DAC0830LCN/NOPB

Digital To Analog Converters Overview

The DAC0830LCN/NOPB is an 8-bit microprocessor-compatible, double-buffered digital-to-analog converter manufactured by Texas Instruments. It features a CMOS/Si-Cr architecture with an R-2R resistor ladder network and operates on a single power supply ranging from 5 V to 15 VDC. The device provides current outputs (IOUT1 and IOUT2) with a typical settling time of 1 μs and low power dissipation of 20 mW. It utilizes parallel digital inputs compatible with TTL voltage levels and includes an internal feedback resistor for external operational amplifier configurations.

Digital To Analog Converters Feature Summary

• Double-buffered input and DAC registers allow simultaneous updating of multiple converters via a common transfer strobe.
• Direct interface capability with popular microprocessors including the 8080, 8048, 8085, and Z80 families.
• Supports full four-quadrant multiplication using bipolar reference voltages within the ±10 V range.
• TTL logic input compatibility ensures seamless integration without additional level-shifting circuitry.

Digital To Analog Converters Applications

• Microprocessor-based data acquisition systems requiring analog output generation.
• Programmable gain amplifiers and variable voltage/current sources.
• Waveform generation circuits utilizing function ROMs or binary counters.
• Industrial process control loops requiring digitally adjustable analog signals.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'LCN' confirms the commercial temperature range of 0°C to +70°C and the PDIP-20 package style. Confirm that the 'NOPB' designation indicates lead-free compliance and RoHS adherence as per the manufacturer's standard product change notifications. Ensure the application design accounts for the required external operational amplifier to convert the current output to a voltage signal.

Digital To Analog Converters Selection Notes

Select this component when system requirements demand an 8-bit resolution with microprocessor interface compatibility and double buffering for synchronized multi-channel updates. Consider the DAC0830 over the DAC0832 if tighter linearity specifications are necessary, as the DAC0830 offers superior linearity performance. Evaluate the need for an external op amp with low bias current to minimize offset errors associated with the internal feedback resistor.

Digital To Analog Converters Part Context

The DAC0830 belongs to the MICRO-DAC family of 8-bit multiplying digital-to-analog converters. It shares pinout compatibility with the 12-bit DAC1230 series, allowing for potential resolution upgrades in existing designs without hardware modifications. This series is designed for applications requiring direct interfacing with standard microprocessor buses and flexible operating modes including single-buffered, double-buffered, and flow-through configurations.

Digital To Analog Converters Replacement Considerations

The DAC0832 is a pin-compatible alternative within the same family but exhibits different linearity characteristics. Verify if the looser linearity specs of the DAC0832 meet the application requirements before substitution. No other direct functional replacements are documented in the provided datasheet.
