MAX538BCSA+T

Digital To Analog Converters Overview

The MAX538BCSA+T is a low-power, voltage-output, 12-bit digital-to-analog converter (DAC) from the Maxim Integrated MAX538 series. It operates on a single +5V supply with a voltage range of 4.5V to 5.5V. The device features a buffered voltage output with a fixed gain of +1 and draws only 140µA of supply current. It utilizes a flexible 3-wire serial interface compatible with SPI, QSPI, and Microwire standards. Key performance metrics include a settling time of 25µs, an integral nonlinearity (INL) of ±0.5 LSB maximum, and a differential nonlinearity (DNL) of ±1 LSB. The component is housed in an 8-pin SOIC package and supports an operating temperature range of 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Low-power operation with 140µA supply current consumption

• Battery-operated or remote industrial controls
• Machine and motion control devices
• Cellular telephones

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CSA' corresponds to the 8-pin SOIC package and commercial temperature grade (0°C to +70°C). Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the ordering code matches the exact pinout and electrical specifications required for the target application design.

Digital To Analog Converters Selection Notes

Select this component when a single-supply 12-bit DAC with low power consumption is required. The MAX538 offers a fixed +1 gain buffer, distinguishing it from the MAX539 (+2 gain) and MAX531 (configurable gain/internal reference). Consider the 25µs settling time and serial interface speed limitations when designing high-speed data acquisition systems.

Digital To Analog Converters Part Context

The MAX538 belongs to the MAX531/MAX538/MAX539 family of low-power, voltage-output DACs. While sharing similar architecture and pinouts, the MAX538 is specifically configured with a fixed +1 gain buffer and lacks the internal reference found in the MAX531. It serves as a cost-effective solution for applications requiring precise analog voltage generation from digital inputs without external buffering components.

Digital To Analog Converters Replacement Considerations

The MAX539 is a functional alternative within the same family but provides a fixed +2 gain buffer instead of +1. Designers must verify that the system can accommodate the doubled output voltage range or adjust the reference input accordingly. Other family members like the MAX531 offer configurable gain but require additional external components.
