LTC2631CTS8-HZ10#TRPBF

Overview

The LTC2631CTS8-HZ10#TRPBF is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It integrates a precision reference with a temperature coefficient of 10ppm/°C and operates within a supply voltage range of 4.5V to 5.5V. The device features a rail-to-rail output buffer, guaranteed monotonicity, and a 2-wire I²C-compatible serial interface supporting clock rates up to 400kHz. It includes a power-on reset circuit that defaults the output to zero-scale upon power-up. The component is housed in an 8-lead TSOT-23 package and is rated for commercial operating temperatures from 0°C to 70°C.

Feature Summary

• 10-Bit Resolution with ±1 LSB Maximum Integral Nonlinearity (INL)
• Integrated 10ppm/°C Reference providing 4.096V Full-Scale Output
• I²C Interface with Fast Mode Support (400kHz Clock Rate)
• Power-On Reset to Zero-Scale Configuration

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive Systems

Procurement Notes

Verify the specific suffix 'HZ10' confirms the 10-bit resolution, zero-scale power-on reset behavior, and 4.096V full-scale voltage derived from the internal reference. Confirm the 'C' grade designation matches the required commercial temperature range of 0°C to 70°C for the application environment.

Selection Notes

Select this part when a compact 10-bit DAC is required with a fixed 4.096V output span and strict zero-state initialization. Ensure the system supply voltage remains between 4.5V and 5.5V, as lower voltages are not supported by the H-grade internal reference configuration. Consider the LTSOT-23 package constraints for thermal management and board space.

Part Context

This component belongs to the LTC2631 family of single-channel DACs. Variants within the family differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), power-on reset state (zero or mid-scale), and temperature grade (Commercial, Industrial, or Automotive). The CTS8-HZ10 variant specifically combines the H-grade voltage reference with the Z reset option.
