Product details

VFD driver with wide supply and serial control

The MAX6922AQH+TD from Analog Devices is a vacuum fluorescent (VF) display driver that takes a 4-wire serial input and drives the anodes and grids of a VFD tube. Its supply range of 8V to 76V covers the typical anode and filament bias voltages used in automotive dashboards, industrial panel meters, and appliance displays. The serial interface keeps the host MCU pin count low — three or four GPIOs are enough to control a multi-digit readout.

Supply current and temperature range

Quiescent supply current runs 1.65 mA, which is modest for a VFD driver and matters when the display is part of a battery-backed or thermally constrained assembly. The operating temperature range of -40°C to 125°C covers under-hood automotive, outdoor industrial terminals, and engine-compartment instrumentation — places where a standard commercial-grade driver would drift or latch up.

Lifecycle and sourcing

The MAX6922AQH+TD carries an active lifecycle status and is ROHS3 compliant. No last-time-buy or obsolescence notice is in effect, so it remains a viable choice for both new designs and production replenishment.

Frequently asked questions

What is the interface of the MAX6922AQH+TD?

The MAX6922AQH+TD uses a 4-wire serial interface to receive display data from a host microcontroller. This keeps the control wiring to four signals — typically data, clock, latch, and blank — and simplifies the PCB layout.

What is the difference between MAX6922AQH+TD and MAX6922AQH+T?

The difference is packaging and reel quantity. The MAX6922AQH+TD is supplied in Tape & Reel (TR) or Cut Tape (CT), while the MAX6922AQH+T is typically a different tape/reel option. Functionally the die is identical; the choice depends on your assembly line's feeder setup and volume.
