MX7548TQ

Digital To Analog Converters Overview

The MX7548TQ is a CMOS, 12-bit Digital-to-Analog Converter (DAC) from the MX7548 series by Analog Devices Inc./Maxim Integrated. It features an R-2R resistor ladder architecture and provides a single unbuffered current output. The device utilizes a parallel interface for data input and requires an external reference voltage. It operates on dual power supplies ranging from 4.75 V to 5.25 V or 11.4 V to 15.75 V. Key electrical parameters include a settling time of 1 µs, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±1 LSB. The component functions within a commercial temperature range of 0°C to +70°C and is housed in a 20-TQFP package.

Digital To Analog Converters Feature Summary

• CMOS technology ensures low power consumption while maintaining high-speed performance.
• Compatible with standard microprocessor buses for simplified system integration.
• Provides precise analog output conversion with specified linearity accuracy.

Digital To Analog Converters Applications

• Industrial process control systems requiring precise signal generation.
• Programmable gain amplifiers and variable voltage references.
• Waveform generation circuits in test and measurement equipment.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'TQ' corresponds to the TQFP package variant when sourcing. Confirm RoHS compliance status as manufacturing practices may vary across production lots. Check for active obsolescence notices from Analog Devices regarding this specific part number before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select the MX7548TQ when a 12-bit resolution with 1 µs settling time is required in a surface-mount format. Ensure the design supports parallel data interfacing and external reference configurations. Compare against the MX7538 for higher 14-bit resolution needs or the MX7543 if serial interface compatibility is preferred over parallel throughput.

Digital To Analog Converters Part Context

The MX7548 belongs to the Maxim Integrated CMOS DAC family, designed for applications needing moderate resolution and speed. It serves as a bridge between digital control logic and analog actuation. The TQ suffix denotes the thin quad flat pack package, distinguishing it from through-hole DIP variants like the MX7548JN.

Digital To Analog Converters Replacement Considerations

The MX7548JCWG+ is a pin-compatible surface-mount alternative offering similar specifications in a SOIC-20 package. For higher resolution requirements, the MX7538 series provides 14-bit performance. Serial interface options are available via the MX7543 series if board space savings are prioritized over parallel bus simplicity.
