DAC11001APFBR

Digital To Analog Converters Overview

The DAC11001APFBR is a 20-bit, single-channel digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R architecture to provide voltage output without buffering. The device features a maximum integral nonlinearity (INL) of ±4 LSB and differential nonlinearity (DNL) of ±1 LSB. It operates with analog supply voltages ranging from 4.5V to 5.5V and digital supply voltages from 2.7V to 5.5V. The typical settling time is 2.5µs. Communication is handled via a SPI interface. The component is housed in a 48-TQFP package measuring 7x7 mm and supports an operating temperature range from -40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'PFBR' corresponds to the tape and reel packaging configuration when sourcing. Confirm that the required operating temperature range aligns with the industrial specification limits. Ensure the host system's SPI clock rates do not exceed the maximum supported frequency of 50MHz. Validate pin compatibility with the target PCB footprint before finalizing procurement decisions.

Digital To Analog Converters Selection Notes

Select this component when high resolution and low noise are critical requirements. The 20-bit resolution suits applications demanding fine voltage steps. The unbuffered voltage output requires external buffering if driving low impedance loads. Consider the 48-TQFP package size constraints during mechanical design. Verify that the single-channel requirement matches the system architecture needs.
