.3 V to ±8 V dual supplies or 3.3 V to 16 V single supplies. It supports rail-to-rail analog signal swings across the full supply range, with no VL logic supply required. At ±5 V, typical on resistance is 4.5 Ω; at 12 V single supply, it drops to 4 Ω. The ADG1606BRUZ maintains specified performance across −40°C to +125°C in both configurations.

How does the ADG1606BRUZ handle channel switching timing?

The ADG1606BRUZ features a guaranteed break-before-make delay of 15 ns minimum and 42 ns typical, preventing momentary shorts during channel transitions. Turn-on time (tON) is 132 ns typical at ±5 V, and turn-off time (tOFF) is 124 ns typical. These values scale predictably with supply voltage - e.g., tON reduces to 108 ns at 12 V - enabling precise timing control in high-speed multiplexed systems using the ADG1606BRUZ.

What is the maximum continuous current per channel for the ADG1606BRUZ?

The ADG1606BRUZ supports up to 378 mA continuous current per channel when packaged in the 32-lead LFCSP and operated at 12 V single supply (TJ ≤ 125°C). In the 28-lead TSSOP package, the limit is 273 mA under identical conditions. Derating applies at elevated temperatures and lower supplies - e.g., 164 mA at 3.3 V/25°C in TSSOP. These ratings are validated per Table 5 in the ADG1606BRUZ datasheet.

Does the ADG1606BRUZ require external level-shifting for 3.3 V logic control?

No, the ADG1606BRUZ does not require external level-shifting. Its digital inputs are 3 V logic-compatible, with VINH ≥ 2.0 V and VINL ≤ 0.8 V - fully compatible with standard 3.3 V CMOS outputs. The device accepts control signals directly from microcontrollers, FPGAs, and ASICs without additional circuitry, simplifying interface design and reducing board area in systems using the ADG1606BRUZ.

What thermal considerations apply to the ADG1606BRUZ in high-current operation?

The ADG1606BRUZ thermal resistance depends on package: θJA = 97.9°C/W for TSSOP and 46°C/W for LFCSP. At 378 mA and 12 V, power dissipation per channel is ~4.5 W - requiring careful thermal design. Use the exposed pad (soldered to VSS plane) and minimize trace resistance. Derate current above 85°C ambient per Table 5. The ADG1606BRUZ junction temperature must remain ≤150°C; thermal simulation and IR imaging are recommended for high-density layouts.
