DAC7621E

Digital To Analog Converters Overview

The DAC7621E is a 12-bit digital-to-analog converter manufactured by Texas Instruments. It features parallel input architecture and provides an unbuffered current output. The device operates within a temperature range of -40°C to +85°C and is housed in a 16-pin package. Key performance specifications include a settling time of 0.2 microseconds and a maximum integral nonlinearity (INL) of +/- 1 LSB. It supports a sample rate of 10 MSPS and consumes approximately 27.5 mW of power.

Digital To Analog Converters Feature Summary

• Parallel input interface for direct digital connection
• Multiplying DAC architecture with unbuffered current output
• High-speed conversion capability with 0.2 microsecond settling time

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation
• Programmable gain amplifier circuits utilizing multiplying functionality
• Waveform generation applications needing fast settling times

Digital To Analog Converters Procurement Notes

Verify the specific revision level and packaging configuration when sourcing components. Ensure that the parallel interface requirements match the host system's digital bus capabilities. Confirm thermal management strategies are adequate for the specified operating temperature range and power consumption levels during integration.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution with parallel data input is required. It is suitable for applications demanding a 10 MSPS update rate and low settling time. Consider the unbuffered current output nature when designing load interfaces, as external buffering may be necessary for voltage output applications.

Digital To Analog Converters Part Context

This part belongs to the DAC7621 series of digital-to-analog converters from Texas Instruments. It shares architectural similarities with other parallel-input DACs in the Burr-Brown portfolio but is distinct from serial input variants like the DAC7611 or multiplying DACs like the DAC7821 which offer different interface and output characteristics.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes include the DAC7621EB and DAC7621E/1K. For alternative solutions, consider the AD5582 for quad-channel parallel input needs or the DAC7611 if serial interface compatibility is acceptable despite differing pinouts.
