Overview
The LTC2632CTS8-LZ8#TRMPBF is a dual 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated 10ppm/°C reference with a full-scale output of 2.5V. The device operates on a single supply ranging from 2.7V to 5.5V and utilizes a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. It includes rail-to-rail output buffers, guaranteed monotonicity, and a power-on reset circuit configured to clear outputs to zero-scale in internal reference mode upon startup.
Feature Summary
- Dual 8-bit DACs with integrated 2.5V full-scale reference
- Rail-to-rail output buffers with guaranteed monotonicity
- Power-on reset to zero-scale in internal reference mode
- 3-wire serial interface supporting SCK frequencies up to 50MHz
Applications
- Mobile communications
- Process control and industrial automation
- Automatic test equipment
- Portable equipment
Procurement Notes
Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel configuration. Confirm that the 'L' designation corresponds to the 2.7V to 5.5V supply range and 2.5V full-scale output. Ensure the 'Z' suffix matches the required zero-scale power-on reset behavior for the application design.
Selection Notes
Select this part when a low-pin-count solution for dual 8-bit conversion is required. The 8-bit resolution offers faster settling times compared to higher-resolution variants. Verify that the 2.5V internal reference range meets system requirements; otherwise, consider external reference modes or different full-scale options within the family.
Part Context
This component belongs to the LTC2632 family of dual DACs available in 8-, 10-, and 12-bit resolutions. Variants differ by accuracy grade (standard vs. A-grade), full-scale voltage (2.5V vs. 4.096V), and power-on reset states. The LTS8 package provides an 8-lead TSOT-23 form factor suitable for space-constrained designs.
Replacement Considerations
Direct substitutes include other LTC2632 variants such as LTC2632CTS8-LI8#TRMPBF if mid-scale reset is acceptable, or LTC2632CTS8-HZ8#TRMPBF if a 4.096V full-scale range is needed. Higher resolution versions like the LTC2632CTS8-LZ12#TRMPBF are pin-compatible but offer different linearity specifications.
