MAX5250BCPP+

Digital To Analog Converters Overview

The MAX5250BCPP+ is a low-power, quad, 10-bit voltage-output digital-to-analog converter (DAC) with serial interface. It integrates four DACs and precision output amplifiers in a 20-pin Plastic DIP package. Operating on a single +5V supply, it features a 3-wire serial interface compatible with SPI/QSPI and MICROWIRE. Key electrical parameters include a typical settling time of 10µs to ±1/2LSB, a supply current of 0.85mA in normal operation, and 10µA in shutdown mode. The device guarantees monotonicity with DNL of ±1 LSB and INL of ±1 LSB.

Digital To Analog Converters Feature Summary

• Integrates four 10-bit DACs with configurable output amplifiers for flexible gain settings.
• Supports simultaneous or independent control of all channels via a 3-wire serial interface.
• Features software shutdown reducing supply current to 10µA and hardware shutdown lockout.
• Includes an active-low reset that clears all registers and DAC outputs to zero.

Digital To Analog Converters Applications

• Digital offset and gain adjustment circuits
• Microprocessor-controlled industrial systems
• Industrial process control instrumentation
• Automatic test equipment (ATE)
• Remote industrial control interfaces

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CPP+' indicates the 20-pin Plastic DIP package and commercial temperature range (0°C to +70°C). Confirm the 'B' grade specifies the integral nonlinearity (INL) performance level as defined in the ordering information table. Ensure compatibility with existing PCB footprints for through-hole mounting. Check for RoHS compliance status as indicated in official documentation.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel DAC solution is required with buffered outputs. The MAX5250 offers access to amplifier feedback pins for custom gain configurations. Compare against the MAX525 series if 12-bit resolution is needed. Consider the MAX5251 if lower voltage operation (3V) is required. Verify that the 10-bit resolution and 10µs settling time meet system speed and accuracy requirements.

Digital To Analog Converters Part Context

The MAX5250 belongs to the Maxim Integrated family of low-power, multi-channel DACs. It is designed for applications requiring multiple analog outputs from a single controller. The device simplifies system design by integrating reference inputs, output buffers, and serial logic into a compact package. It serves as a bridge between digital control systems and analog actuators or signal conditioning stages.

Digital To Analog Converters Replacement Considerations

The MAX525ACPP+ is a pin-compatible alternative with improved INL specifications (±1/2 LSB vs ±1 LSB). The MAX5250AEPP+ offers an extended temperature range (-40°C to +85°C). Both alternatives maintain the same functional interface and package type but differ in accuracy and operating temperature limits.

Digital To Analog Converters FAQ

How are the output amplifiers configured for gain adjustment?

Each amplifier's negative input (FB_ pin) is available to the user, allowing external resistors to set specific gain configurations, remote sensing, or high output drive capacity beyond unity gain.

Can the MAX5250 be daisy-chained with other devices?

Yes, multiple MAX5250s can be daisy-chained by connecting the DOUT pin of one device to the DIN pin of the next, allowing data verification and cascaded control.

What happens to the outputs during power-on reset?

An active-low reset (CL pin) or power-up event clears all input and DAC registers to zero, setting all DAC outputs to 0V and the user-programmable output (UPO) to low.
