Overview
The LTC2632CTS8-HI8 is a dual 8-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 4.096V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 4.5V to 5.5V. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. The part includes power-on reset circuitry that defaults outputs to mid-scale in internal reference mode upon startup.
Feature Summary
- Dual 8-bit DACs with integrated 4.096V precision reference
- Rail-to-rail output buffers with guaranteed monotonicity
- 3-wire serial interface operating at clock rates up to 50MHz
- 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 component when a dual-channel, low-pin-count DAC is required with a fixed 4.096V full-scale range. The HI suffix indicates operation within the 4.5V to 5.5V supply range. Consider the H-grade temperature rating (-40°C to 125°C) if automotive or wide-temperature industrial environments are involved.
Part Context
This part belongs to the LTC2632 family, which offers various combinations of resolution (8-, 10-, 12-bit), full-scale voltage (2.5V or 4.096V), and power-on reset options. The CTS8 designation specifies the commercial temperature grade and the 8-lead TSOT-23 package type.
Replacement Considerations
Direct substitutes include other parts within the LTC2632 family such as the LTC2632CTS8-HI12 for higher resolution or LTC2632CTS8-LI8 for lower supply voltage requirements. Verify pin compatibility and electrical specifications before substitution.
