DAC11001BPFBR

Digital To Analog Converters Overview

The DAC11001B is a 20-bit, low-noise, ultra-low harmonic distortion, fast-settling, high-voltage-output digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a resolution of 20 bits with monotonicity guaranteed by design. The device offers an integral linearity (INL) of ±1 LSB maximum and differential nonlinearity (DNL) of ±1 LSB maximum. Output noise density is specified at 7 nV/√Hz, while the code-independent glitch impulse is 1 nV-s. Total harmonic distortion (THD) reaches -118 dB at a 20-kHz output frequency with a 1-MHz DAC update rate. Full-scale settling time to 0.1% FSR is 1 µs. The component operates within a temperature range of –40°C to +125°C and utilizes a 50-MHz, 4-wire SPI-compatible interface.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix PFBR against the manufacturer's package option addendum to confirm the 48-pin TQFP physical dimensions and thermal characteristics. Ensure that the selected variant matches the required operating temperature range and power supply specifications for the intended application environment before finalizing procurement.

Digital To Analog Converters Selection Notes

Select the DAC11001B when high accuracy and low noise are critical requirements. The device supports asymmetric output ranges using external references. Consider the integrated precision resistors if board space is limited. Verify compatibility with the system's digital logic levels, as the interface supports IOVDD from 1.7 V to 5.5 V. Ensure adequate power supply sequencing is implemented to meet the recommended operating conditions.

Digital To Analog Converters Part Context

The DAC11001B belongs to the DACx1001 family, which includes 20-bit, 18-bit, and 16-bit variants. This specific model represents the highest resolution option in the series, designed for applications demanding ultra-low harmonic distortion and fast settling times. It shares functional similarities with other members but offers distinct performance metrics tailored for high-precision analog signal generation.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include DAC11001APFBR and DAC11001APFBT. These parts share identical electrical specifications and pinouts but may differ in packaging or reel quantities. Verify that any substitute maintains the 48-pin TQFP form factor and meets the same thermal and electrical performance criteria.
