LTC2633ACTS8-LI12#TRMPBF

Digital To Analog Converters Overview

The LTC2633ACTS8-LI12#TRMPBF is a dual 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in an 8-lead TSOT-23 package. It features an integrated precision reference with a full-scale output of 2.5V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 2.7V to 5.5V and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1.5 LSB, a supply current of 0.4mA at 3V, and rail-to-rail output buffers that are guaranteed monotonic over the –40°C to 125°C temperature range.

Digital To Analog Converters Feature Summary

• Dual 12-bit DACs with integrated 2.5V precision reference (10ppm/°C drift)
• Maximum INL error of ±1.5 LSB for high accuracy
• Rail-to-rail output buffers guaranteed monotonic from –40°C to 125°C
• Low power consumption: 0.4mA typical supply current at 3V

Digital To Analog Converters Applications

• Mobile communications systems
• Process control and industrial automation
• Power supply margining
• Portable equipment
• Automotive applications

Digital To Analog Converters Procurement Notes

Verify the #TRMPBF suffix indicates a 500-unit tape and reel packaging configuration, distinct from the standard 2,500-unit reel. Confirm the 'A' grade designation ensures the specified ±1.5 LSB maximum INL performance. Ensure the ordering code matches the specific power-on reset behavior defined by the 'I' suffix for mid-scale initialization in internal reference mode.

Digital To Analog Converters Selection Notes

Select this part when a compact 8-lead TSOT-23 footprint is required for dual-channel signal generation. The 'L' variant is appropriate for systems requiring a 2.5V full-scale output with a 2.7V minimum supply voltage. Choose the 'A' grade if strict linearity constraints (±1.5 LSB INL) are necessary compared to the standard ±2.5 LSB grade. Verify that the I²C address configuration via the CA0 pin aligns with the system bus topology.

Digital To Analog Converters Part Context

This component belongs to the LTC2633 family of dual DACs, which also includes variants with 10-bit and 8-bit resolutions, as well as different full-scale voltage options like the 4.096V 'H' grade. The 'ACTS8' designation specifies the commercial/high-temp grade, TSOT-23 package, and 12-bit resolution. The '#TRMPBF' suffix denotes lead-free construction and the specific 500-piece tape and reel shipping format.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include the LTC2633ACTS8-LI12#TR (2,500-unit reel) or the LTC2633ACTS8-HI12#TRMPBF for a 4.096V full-scale output. For higher resolution requirements, consider the LTC2634 quad-channel variant, though it requires a larger package.
