MAX5158EPE+

Digital To Analog Converters Overview

The MAX5158EPE+ is a low-power, dual, 10-bit voltage-output digital-to-analog converter (DAC) in a 16-pin Plastic DIP package. It operates from a single +5V supply with a typical quiescent current of 500µA and 2µA in shutdown mode. The device features an internal gain of +2V/V, rail-to-rail output swing, and an 8µs settling time. It supports SPI/QSPI and Microwire serial interfaces, includes double-buffered registers, and offers programmable logic and daisy-chaining capabilities.

Digital To Analog Converters Feature Summary

• Dual-channel 10-bit DAC architecture with integrated +2V/V gain amplifiers
• Rail-to-rail output swing capability for maximum dynamic range
• Double-buffered input structure allowing independent or simultaneous register updates
• Programmable shutdown mode reducing power consumption to 2µA

Digital To Analog Converters Applications

• Digital offset and gain adjustment circuits
• Microprocessor-controlled systems requiring precise analog control
• Motion control applications needing fast settling times
• Remote industrial control systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix EPE corresponds to the Plastic DIP package and the -40°C to +85°C operating temperature range as defined in the official ordering information. Confirm RoHS compliance status through the manufacturer's current documentation, as legacy parts may have varying environmental declarations. Ensure the source document explicitly lists this part number to avoid confusion with the QSOP variant or the MAX5159 model.

Digital To Analog Converters Selection Notes

Select the MAX5158EPE+ when a dual-channel solution with high precision and low power consumption is required in a through-hole package. The internal +2V/V gain simplifies circuit design by maximizing output swing relative to the reference voltage. Consider the 8µs settling time for applications requiring moderate speed. Verify that the serial interface compatibility matches the host controller's protocol requirements.

Digital To Analog Converters Part Context

This component belongs to the MAX5158/MAX5159 family of low-power, serial, voltage-output DACs manufactured by Analog Devices Inc./Maxim Integrated. The family distinguishes between the MAX5158 (+5V operation) and MAX5159 (+3V operation). The EPE suffix specifically denotes the Plastic DIP package option within this series, providing a through-hole alternative to the space-saving QSOP package.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitutes include other members of the MAX5158 family such as the MAX5158EEE (QSOP package) or MAX5158CPE (commercial temperature range). Direct replacements must match the 10-bit resolution, dual-channel configuration, and serial interface compatibility. Verify pinout and electrical characteristics against the target application requirements before substitution.

Digital To Analog Converters FAQ

How does the internal gain affect the output voltage range?

The internal resistors provide a fixed gain of +2V/V when the OS_ pins are connected to AGND. This doubles the output voltage swing relative to the reference input, maximizing dynamic range.

Can the DACs be updated independently?

Yes, the double-buffered input structure allows loading the input registers without updating the DAC registers, or updating them simultaneously. The serial interface commands determine which registers are affected.

What is the function of the PDL pin?

The Power-Down Lockout (PDL) pin disables the software shutdown feature when held low. Transitioning PDL from high to low can also asynchronously wake up the device from shutdown mode.
