DAC5571IDBVT

Digital To Analog Converters Overview

The DAC5571IDBVT is a single-channel, 8-bit digital-to-analog converter manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and features an I2C-compatible two-wire serial interface with clock rates up to 3.4 Mbps. The device includes a precision on-chip output amplifier providing rail-to-rail output swing from 0 V to VDD. Key electrical parameters include a settling time of 8 µs, a sampling rate of 188 kS/s, and a typical operating current of 155 µA. Differential nonlinearity (DNL) and integral nonlinearity (INL) are specified at ±0.5 LSB and ±0.25 LSB respectively in some datasheets, while others cite ±1 LSB. It functions within a temperature range of -40°C to +105°C and is housed in a SOT-23-6 package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix IDBVT corresponds to the SOT-23-6 surface-mount package and tape-and-reel shipping configuration. Confirm RoHS compliance status and lead-free manufacturing details against the latest manufacturer datasheet revision. Ensure the ordering part number matches the required temperature grade and packaging quantity for your production needs.

Digital To Analog Converters Selection Notes

Select this component when a low-cost, single-channel 8-bit resolution is sufficient for voltage output applications. It is suitable for designs requiring minimal external components due to the integrated buffer and I2C interface. Consider the 188 kS/s update rate and 8 µs settling time for bandwidth requirements. Evaluate the 2.7 V to 5.5 V supply range compatibility with system power rails.

Digital To Analog Converters Part Context

The DAC5571IDBVT belongs to the DAC5571 family of low-power, single-channel, 8-bit buffered voltage output DACs. This series shares architectural similarities with higher-resolution variants like the DAC6571 (10-bit) and DAC7571 (12-bit), as well as multi-channel versions such as the DAC5574. All members utilize the same I2C interface and compact SOT-23 packaging options.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same family include DAC5571IDBVR (same function, different reel packaging). For higher resolution, consider DAC6571IDBVT or DAC7571IDBVT. Verify pinout compatibility and software register mapping when migrating between these related part numbers.
