MAX534BEEE+

Digital To Analog Converters Overview

The MAX534BEEE+ is a low-power, quad 8-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +4.5V to +5.5V supply and features rail-to-rail buffered voltage outputs. The device includes a double-buffered serial interface compatible with SPI, QSPI, and Microwire protocols, supporting clock frequencies up to 10MHz. Key electrical specifications include an integral nonlinearity (INL) of ±2 LSB and differential nonlinearity (DNL) of ±1 LSB for the B-grade variant. Supply current is typically 0.8mA during operation and drops to 2.5µA in shutdown mode. The component is housed in a 16-pin QSOP package and is rated for an operating temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify that the ordering suffix 'EEE' corresponds to the specific 16-pin QSOP package and the industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status (+ suffix) and ensure the supplier provides the official datasheet for the MAX534 series to validate pinout and timing characteristics before integration.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel DAC with low power dissipation and rail-to-rail output swing is required. Ensure the system operates within the +4.5V to +5.5V supply range. Verify that the 8-bit resolution meets the application's accuracy requirements and that the serial interface timing aligns with the microprocessor capabilities.

Digital To Analog Converters Part Context

The MAX534BEEE+ belongs to the MAX534 family of low-power, quad 8-bit DACs. This family offers various package options including Plastic DIP and CERDIP, with different temperature grades designated by suffixes such as 'C' for commercial and 'E' for industrial ranges. The B-grade indicates specific linearity performance limits compared to the A-grade.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same package and specification include the MAX534BEPE+ (Plastic DIP) or other MAX534 variants with matching temperature ratings. Cross-referencing pinouts and electrical parameters is essential when considering alternative manufacturers.

Digital To Analog Converters FAQ

What is the maximum serial clock frequency supported by the MAX534?

The serial clock (SCLK) can be driven at rates up to 10MHz.

How does the MAX534 handle simultaneous updates of all DAC channels?

Simultaneous updates can be achieved using the asynchronous LDAC pin or via the software 'LDAC' command, which transfers contents from input latches to DAC latches.

Can multiple MAX534 devices be connected in a chain?

Yes, any number of MAX534s can be daisy-chained by connecting the DOUT of one device to the DIN of the next, utilizing the NOP instruction to pass data through intermediate devices.
