MAX534BCPE+

Digital To Analog Converters Overview

The MAX534BCPE+ is an 8-bit quad 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 output buffers. The device includes a double-buffered serial interface compatible with SPI, QSPI, and Microwire protocols. Electrical specifications include a typical settling time of 8µs, a maximum integral nonlinearity (INL) of ±2 LSB, and a maximum differential nonlinearity (DNL) of ±1 LSB. Supply current is 0.8mA during operation and reduces to 2.5µA in shutdown mode. The component is housed in a 16-pin Plastic DIP package and supports an operating temperature range of 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Features ultra-low power consumption with a dedicated software shutdown mode.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BCPE+' against the manufacturer's official datasheet to confirm the commercial temperature grade and plastic DIP packaging. Ensure that the ordering documentation matches the required electrical tolerances for INL and DNL specified for this variant. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a low-power, quad-channel DAC with rail-to-rail output capability is required within a single-supply system. Verify that the 8-bit resolution meets the application's accuracy needs and that the serial interface timing aligns with the host microprocessor's clock speeds. Consider the thermal dissipation limits associated with the PDIP package if multiple channels are driven near full scale.

Digital To Analog Converters Part Context

This part belongs to the MAX534 family of low-power, 8-bit quad DACs. The BCPE+ designation specifically indicates the commercial temperature range variant packaged in a 16-pin plastic dual in-line format. Other variants in the series offer extended temperature ranges or different package types such as QSOP.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same package and specification profile include the MAX534ACPE+ and MAX534BEPE+. These alternatives share identical pinouts and functional characteristics but differ in their guaranteed linearity performance metrics and operating temperature ranges.

Digital To Analog Converters FAQ

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

Simultaneous updates can be achieved using the asynchronous LDAC pin or by issuing a software command that loads all DAC registers from their respective input registers at the rising edge of the CS signal.

What is the function of the UPO pin?

The User-Programmable Output (UPO) pin acts as a logic output that can be controlled via software commands, allowing it to function as a microcontroller I/O extender for controlling external devices across isolated interfaces.

Can the MAX534 be used in a daisy-chain configuration?

Yes, multiple MAX534 devices can be daisy-chained by connecting the DOUT pin of one device to the DIN pin of the next. The No Operation (NOP) command allows data to pass through intermediate devices without altering their state.
