TLC7528CNS

Digital To Analog Converters Overview

The TLC7528CNS is a dual-channel, 8-bit multiplying digital-to-analog converter (DAC) manufactured by Texas Instruments. It features an R-2R resistor ladder architecture with independent internal data latches for each channel. The device operates on parallel interfaces and supports analog and digital supply voltages ranging from 4.75 V to 15.5 V. Key electrical specifications include a settling time of 100 ns, a sampling rate of 10 MS/s, and a typical power consumption of 7.5 mW. Gain error is specified at 1% FSR, with integral nonlinearity (INL) of ±0.5 LSB. It functions within a commercial temperature range of 0°C to +70°C and is housed in a 20-pin PDIP package.

Digital To Analog Converters Feature Summary

• Dual-channel design with independent internal data latches simplifies microprocessor interfacing.
• Multiplying capability allows support for both two-quadrant and four-quadrant operations.
• Monotonic performance across the full A/D conversion range ensures stable operation.

Digital To Analog Converters Applications

• Microprocessor-controlled gain setting circuits
• Signal control systems requiring fast settling times
• Digital signal processor (DSP) interface applications

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'NS' against the official Texas Instruments datasheet to confirm the package type and temperature grade. Ensure compatibility with existing PCB footprints for the 20-pin DIP configuration. Check for RoHS compliance status if required by local regulations. Confirm availability through authorized distributors as lead times may vary based on production cycles.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 8-bit resolution is required with low power consumption. The parallel interface suits designs where pin count is not the primary constraint. Consider the 100 ns settling time for applications needing moderate speed. Verify that the unbuffered current output meets the load requirements or requires external amplification.

Digital To Analog Converters Part Context

The TLC7528CNS belongs to the TLC7528 family of dual 8-bit multiplying DACs. It is functionally compatible with other industry-standard parts like the AD7528 and PM-7528. The 'C' suffix typically denotes the commercial temperature range, while 'NS' indicates the specific package variant. This series is designed for cost-effective solutions in general-purpose analog control applications.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible substitutes include the AD7528JRZ and PM-7528. Verify electrical parameters such as settling time and INL before substitution. Ensure the replacement part supports the same voltage range and interface timing requirements.
