Overview
The LTC2632CTS8-HI8#TRPBF 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 a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 4.5V to 5.5V. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface for communication, supporting clock rates up to 50MHz. The part includes rail-to-rail output buffers and is guaranteed monotonic over the specified range.
Feature Summary
- Dual 8-bit DACs with integrated 4.096V precision reference
- SPI/MICROWIRE compatible 3-wire serial interface
- Rail-to-rail output buffers with guaranteed monotonicity
- Power-on reset to mid-scale in internal reference mode
Applications
- Mobile communications
- Process control and industrial automation
- Automatic test equipment
- Portable 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 H-grade automotive temperature range (-40°C to 125°C) aligns with the environmental specifications of the target application before procurement.
Selection Notes
Select this component when a dual-channel DAC with an integrated high-accuracy reference is required in a compact 8-lead TSOT-23 package. Ensure the system supply voltage remains within the 4.5V to 5.5V range mandated by the HI series full-scale output specification. Consider the 8-bit resolution if lower data throughput is acceptable compared to the 10 or 12-bit variants.
Part Context
This part belongs to the LTC2632 family of dual DACs available in various resolutions (8, 10, and 12 bits) and accuracy grades. The 'H' designation indicates the automotive grade version with a wider operating temperature range compared to the commercial 'C' grade. The 'I' suffix specifies the power-on reset behavior to mid-scale when using the internal reference.
Replacement Considerations
Direct replacements within the same family include other LTC2632 variants with different resolutions or reset behaviors, such as LTC2632CTS8-HI12#TRPBF for higher resolution or LTC2632CTS8-LZ8#TRPBF for zero-scale reset. Verify pin compatibility and electrical parameter alignment when substituting.
