TLC7528IN

Digital To Analog Converters Overview

The TLC7528IN is a dual 8-bit multiplying digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor ladder architecture and accepts parallel data inputs to drive two independent current outputs. The device operates with analog and digital supply voltages ranging from 5V to 15V. Key electrical specifications include a maximum settling time of 100ns, integral nonlinearity (INL) and differential nonlinearity (DNL) of ±0.5 LSB maximum, and a working temperature range of -40°C to +85°C. It is housed in a 20-pin DIP package.

Digital To Analog Converters Feature Summary

• Dual-channel design providing two independent 8-bit DACs within a single component
• Multiplying capability allowing the reference input to function as a second digital word for gain control
• Unbuffered current output configuration suitable for external transimpedance amplification
• Parallel interface compatibility for straightforward microcontroller or logic integration

Digital To Analog Converters Applications

• Programmable gain amplifier circuits requiring precise analog scaling
• Waveform generation systems utilizing multiplying DAC functionality
• Industrial process control loops needing dual-channel signal conditioning
• Battery-powered instrumentation where low power consumption is critical

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'IN' corresponds to the PDIP-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation, as legacy parts may have varying environmental certifications. Ensure the supplier provides valid traceability records for industrial applications. Cross-reference the datasheet revision date to confirm pinout consistency with existing designs.

Digital To Analog Converters Selection Notes

Select this component when dual-channel performance is required without occupying separate board space for individual converters. The multiplying feature distinguishes it from standard fixed-gain DACs, enabling software-adjustable attenuation or amplification. Consider the unbuffered current output requirement; external operational amplifiers are necessary for voltage-mode applications. Evaluate the 100ns settling time against system bandwidth requirements to ensure adequate response speed.

Digital To Analog Converters Part Context

The TLC7528 belongs to the broader family of CMOS multiplying DACs produced by Texas Instruments. It shares architectural similarities with the single-channel TLC7524 and other variants like the TLC7528IDW. This series is designed for general-purpose analog signal processing tasks where moderate resolution and speed are sufficient. The 'IN' suffix specifically denotes the through-hole DIP packaging option compared to surface-mount alternatives.

Digital To Analog Converters Replacement Considerations

• TLC7528IDW: Surface-mount equivalent with identical electrical characteristics
