Analog Devices Inc./Maxim Integrated MAX14511EEVB+

Overview

MAX14511EEVB+ from Maxim Integrated is a USB 2.0 Hi-Speed and audio DPDT switch evaluation board supporting dual-path signal routing for USB (480Mbps) and AC-coupled analog signals, featuring VBUS detection (VB), +5.5V COM fault protection, and operation from +2.7V to +5.0V. It enables automatic USB/audio path selection in portable devices with low 12μA supply current, 2.4Ω typical on-resistance, and 950MHz -3dB bandwidth.

For engineers reviewing the MAX14511EEVB+ datasheet, MAX14511EEVB+ pinout, MAX14511EEVB+ application, or MAX14511EEVB+ equivalent, this page delivers verified functional context, validated package mapping, confirmed switching performance metrics, and precise alternative part comparisons - all grounded in Maxim's official documentation for MAX14511E device-level specifications and EVB design intent.

Technical Context

The MAX14511EEVB+ implements a single DPDT analog switch architecture based on the MAX14511E IC, configured to demonstrate VBUS-triggered automatic path selection between USB (UNC1/UNC2) and audio (ANO1/ANO2) channels. Its control logic relies on VB input threshold (VCC + 0.2V to VCC + 1.0V) and AOR override functionality, with fault protection active on COM1/COM2 up to +5.5V.

This evaluation board supports bidirectional signal routing with negative swing capability (down to VCC − 5.0V on ANO_ paths), 0.05% THD+N at 20Hz–20kHz, and <5µs turn-off time. It validates the IC's USB 2.0 compliance, ESD robustness (±15kV HBM on COM pins), and low RON flatness (20mΩ typ) under real-world layout constraints.

FAQ

What is the primary function of the MAX14511EEVB+?

The MAX14511EEVB+ is an evaluation board for the MAX14511E DPDT analog switch IC. It demonstrates automatic USB/audio path selection using VBUS detection (VB input), supports Hi-Speed USB (480Mbps) and AC-coupled audio signals, and validates the IC's +5.5V COM fault protection, 950MHz bandwidth, and negative-swing capability (VCC − 5.0V). The MAX14511EEVB+ enables rapid prototyping of dual-mode interface designs in portable electronics.

Does the MAX14511EEVB+ support both USB and audio signal routing simultaneously?

No - the MAX14511EEVB+ implements a DPDT switch that routes either USB or audio signals per channel, not both simultaneously. When VBUS is detected (VB ≥ VCC + 0.2V), the MAX14511EEVB+ configures the MAX14511E to connect COM1/COM2 to UNC1/UNC2 (USB path); otherwise, it connects to ANO1/ANO2 (audio path). This automatic selection prevents signal contention and ensures proper mode isolation as specified in the MAX14511E truth table.

What are the key electrical characteristics validated by the MAX14511EEVB+?

The MAX14511EEVB+ validates core MAX14511E parameters including 2.4Ω typical on-resistance (ensuring low insertion loss), 950MHz -3dB bandwidth (supporting USB 2.0 eye compliance), 0.05% THD+N (critical for high-fidelity audio), <5µs turn-off time (enabling fast mode switching), and +5.5V fault protection on COM1/COM2 (meeting USB 2.0 robustness requirements). These are measured per Maxim's test circuits in the MAX14511E datasheet.

How does the VBUS detection feature work on the MAX14511EEVB+?

On the MAX14511EEVB+, the VB input monitors host-side VBUS presence. When VB voltage exceeds the threshold (VCC + 0.2V to VCC + 1.0V), the MAX14511E IC automatically connects COM1/COM2 to UNC1/UNC2 for USB signaling. If VB falls below threshold or AOR is driven high, routing switches to ANO1/ANO2 for audio. This eliminates external microcontroller intervention for mode selection - a key design advantage validated by the MAX14511EEVB+.

Is the MAX14511EEVB+ compatible with other devices in the MAX14508E–MAX14511E family?

The MAX14511EEVB+ is specifically optimized for the MAX14511E IC and shares the same 10-pin UTQFN footprint and pinout as MAX14510E, but differs from MAX14508E/MAX14509E due to control logic (VB/AOR vs. EN/CB). While physical mounting may be similar, firmware and signal routing must align with MAX14511E's VBUS-detection behavior. The MAX14511EEVB+ cannot substitute for MAX14508EEVB+ or MAX14509EEVB+ without hardware and control logic revision.
