DAC37J82IAAV

Digital To Analog Converters Overview

The DAC37J82IAAV is a dual-channel, 16-bit digital-to-analog converter (DAC) from Texas Instruments. It operates at a maximum sample rate of 1.6 GSPS and utilizes a parallel interface for data input. The device features current source outputs with an unbuffered configuration. Power requirements include a 3.3 V analog supply and a 900 mV digital supply. It is housed in a 144-FCBGA package measuring 10x10 mm. The component supports an operating temperature range from -40°C to +85°C. Key performance metrics include a settling time of 10 ns, differential nonlinearity (DNL) of ±4 LSB, integral nonlinearity (INL) of ±6 LSB, and a spurious-free dynamic range (SFDR) of 81 dB.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing independent signal processing paths within a single integrated circuit.
• Ultra-high-speed operation capability supporting sample rates up to 1.6 GSPS for wideband applications.
• Integrated on-chip PLL to simplify clocking requirements while maintaining low jitter performance.
• Configurable serial control bus enabling flexible system integration and parameter adjustment.

Digital To Analog Converters Applications

• Software-defined radio systems requiring high-speed digital-to-analog conversion.
• Direct RF transmission architectures utilizing complex modulation schemes.
• Test and measurement equipment demanding precise waveform generation.
• Military radar systems necessitating robust multi-channel signal synthesis.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'AAV' against official datasheets to confirm pinout and electrical specifications match design requirements. Ensure ESD protection protocols are followed during handling due to moisture sensitivity level 3 classification. Confirm availability through authorized distributors as lead times may vary based on production schedules. Validate RoHS compliance status prior to final procurement decisions.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution is sufficient, as opposed to the quad-channel DAC37J84. Consider the parallel interface requirement; if serial JESD204B connectivity is preferred, evaluate alternative models within the family. Verify that the 1.6 GSPS speed meets system bandwidth needs without unnecessary power consumption associated with higher-speed variants.

Digital To Analog Converters Part Context

This part belongs to the DAC37J82 series, which serves as a lower channel-count variant compared to the DAC37J84. While sharing similar core technologies like the 16-bit resolution and 1.6 GSPS speed, it integrates only two converters instead of four. This reduction impacts total power consumption and board space requirements, making it suitable for applications where channel density is less critical than cost or power efficiency.

Digital To Analog Converters Replacement Considerations

The DAC37J84IAAV offers identical electrical characteristics but provides four channels instead of two. Designers must account for increased power dissipation and potential thermal management adjustments when substituting upward. No direct downward replacement exists within the same high-speed family offering fewer channels with equivalent performance metrics.
