MAX6956AAX+

Display Drivers Overview

The MAX6956AAX+ is a 2-wire-interfaced LED display driver manufactured by Analog Devices Inc./Maxim Integrated. It supports up to 7 digits and 28 segments, featuring 20 output ports with low-level sink current capability of 18 mA. The device operates within a supply voltage range of 2.5 V to 5.5 V and consumes a maximum supply current of 230 uA. It is housed in an SSOP-36 package designed for surface-mount installation. The component functions reliably across an extended temperature range from -40°C to +125°C, with a power dissipation rating of 941 mW.

Display Drivers Procurement Notes

Verify the specific suffix 'AAX+' against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for SSOP-36 components. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit sources. Confirm RoHS compliance status if required by project specifications. Validate electrical parameters against the latest datasheet revision before finalizing procurement orders.

Display Drivers Selection Notes

Select this component when a 2-wire interface is preferred over SPI or I2C for display driving. Consider the 18 mA sink current capability for direct LED connection without external transistors. Evaluate the SSOP-36 package size constraints against available board space. Check the operating temperature range requirements against the -40°C to +125°C specification. Compare power consumption needs with the 230 uA maximum supply current rating.

Display Drivers Part Context

The MAX6956 series includes variants like MAX6956AAI+ and MAX6956ANI+, differing primarily in package types such as SSOP and PDIP. These drivers are part of Maxim's LED display solution portfolio, offering constant current outputs. The AAX+ variant specifically denotes the SSOP-36 surface-mount configuration. Related parts include the MAX6957 and MAX6958, which offer different segment counts and pin configurations.
