Overview
The LTC2640AITS8-LZ12#TRMPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 2.5V and operates on a single supply voltage ranging from 2.7V to 5.5V. The device utilizes a SPI/MICROWIRE compatible 3-wire serial interface supporting clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a settling time of 4.1µs at 3V, and low power consumption of 180µA at 3V. It incorporates a power-on reset circuit that clears the output to zero-scale upon initialization.
Feature Summary
- Integrated high-accuracy reference providing 2.5V full-scale output with 10ppm/°C drift
- Maximum INL error of ±1 LSB for 12-bit resolution
- SPI/MICROWIRE compatible 3-wire serial interface with 50MHz clock capability
- Power-on reset to zero-scale and asynchronous DAC clear pin
Applications
- Mobile communications systems
- Process control and industrial automation
- Automatic test equipment
- Portable battery-powered equipment
- Optical networking devices
Procurement Notes
Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel packaging configuration as defined in the manufacturer's part numbering system. Confirm the temperature grade 'I' corresponds to the -40°C to 85°C operating range and the package type TS8 matches the 8-lead plastic TSOT-23 form factor required for the design.
Selection Notes
Select this component when a 12-bit resolution with ±1 LSB INL accuracy is required in a compact TSOT-23 package. Ensure the application supply voltage remains within the 2.7V to 5.5V range suitable for the 'L' variant full-scale output. Consider the I-grade temperature rating if operation outside the commercial range is necessary.
Part Context
This part belongs to the LTC2640 family of single voltage-output DACs available in 12-, 10-, and 8-bit resolutions. The family shares a common architecture featuring integrated references and rail-to-rail output buffers. Variants differ by resolution, power-on reset behavior, and full-scale voltage options (2.5V or 4.096V).
Replacement Considerations
Direct substitutes within the same family include LTC2640AITS8-LM12#TRMPBF for mid-scale reset or LTC2640AITS8-HZ12#TRMPBF for 4.096V full-scale output. Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
