Overview
The LTC2632HTS8-LX8#TRMPBF is a dual 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in an 8-lead TSOT-23 package. It features an integrated high-accuracy 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 interface supporting clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity (INL) of ±2.5LSB, rail-to-rail output buffers, and guaranteed monotonicity. Power-on reset options allow the outputs to initialize to mid-scale in external reference mode.
Feature Summary
- Dual 8-bit DACs with integrated 2.5V full-scale reference
- 3-wire serial interface with SCK frequencies up to 50MHz
- Power-on reset to mid-scale in external reference mode
- Automotive temperature grade (-40°C to +125°C)
Applications
- Mobile communications
- Process control and industrial automation
- Automatic test equipment
- Portable equipment
- Automotive systems
Procurement Notes
Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel configuration. Confirm that the LX designation corresponds to the external reference power-on reset mode for the 2.5V full-scale variant. Ensure the automotive temperature range requirement aligns with the H-grade specification before procurement.
Selection Notes
Select this component when a dual-channel, low-pin-count DAC is required for automotive or industrial applications. The LX suffix is critical if the system design mandates a mid-scale initialization during power-up while utilizing an external reference voltage. Verify that the 2.5V internal reference span meets the application's output voltage requirements.
Part Context
This part belongs to the LTC2632 family of dual DACs, which offers various combinations of resolution (8, 10, or 12 bits), accuracy grades, and power-on reset behaviors. The HTS8 package identifies it as the automotive-grade version in the compact TSOT-23 form factor, distinguishing it from commercial C-grade or higher-resolution A-grade variants within the same series.
Replacement Considerations
Direct substitutes within the same family include other LTC2632 variants with different resolutions or reset modes, such as LTC2632HTS8-LI8#TRMPBF for internal reference reset. Cross-family replacements require matching the 8-bit resolution, dual-channel architecture, and TSOT-23 package constraints.
