DAC0808LCM/NOPB

Digital To Analog Converters Overview

The DAC0808LCM/NOPB is an 8-bit digital-to-analog converter manufactured by Texas Instruments. It features a parallel interface and delivers current output in an unbuffered configuration. The device operates within a supply voltage range of 4.5 V to 18 V for both analog and digital power rails. Key performance metrics include a settling time of 100 ns, a sampling rate of 6.6 MS/s, and integral nonlinearity of +/- 0.5 LSB. Power consumption is specified at 33 mW. It functions across a temperature range of 0°C to +70°C and is housed in a 16-SOIC package.

Digital To Analog Converters Feature Summary

• Provides 8-bit resolution for digital-to-analog conversion tasks
• Utilizes a parallel data interface for input loading
• Delivers unbuffered current output signals
• Operates with single or dual power supplies between 4.5 V and 18 V

Digital To Analog Converters Applications

• Industrial process control systems requiring precise signal generation
• Programmable gain amplifier circuits
• Variable voltage reference implementations

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'LCMX' against the manufacturer's official datasheet to confirm pinout compatibility and electrical characteristics. Ensure the operating environment remains within the specified 0°C to +70°C temperature range. Confirm that the system design accommodates the unbuffered current output nature of the component, which typically requires external transimpedance amplification for voltage applications.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution with a parallel interface is required for cost-sensitive applications. The 100 ns settling time suits moderate-speed data acquisition systems. Designers must account for the current output topology, necessitating external circuitry if a voltage output is desired. Verify that the 16-SOIC package fits the available PCB real estate and thermal constraints.

Digital To Analog Converters Part Context

This part belongs to the DAC0808 series of 8-bit D/A converters from Texas Instruments. It shares architectural similarities with other members like the DAC0800 and DAC0802, differing primarily in packaging and specific electrical tolerances. The NOPB suffix indicates compliance with RoHS standards and absence of lead-based materials, aligning with modern environmental regulations for electronic components.

Digital To Analog Converters Replacement Considerations

The DAC0800LCMX/NOPB is a documented alternative within the same family. Verify pin compatibility and check if the 150 µs settling time of the DAC0800 meets the application requirements, as it is slower than the 100 ns specified for the DAC0808.
