Overview
The LTC2632CTS8-LZ10#TRPBF 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 a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 2.7V to 5.5V and utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. It includes rail-to-rail output buffers, double-buffered data latches, and a power-on reset circuit that clears outputs to zero-scale upon initialization. The component is housed in an 8-lead TSOT-23 package.
Feature Summary
- Dual 10-bit DACs with integrated 2.5V precision reference
- Rail-to-rail output buffers with guaranteed monotonicity
- 3-wire SPI/MICROWIRE interface supporting up to 50MHz clock
- Power-on reset to zero-scale for consistent system initialization
Applications
- Mobile communications systems
- Process control and industrial automation
- Automatic test equipment
- Portable battery-powered equipment
Procurement Notes
Verify the specific ordering suffix #TRPBF corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the C-grade commercial temperature range (0°C to 70°C) aligns with the operational environmental specifications of the target application design.
Selection Notes
Select this part when a dual-channel DAC with a fixed 2.5V internal reference is required. The LZ suffix ensures the outputs initialize to zero-scale at power-up, which is critical for applications where downstream circuits must remain inactive during startup. Ensure the supply voltage remains within the 2.7V to 5.5V range for specified performance.
Part Context
This component belongs to the LTC2632 family, which offers various resolution options including 8-bit, 10-bit, and 12-bit configurations. The LTS8 designation indicates the 8-lead plastic TSOT-23 package type. The LZ10 variant specifically denotes the 10-bit resolution with zero-scale power-on reset behavior and internal reference mode operation.
Replacement Considerations
Compatible substitutes within the same family include the LTC2632CTS8-LI10#TRPBF for mid-scale reset or the LTC2632CTS8-LZ12#TRPBF for higher 12-bit resolution. Verify pin compatibility and software register mapping when transitioning between different reset modes or resolutions.
