MAX14815ETK+

Overview

The MAX14815ETK+ is a highly integrated, octal five-level high-voltage ultrasound transmitter (pulser) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It generates high-frequency high-voltage bipolar pulses designed to drive piezoelectric sensors in ultrasound systems via two pairs of independent high-voltage power supplies. The component is housed in a 68-TQFN package measuring 10x10 mm and is classified as specialized Power Management IC (PMIC).

Feature Summary

• Generates high-frequency high-voltage bipolar pulses for ultrasound applications
• Octal channel architecture supporting eight independent outputs
• Five-level pulse generation capability
• Integrated design driving piezoelectric sensors via dual independent high-voltage supply pairs

Applications

• Ultrasound system transducer driving
• Medical imaging equipment pulse generation
• High-voltage sensor actuation circuits

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability upon receipt. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the official datasheet to prevent package damage prior to soldering.

Selection Notes

Select this component for designs requiring integrated multi-channel high-voltage pulsing without external discrete driver stages. Evaluate thermal performance within the 10x10mm TQFN footprint against system power dissipation limits. Ensure the host control interface supports the required digital pulser configuration commands for precise pulse timing and amplitude control.

Part Context

This device belongs to the MAX148xx series of specialized PMICs focused on ultrasound front-end electronics. It complements other Maxim Integrated solutions like the MAX14808 and MAX14809, which offer similar octal high-voltage digital pulser functionalities but may differ in specific integration levels or auxiliary power management features tailored for distinct ultrasound probe architectures.

Replacement Considerations

The MAX14808ETK+ and MAX14809ETK+ are documented members of the same functional family offering octal high-voltage digital pulsing capabilities. Verify pinout compatibility and specific electrical parameter alignment with the official datasheets before substitution.
