Overview
The LTC2632HTS8-LZ8 is a dual 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 4.096V and operates within a supply voltage range of 4.5V to 5.5V. The device utilizes a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity error of ±2.5LSB, rail-to-rail output buffers, and guaranteed monotonicity. The power-on reset function clears the outputs to zero-scale in internal reference mode.
Feature Summary
- Dual 8-bit DACs with integrated 10ppm/°C precision reference
- 4.096V full-scale output capability
- Power-on reset to zero-scale in internal reference mode
- Rail-to-rail output buffers with guaranteed monotonicity
Applications
- Mobile communications
- Process control and industrial automation
- Automatic test equipment
- Portable equipment
- Automotive systems
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm availability through designated sales channels as tape and reel options may vary by region. Ensure compatibility with system power supply requirements before procurement.
Selection Notes
Select this component for applications requiring dual low-resolution DACs with high accuracy references. The 4.5V minimum supply voltage distinguishes it from lower-voltage variants. Verify that the zero-scale power-on reset behavior aligns with downstream circuit safety requirements during initialization.
Part Context
This part belongs to the LTC2632 family of dual DACs available in various resolutions (8, 10, 12-bit) and accuracy grades. The 'H' designation indicates the 4.096V full-scale variant, while 'LZ' specifies the zero-scale power-on reset configuration. The TS8 package denotes the 8-lead plastic TSOT-23 form factor.
Replacement Considerations
Direct substitutes within the same family include other LTC2632 variants with different resolutions or reset behaviors. Cross-family replacements require matching supply voltage ranges, interface protocols, and pinout configurations.
