Overview
The LTC2632CTS8-HZ10 is a dual 12-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 providing a full-scale output of 4.096V with a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 4.5V to 5.5V and communicates via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. It includes rail-to-rail output buffers, guaranteed monotonicity, and a power-on reset function that initializes outputs to zero-scale.
Feature Summary
- Dual 12-bit DACs with integrated 4.096V reference (10ppm/°C drift)
- SPI/MICROWIRE 3-wire serial interface with 50MHz clock rate
- Power-on reset to zero-scale for consistent system initialization
- Rail-to-rail output buffers with ±1.5LSB maximum INL error
Applications
- Mobile communications
- Process control and industrial automation
- Automatic test equipment
- Portable equipment
- Automotive systems
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 supply voltage range (4.5V to 5.5V for the H-grade) and temperature specifications before procurement.
Selection Notes
Select this component when a dual-channel DAC with high accuracy and low drift is required in a compact package. The H-grade designation indicates a 4.096V full-scale output requiring a minimum 4.5V supply. The Z-suffix ensures the outputs initialize to zero upon power-up, which is critical for applications where downstream circuits must remain inactive during startup.
Part Context
This part belongs to the LTC2632 family of dual DACs available in various resolutions (8, 10, 12-bit) and accuracy grades. The CTS8 designation specifies the commercial temperature range (0°C to 70°C) and the 8-lead TSOT-23 package. Other variants include the L-grade for 2.5V operation and different power-on reset options (I or X suffixes).
Replacement Considerations
Direct substitutes within the same package and pinout include other LTC2632 variants such as LTC2632CTS8-HI10 or LTC2632CTS8-LZ12, provided the supply voltage and reset requirements align. Cross-family replacements require verification of interface compatibility and pin mapping.
