LTC2632CTS8-HI10#TRPBF

Overview

The LTC2632CTS8-HI10#TRPBF is a dual 10-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 double-buffered data latches and a power-on reset circuit that sets the output to mid-scale in internal reference mode upon power-up.

Feature Summary

• Dual 10-bit DACs with rail-to-rail output buffers
• Integrated 4.096V reference with ±10ppm/°C drift
• SPI/MICROWIRE compatible 3-wire serial interface
• 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 indicates a tape and reel quantity of 2,500 pieces. Confirm the C grade corresponds to the commercial temperature range of 0°C to 70°C. Ensure the HI designation matches the required 4.5V to 5.5V supply operation and 4.096V full-scale output. Cross-reference the exact part number with manufacturer documentation to confirm availability and lead times.

Selection Notes

Select this component when a dual-channel DAC with high accuracy and low drift is required within a compact TSOT-23 package. The HI variant is suitable for applications requiring a 4.096V full-scale range, necessitating a minimum supply voltage of 4.5V. The 10-bit resolution offers a balance between performance and data throughput. Verify that the system can accommodate the mid-scale power-on reset behavior if zero-scale initialization is critical.

Part Context

This part belongs to the LTC2632 family, which includes various combinations of resolution (8, 10, 12 bits), full-scale voltages (2.5V or 4.096V), and power-on reset options. The CTS8 designation specifies the commercial temperature grade and the 8-lead TSOT-23 package. The HI suffix indicates the 4.096V internal reference configuration, while I denotes the mid-scale power-on reset mode.

Replacement Considerations

Direct replacements within the same family include other LTC2632 variants with different resolutions or reset modes. For identical electrical characteristics but different packaging, check for equivalent parts in MSOP or DFN packages if available. Ensure any substitute supports the 4.5V minimum supply voltage and 4.096V full-scale output requirement.
