TLC7226INE4

Digital To Analog Converters Overview

The TLC7226INE4 is a quad 8-bit digital-to-analog converter featuring integrated output buffer amplifiers and interface logic. It utilizes a common 8-bit TTL/CMOS-compatible input port with individual DAC latches selected by address inputs A0 and A1. The device operates from a single supply (VDD = 11.4 V to 16.5 V, VSS = AGND) or dual supplies (VDD = 11.4 V to 16.5 V, VSS = -5.5 V to 0 V). Key electrical parameters include a settling time of 5 µs to 1/2 LSB, a resolution of 8 bits, and a total unadjusted error of ±2 LSB. The I suffix indicates an operating temperature range of -30°C to 85°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 8-bit voltage-output DACs with dedicated buffer amplifiers on a single monolithic chip.
• Features microprocessor-compatible control logic with separate latches for each channel, allowing sequential data loading via a common bus.
• Supports flexible power configurations including single-supply operation and direct bipolar output without external components.

Digital To Analog Converters Applications

• Process control systems requiring multi-channel analog signal generation.
• Automatic test equipment for generating precise voltage levels.
• Automatic calibration of large system parameters such as gain and offset.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix E4 confirms lead-free and RoHS compliance status as defined by Texas Instruments. Confirm the package type matches the required PCB footprint, typically 20-pin PDIP for the IN variant. Ensure the temperature grade corresponds to the application environment requirements before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when multiple low-cost, 8-bit voltage outputs are needed in a compact form factor. Consider the 5 µs settling time and ±2 LSB total unadjusted error for accuracy requirements. Verify that the supply voltage range and reference voltage constraints align with the system design, particularly if using single-supply operation.

Digital To Analog Converters Part Context

The TLC7226 series consists of four 8-bit DACs fabricated in LinBiCMOS technology. This process integrates high-speed digital logic with precision analog circuits. The family includes variants like the TLC7226C, TLC7226I, and TLC7226M, differentiated primarily by their operating temperature ranges and available package options.

Digital To Analog Converters FAQ

How is bipolar output achieved without external amplifiers?

Bipolar operation is achieved by biasing the AGND terminal to VSS. This configuration allows the output to swing between positive and negative voltages relative to DGND without additional components.

What is the maximum output current capability?

Each output buffer amplifier is capable of sourcing up to 5 mA into a 2-kΩ load.

How does the WR signal control data latching?

When WR is low, the selected DAC latch is transparent. Data is latched into the addressed DAC on the rising edge of the WR signal.
