Analog Devices Inc./Maxim Integrated MAX97001EVKIT+

Overview

MAX97001EVKIT+ from Maxim Integrated is an evaluation kit for the MAX97001 mono audio subsystem IC, featuring a 700mW Class D speaker amplifier and dual-channel Class H headphone amplifier with I²C control, integrated distortion limiter, and analog DPST switch. It supports 2.7V–5.5V speaker supply and 1.6V–2V headphone supply, and targets space-constrained portable audio applications including smartphones and multimedia players.

For engineers reviewing the MAX97001EVKIT+ datasheet, MAX97001EVKIT+ pinout, MAX97001EVKIT+ application, or MAX97001EVKIT+ equivalent, this kit enables rapid validation of audio signal routing, volume control, click-and-pop suppression, Class H charge-pump behavior, and I²C register configuration in real-world battery-powered systems.

Technical Context

The MAX97001EVKIT+ implements the full functional block diagram of the MAX97001 IC, including independent preamp gain (–6dB to +18dB), stereo single-ended/mono differential input selection, and dual-mixer architecture feeding both speaker and headphone paths. It validates the integrated 2-wire I²C interface (up to 400kHz) and supports all register-controlled features: distortion limiter attack/release timing, charge-pump mode transitions (invert/split), and HP/SPK on/off/volume states.

This kit demonstrates the MAX97001's ultra-low EMI filterless Class D output stage and ground-referenced DirectDrive® headphone outputs-eliminating coupling capacitors-and verifies operation across the –40°C to +85°C industrial temperature range using the 2mm × 2.5mm, 20-bump WLP package layout.

FAQ

What is the primary function of the MAX97001EVKIT+?

The MAX97001EVKIT+ is an evaluation kit designed exclusively to prototype, validate, and characterize the MAX97001 mono audio subsystem IC. It provides complete hardware access-including test points, jumpers, and I²C interface-to verify speaker amplifier performance (700mW Class D), headphone amplifier behavior (37mW/channel Class H), distortion limiting, and analog switch functionality under real operating conditions.

Does the MAX97001EVKIT+ include the MAX97001 IC pre-installed?

Yes, the MAX97001EVKIT+ ships with the MAX97001 IC (20-bump WLP package) fully assembled and soldered onto the board. No additional IC purchase or placement is required to begin evaluation. The kit also includes all necessary passive components-bypass capacitors, bias network, and optional ferrite bead-for immediate power-up and signal testing.

Can the MAX97001EVKIT+ be used to evaluate both speaker and headphone amplifier sections simultaneously?

Yes, the MAX97001EVKIT+ supports concurrent operation of the Class D speaker amplifier and stereo Class H headphone amplifier. Its layout provides independent power rails (PVDD and VDD), separate input routing, and isolated output test points (OUTP/OUTN and HPL/HPR), enabling simultaneous measurement of THD+N, SNR, efficiency, and inter-channel crosstalk per the MAX97001 datasheet specifications.

What I²C configuration options does the MAX97001EVKIT+ support?

The MAX97001EVKIT+ supports standard-mode I²C communication (up to 400kHz) with configurable pull-up resistors and direct SDA/SCL access via header pins. It validates all MAX97001 register functions-including volume control (SPKVOL, HPLVOL, HPRVOL), mixer routing (HPLMIX, HPRMIX, SPKMIX), distortion limiter enable (LMTEN), and charge-pump mode control-using the documented slave address and register map.

Is the MAX97001EVKIT+ RoHS-compliant and lead-free?

Yes, the MAX97001EVKIT+ is RoHS-compliant and lead-free, as indicated by the "+" suffix in its part number. All components-including the MAX97001 IC (MAX97001EWP+), passives, and PCB finish-meet EU Directive 2011/65/EU requirements and are suitable for commercial and industrial production environments requiring environmental compliance.
