Overview
The LTC2632CTS8-LI10 is a dual 10-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. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. Power-on reset defaults the outputs to mid-scale in internal reference mode. The component includes rail-to-rail output buffers and is guaranteed monotonic.
Feature Summary
- Dual 10-bit DACs with integrated 2.5V full-scale reference
- 10ppm/°C reference temperature coefficient
- 3-wire SPI/MICROWIRE serial interface with 50MHz clock rate
- Power-on reset to mid-scale in internal reference mode
Applications
- Mobile communications
- Process control and industrial automation
- Automatic test equipment
- Portable equipment
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm availability and lead times. Ensure the selected variant matches the required power-on reset behavior and supply voltage range for the target application environment.
Selection Notes
Select this part when a dual-channel solution with moderate resolution (10-bit) and low drift is required. The internal 2.5V reference simplifies design by eliminating external components. Verify that the 2.7V to 5.5V supply range aligns with the system power architecture.
Part Context
This component belongs to the LTC2632 family, which offers various combinations of resolution (8, 10, or 12 bits), accuracy grades, and power-on reset options. The 'LI' suffix indicates a 10-bit resolution with mid-scale reset in internal reference mode, while 'L' denotes the 2.5V full-scale voltage configuration.
Replacement Considerations
Other variants within the LTC2632 family, such as LTC2632CTS8-LZ10 or LTC2632ACTS8-LI10, may serve as functional substitutes if their specific resolution, accuracy grade, or reset behaviors match the design requirements.
