TLC7528EDW

Digital To Analog Converters Overview

The TLC7528EDW is a dual 8-bit multiplying digital-to-analog converter (DAC) manufactured by Texas Instruments. It features an R-2R resistor ladder architecture and provides two independent current outputs in an unbuffered configuration. The device operates with parallel data interfaces and supports analog and digital supply voltages ranging from 5 V to 15 V. Key performance specifications include a settling time of 100 ns, a sampling rate of 10 MS/s, and a power consumption of 7.5 mW. Integral nonlinearity is specified at ±0.5 LSB, with a gain error of 1% FSR. It functions within a temperature range of -40°C to +85°C and is housed in a 20-SOIC package.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent 8-bit DACs within a single integrated circuit.
• Multiplying capability allowing the reference input to function as a second digital input for signal processing applications.
• CMOS construction utilizing an R-2R ladder network for low power consumption and high-speed operation.
• Parallel interface design enabling direct connection to microprocessors and digital logic systems.

Digital To Analog Converters Applications

• Programmable gain amplifiers requiring precise analog scaling.
• Waveform generation circuits such as function generators or pulse width modulators.
• Digital potentiometer replacements for variable voltage references.
• Closed-loop control systems needing rapid analog output updates.

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for lead-free markings on the package surface. Ensure the SOIC-20 footprint matches the target PCB layout dimensions. Review the latest datasheet revision for any pinout modifications or updated electrical limits before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 8-bit resolution is required with parallel interface compatibility. Consider the 100 ns settling time for bandwidth limitations in high-speed applications. Verify that the unbuffered current output aligns with the downstream load requirements or external amplifier needs. Ensure the 5 V to 15 V supply range fits the system power architecture.

Digital To Analog Converters Part Context

The TLC7528EDW belongs to the TLC7528 family of dual multiplying DACs from Texas Instruments. It shares functional similarities with the TLC7628 but differs in specific electrical characteristics and packaging options. The 'EDW' suffix indicates the extended industrial temperature grade and the 20-pin small-outline integrated circuit package format used for surface-mount assembly.

Digital To Analog Converters Replacement Considerations

The TLC7528IDW is a manufacturer-recommended alternative within the same series. Other potential substitutes include the AD7528JRZ from Analog Devices, which offers similar functionality but may require verification of pin compatibility and electrical parameter alignment.
