DAC0830LCN

Digital To Analog Converters Overview

The DAC0830LCN is an 8-bit, single-channel digital-to-analog converter manufactured by Texas Instruments. It features a CMOS/Si-Cr architecture with a deposited silicon-chromium R-2R resistor ladder network for excellent temperature tracking. The device provides current outputs (IOUT1 and IOUT2) and includes an internal feedback resistor (Rfb). It supports double-buffered, single-buffered, or flow-through digital data inputs, allowing simultaneous updating of multiple converters. The part operates on a single power supply ranging from 5 VDC to 15 VDC, with a typical power dissipation of 20 mW. It is housed in a 20-pin PLCC package and is rated for an operating temperature range of 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Double-buffered digital input architecture enables simultaneous updating of multiple DACs via a common strobe signal.
• Direct interface capability with popular microprocessors including the 8080, 8048, 8085, and Z80.
• Supports full 4-quadrant multiplication of bipolar reference voltages using a precision R-2R ladder network.
• TTL logic input voltage level compatibility eliminates the need for external interfacing logic.

Digital To Analog Converters Applications

• Microprocessor-based data acquisition systems requiring direct CPU interface.
• Process control loops utilizing digitally controlled analog signals.
• Function generation circuits driven by binary counters or ROMs.
• Multi-channel systems requiring synchronized output updates.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'LCN' confirms the 20-pin PLCC package and commercial temperature range (0°C to +70°C). Ensure the source document matches the SNAS534B revision date. Confirm that the ordering information aligns with the manufacturer's current production status for this legacy component series.

Digital To Analog Converters Selection Notes

Select the DAC0830LCN when an 8-bit resolution is sufficient and direct microprocessor compatibility is required. This part is suitable for applications needing low power consumption and simple interfacing without external logic gates. Consider the DAC1230 if higher 12-bit resolution is needed, as it maintains pin compatibility with the same addressing scheme.

Digital To Analog Converters Part Context

The DAC0830 belongs to the MICRO-DAC family of microprocessor-compatible converters. It serves as the 8-bit member alongside other variants like the DAC0832. The device is designed to replace older TTL-based DACs while offering improved power efficiency and linearity through its CMOS/Si-Cr technology and double-buffering capabilities.

Digital To Analog Converters Replacement Considerations

The DAC1230 is a pin-compatible 12-bit upgrade option within the same family. Substitution requires tying address bit A0 to the ILE pin to handle the additional two bytes of data during write operations without hardware changes.
