Overview
The LTC2632CTS8-LX10 is a dual 10-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 ranging from 2.7V to 5.5V. The device utilizes a 3-wire SPI/MICROWIRE compatible serial interface for communication. A key characteristic is its power-on reset configuration, which sets the outputs to mid-scale when using an external reference mode. The component is housed in an 8-lead TSOT-23 package and supports rail-to-rail output buffering.
Feature Summary
- Dual 10-bit DACs with integrated 2.5V full-scale internal reference
- Power-on reset to mid-scale in external reference mode
- 3-wire SPI/MICROWIRE compatible serial interface
- Single supply operation from 2.7V to 5.5V
Applications
- Mobile communications
- Process control and industrial automation
- Portable equipment
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm availability and lead times. Ensure the external reference voltage requirements align with the mid-scale reset behavior specified for the LX variant. Confirm package type and temperature grade match the design specifications before procurement.
Selection Notes
Select this part when a dual-channel DAC with mid-scale initialization under external reference conditions is required. The LX suffix specifically configures the power-on reset state for external reference usage. Compare against LI or LZ variants if zero-scale or internal-reference mid-scale resets are preferred instead. Ensure the system supply voltage remains within the 2.7V to 5.5V range for proper operation.
Part Context
This component belongs to the LTC2632 family of dual voltage-output DACs. The family offers various resolutions including 8-bit, 10-bit, and 12-bit options. Different suffixes denote variations in power-on reset behavior and reference modes. The CTS8 designation indicates the commercial temperature grade and the 8-lead TSOT-23 package style.
Replacement Considerations
Direct replacements within the same family include LTC2632CTS8-LI10 for internal reference mid-scale reset or LTC2632CTS8-LZ10 for zero-scale reset. Other resolution variants like LTC2632CTS8-LX12 or LTC2632CTS8-LX8 share the same pinout and interface but differ in accuracy and code structure.
