LTC2632CTS8-LZ10

Overview

The LTC2632CTS8-LZ10 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 2.5V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 2.7V to 5.5V and utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. It includes rail-to-rail output buffers, double-buffered data latches, and a power-on reset circuit that clears outputs to zero-scale upon initialization.

Feature Summary

• Dual 10-bit resolution with guaranteed monotonicity
• Integrated 2.5V full-scale reference with ±10ppm/°C drift
• Power-on reset to zero-scale in internal reference mode
• 3-wire serial interface supporting SCK frequencies up to 50MHz

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment

Procurement Notes

Verify the specific ordering suffix for package type and tape/reel configuration against official documentation. Confirm availability through designated sales channels as distribution status may vary by region. Ensure compatibility with system voltage requirements before procurement.

Selection Notes

Select this model for applications requiring a 2.5V full-scale range and zero-scale power-on reset behavior. The 10-bit resolution offers a balance between accuracy and speed. Verify that the operating temperature range meets the commercial specification requirements of 0°C to 70°C.

Part Context

This component belongs to the LTC2632 family of dual DACs available in 8-, 10-, and 12-bit resolutions. Variants differ by full-scale voltage (2.5V or 4.096V), power-on reset behavior (zero or mid-scale), and accuracy grade. The LTS8 designation indicates the 8-lead TSOT-23 package format.

Replacement Considerations

Check for alternative part numbers within the LTC2632 series that match the required resolution, reset state, and full-scale voltage. Ensure any substitute maintains compatibility with the 3-wire serial interface timing and voltage levels.
