DAC3161IRGCT

Digital To Analog Converters Overview

The DAC3161IRGCT is a single-channel, high-speed digital-to-analog converter manufactured by Texas Instruments. It features a current source architecture with configurable resolution options of 14-bit, 12-bit, or 10-bit. The device supports a maximum sampling rate of 500 MSPS and achieves a settling time of 11 ns. Key performance metrics include a differential nonlinearity (DNL) of +/- 0.2 LSB and an integral nonlinearity (INL) of +/- 0.5 LSB. It operates on analog supply voltages of 1.8 V and 3.3 V, with a digital supply voltage of 1.8 V. The component utilizes a parallel interface, consumes 375 mW of power, and is housed in a VQFN-64 package suitable for surface mount installation within an operating temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'RGCT' corresponds to the VQFN-64 package and reel/cut tape packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the parallel interface compatibility matches the host system's digital logic levels. Validate that the 1.8 V digital and 1.8 V/3.3 V analog supply requirements align with the target power design constraints.

Digital To Analog Converters Selection Notes

Select this component when a single-channel DAC with 500 MSPS throughput is required. Choose the 12-bit mode for optimal balance between resolution and bandwidth if 14-bit precision is unnecessary. Consider the VQFN-64 package for space-constrained PCB layouts. Verify thermal management capabilities given the 375 mW power dissipation rating in the specified operating temperature range.

Digital To Analog Converters Part Context

This part belongs to the DAC3161 series from Texas Instruments, designed for high-performance data conversion tasks. It shares architectural similarities with other members like the DAC3171 but offers distinct resolution and linearity specifications. The series targets applications requiring fast settling times and low power consumption in a compact form factor.

Digital To Analog Converters Replacement Considerations

The DAC3161IRGCR serves as a tray-packaged alternative to the IRGCT cut-tape variant. Evaluate pinout and electrical parameter equivalence before substitution. No direct cross-manufacturer replacements are confirmed in public documentation.
