Product details
Overview
ADG1407BRUZ from Analog Devices is a monolithic iCMOS® 8-channel differential 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. It supports ±15 V / +12 V / ±5 V supplies, delivers up to 235 mA continuous current per channel in LFCSP package, and targets precision data acquisition and audio routing where low distortion and high channel isolation are critical.
For engineers reviewing the ADG1407BRUZ datasheet, ADG1407BRUZ pinout, ADG1407BRUZ application, or ADG1407BRUZ equivalent, key selection considerations include its differential 1-of-8 switching architecture, 110 MHz −3 dB bandwidth at ±15 V, ultralow 10 pC charge injection, and compatibility with 3 V logic inputs across industrial temperature range (−40°C to +125°C).
Technical Context
The ADG1407BRUZ implements a 3-bit binary decoder (A0–A2) controlling eight differential switch pairs (S1A/S1B through S8A/S8B), with active-high EN enabling full device shutdown. Its iCMOS process enables 33 V absolute maximum rating while maintaining low power dissipation and compact 5 mm × 5 mm LFCSP footprint.
Switching behavior is strictly break-before-make, ensuring no momentary short between channels. Signal path performance is characterized by <1.7 Ω on-resistance match (ΔRON) and 2.3 Ω max on-resistance flatness (RFLAT(ON)) over full temperature range, supporting high-fidelity signal routing without gain error or distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance (RON) | 9.5 Ω typ at ±15 V, 25°C - enables low insertion loss and minimal voltage drop in precision signal paths. |
| −3 dB Bandwidth | 110 MHz typ at ±15 V - supports high-speed analog multiplexing up to video and wideband instrumentation frequencies. |
| Charge Injection | 10 pC typ - minimizes sampling errors in data acquisition and sample-and-hold systems. |
| Off Isolation | −73 dB typ at 1 MHz - ensures strong channel-to-channel rejection in multi-signal routing applications. |
| Supply Range | ±4.5 V to ±16.5 V dual or +5 V to +16.5 V single - provides design flexibility across industrial, medical, and test equipment rails. |
| Logic Compatibility | 3 V input compatible with TTL/CMOS - simplifies interface to microcontrollers and FPGAs without level-shifting. |
| Continuous Current | 235 mA max per channel (LFCSP, ±15 V, 25°C) - supports driving moderate loads such as op-amp inputs or ADC drivers. |
Pinout & Package
The ADG1407BRUZ is available in a 32-lead, 5 mm × 5 mm LFCSP package with exposed pad tied to VSS. Pin count and layout are identical across variants; BRUZ suffix denotes LFCSP package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 29) | Positive supply rail | Accepts +5 V to +16.5 V; must be decoupled for noise-sensitive analog operation. |
| VSS (Pin 25) | Negative supply rail | Accepts −5 V to −16.5 V; exposed pad must be connected to VSS for thermal and electrical integrity. |
| DA / DB (Pins 27 / 31) | Differential drain outputs | Common output pair; bidirectional signal path with rail-to-rail swing capability. |
| S1A–S8A / S1B–S8B (Pins 17–24, 1–8) | Differential source inputs | Eight matched differential input pairs; each pair connects to DA/DB when selected. |
| A0–A2 (Pins 15–10) | Binary address inputs | 3-bit code selects one of eight differential channels; logic thresholds fixed at 0.8 V / 2.0 V. |
| EN (Pin 16) | Enable control | Active-high; drives all switches off when low, eliminating leakage and crosstalk during standby. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1207BRUZ | Higher on resistance (120 Ω typ), lower bandwidth (25 MHz), but lower charge injection (0.2 pC) and leakage (0.01 pA typ). | Better suited for ultra-low-leakage sample-and-hold or high-impedance sensor buffering where speed is secondary. | Select ADG1207BRUZ only when sub-pA leakage dominates over bandwidth and on-resistance requirements. |
| MAX4687ETE+ | Single-supply only (2.7 V to 5.5 V), 3.5 Ω RON, but no differential architecture - requires external balun for differential use. | Applicable in low-voltage portable systems where differential signaling is not mandatory and cost is constrained. | Choose MAX4687ETE+ only for 3.3 V/5 V single-ended designs; not a functional substitute for true differential routing. |
Compared with ADG1207BRUZ and MAX4687ETE+, the ADG1407BRUZ uniquely combines high-voltage differential switching, 110 MHz bandwidth, and 9.5 Ω RON - making it the only option among the three capable of replacing discrete relay-based multiplexers in ±15 V medical and ATE signal chains without performance compromise.

FAQ
What supply voltages does the ADG1407BRUZ support?
The ADG1407BRUZ operates from ±4.5 V to ±16.5 V dual supplies or +5 V to +16.5 V single supply. It is fully specified at ±15 V, +12 V, and ±5 V conditions, with rail-to-rail analog signal handling across the full supply range. Absolute maximum ratings allow VDD–VSS up to 35 V, but functional operation is guaranteed only within the specified ranges documented in the ADG1407BRUZ datasheet Rev. C.
Does the ADG1407BRUZ support differential signaling natively?
Yes, the ADG1407BRUZ is a true differential 1-of-8 analog multiplexer with dedicated SxA/SxB input pairs and DA/DB differential outputs. Each selected channel routes a fully differential signal path with matched on-resistance and timing - no external components are needed to preserve common-mode rejection. This native differential architecture distinguishes it from single-ended multiplexers like the ADG1406BRUZ.
What is the maximum continuous current per channel for ADG1407BRUZ in LFCSP package?
At ±15 V dual supply and 25°C ambient, the ADG1407BRUZ in 32-lead LFCSP supports up to 235 mA continuous current per differential channel. Derating applies at higher temperatures: 125 mA at +85°C and 55 mA at +125°C. These values are confirmed in Table 6 of the ADG1407BRUZ datasheet and assume proper PCB thermal management with the exposed pad soldered to VSS.
How does the break-before-make timing work on ADG1407BRUZ?
The ADG1407BRUZ guarantees break-before-make operation with a minimum tBBM of 10 ns at ±15 V (typical 40 ns). This ensures that the previously selected channel disconnects completely before the newly addressed channel connects - preventing momentary shorts between differential sources. The timing is independent of logic slew rate and is verified across voltage and temperature ranges per Figure 31 in the ADG1407BRUZ datasheet.
Is the ADG1407BRUZ pin-compatible with ADG1406BRUZ?
No, the ADG1407BRUZ and ADG1406BRUZ are not pin-compatible. The ADG1406BRUZ is a 16-channel single-ended multiplexer with 28-pin TSSOP or 32-pin LFCSP pinout featuring S1–S16 and D pins. The ADG1407BRUZ uses a different pin mapping optimized for differential operation (S1A/S1B–S8A/S8B, DA/DB), with distinct address line count (3-bit vs. 4-bit) and no direct physical or logical pin correspondence.
