TLC7528IDWR

Digital To Analog Converters Overview

The TLC7528IDWR is a dual 8-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor ladder architecture to provide two independent current outputs with unbuffered configurations. The device supports parallel data interfaces and operates within a supply voltage range of 4.75 V to 15.5 V for both analog and digital domains. Key performance specifications include a settling time of 100 ns, a gain error of 1% FSR, and integral nonlinearity of ±0.5 LSB. It functions reliably across an industrial temperature range from -40°C to +85°C and is housed in a 20-pin TSSOP surface-mount package.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent 8-bit DACs within a single integrated circuit.
• High-speed conversion capability with a typical settling time of 100 nanoseconds.
• Flexible power supply design accommodating standard 5 V or bipolar ±5 V/±12 V systems.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'IDWR' to confirm the industrial temperature grade (-40°C to +85°C) and the TSSOP-20 tape-and-reel packaging format. Ensure that the procurement order matches the required operating environment and reel quantity specifications defined in the official datasheet to avoid functional mismatches.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution is required to save board space compared to using single-channel devices. Consider the unbuffered current output nature, which necessitates external operational amplifiers for voltage-mode applications. Verify that the system's parallel bus timing requirements align with the device's setup and hold times.

Digital To Analog Converters Part Context

This part belongs to the TLC7528 family of high-speed dual DACs. It serves as a cost-effective alternative to higher-resolution converters in applications where 8-bit precision is sufficient. The device shares architectural similarities with other industry-standard parts but offers specific pinout and electrical characteristics unique to the Texas Instruments implementation.
