DAC0802LCMX/NOPB

Digital To Analog Converters Overview

The DAC0802LCMX/NOPB is an 8-bit digital-to-analog converter manufactured by Texas Instruments, originally based on National Semiconductor designs. It features a parallel input interface and offset binary coding. The device operates with analog supply voltages ranging from ±4.5 V to ±18 V and digital supplies from +4.5 V to +18 V. Key electrical parameters include a settling time of 0.1 µs (100 ns), a maximum linear error of 0.1%, and a power consumption of 33 mW. It is housed in a 16-pin plastic small-outline package (SOP-16/SOIC-Narrow) and supports an operating temperature range of 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Provides unbuffered current output suitable for external transimpedance amplification
• Supports multiplying DAC architecture for variable reference applications
• Features low power consumption for efficient thermal management
• Includes internal latch structure for simplified parallel data interfacing

Digital To Analog Converters Applications

• Battery-powered instrumentation systems requiring low power operation
• Industrial process control loops utilizing current-mode outputs
• Programmable gain amplifier circuits with external feedback networks
• Waveform generation systems requiring precise settling times

Digital To Analog Converters Procurement Notes

Verify the presence of the NOPB suffix to confirm lead-free compliance and RoHS adherence. Confirm the manufacturer origin, as this component may be sourced through authorized distributors like Rochester Electronics or Texas Instruments directly. Ensure the specific package variant matches the required PCB footprint for SOP-16 integration.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution with parallel interface is sufficient for the application. Consider the unbuffered current output requirement; an external operational amplifier is necessary to convert the output to a voltage signal. Verify that the supply voltage range aligns with the system's available power rails and that the 0.1% linearity meets the accuracy requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC0800/DAC0802 family of 8-bit multiplying DACs. The DAC0802 variant specifically utilizes offset binary coding, distinguishing it from the DAC0800 which uses straight binary code. Both share similar electrical characteristics and pinouts, facilitating design flexibility within the same product line.

Digital To Analog Converters Replacement Considerations

The DAC0800LCMX/NOPB serves as a functional substitute if straight binary coding is acceptable instead of offset binary. Other compatible parts in the series include DAC0802LCM and DAC0802LCM/NOPB, ensuring identical pinout and performance specifications.
