Analog Devices Inc./Maxim Integrated MAX14811CTN+

MAX14811 converts CMOS-compatible logic commands into two independently controlled high-voltage pulser channels. Each channel has positive and negative pulser paths, active-clamp control and its own enable input. The device is intended for applications that need fast, controlled pulses into capacitive loads, including ultrasound and industrial imaging equipment.

The manufacturer's ordering table specifies 56 TQFN-EP, package code T5677+1, outline 21-0144 and land pattern 90-0042. The existing LCDChip product and package registry say 56-WFQFN Exposed Pad. Both descriptions identify a 56-pin exposed-pad QFN family, but mechanical equivalence must be checked from the controlled package drawing before PCB release.

Layout checks

• Compare land pattern 90-0042 with the catalog footprint.
• Connect the exposed pad to VSS as directed in the data sheet.
• Place low-inductance supply bypass and external coupling capacitors close to the device.

The registered JPG is absent locally and returns HTTP 404 on the production site. This draft must not be published until the picture and package match are verified.

The following named signal groups and examples follow the manufacturer's pin-description and top-view tables. Underscore denotes channel 1 or 2; consult the full 56-pin table for every pad.

Example channel-1 pins: CGP1 pin 1, VPP1 pins 2 and 3, OP1 pin 5, OCP1 pin 6, OCN1 pin 8, ON1 pin 9, VNN1 pins 11 and 12. Use the complete manufacturer's table for final routing.

Typical drive-current and impedance figures are not guaranteed limits. Use the data-sheet electrical-characteristics conditions, power-dissipation equations and safe operating limits for design calculations.

The manufacturer identifies other high-voltage pulser families, but differing channel counts, output stages, package drawings, protection behavior and control truth tables prevent an assumed drop-in substitution. Confirm exact supply rails, logic timing, pulser and clamp outputs, exposed-pad connection and temperature grade. No LCDChip internal alternative is linked because no exact candidate was validated through the production product API.

MAX14811CTN+ is documented by Analog Devices under the Maxim Integrated MAX14811 Rev. 0 data sheet. The plus suffix denotes a lead-free/RoHS-compliant package in the manufacturer ordering table. Check current manufacturer lifecycle and product-change notices before approving new procurement.

Verify the complete order code, package marking and traceability documents against approved sourcing records. Inspect exposed-pad soldering, moisture handling and storage requirements. This component operates at hazardous voltages; application-level safety and qualification remain the system designer's responsibility.

Observe high-voltage handling precautions. Consult the current manufacturer data sheet for truth tables, power-supply sequencing, coupling-capacitor values, thermal calculations, pin placement and the controlled 56-pin TQFN-EP drawing. Confirm the catalog footprint and add a verified package JPG before publishing this page.
