LTC2633CTS8-HZ10#TRMPBF

Overview

The LTC2633CTS8-HZ10#TRMPBF is a dual 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in an 8-lead TSOT-23 package. 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 communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a typical supply current of 0.4mA at 3V, and rail-to-rail output buffers that are guaranteed monotonic over the commercial temperature range of 0°C to 70°C.

Feature Summary

• Dual 10-bit DACs with integrated 2.5V precision reference (10ppm/°C drift)
• I²C interface with selectable internal or external reference input
• Power-on reset configured to zero-scale for consistent initialization
• Rail-to-rail output buffers with ±1 LSB maximum INL error

Applications

• Mobile communications systems
• Process control and industrial automation
• Portable equipment requiring low power consumption
• Automotive electronics
• Power supply margining applications

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration, distinct from the standard 2500-unit reel. Confirm the C-grade designation aligns with the required 0°C to 70°C operating temperature range for the target application environment. Ensure compatibility with the 2.7V to 5.5V supply voltage constraints during system design validation.

Selection Notes

Select this part when a dual-channel solution with a fixed 2.5V internal reference is required within the commercial temperature grade. The HZ code specifies a zero-scale power-on reset, which is critical if downstream circuits must remain inactive during startup. Compare against the -HI10 variant if a 4.096V full-scale output or automotive temperature range (-40°C to 125°C) is necessary instead.

Part Context

This component belongs to the LTC2633 family of dual DACs, which offers various combinations of resolution (8-, 10-, or 12-bit), accuracy grades, and power-on reset behaviors. The LTS8 package denotes the 8-lead ThinSOT form factor. The 'A' suffix typically denotes higher accuracy grades, but its absence here implies the standard performance level specified for the 10-bit resolution in this series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices directly for alternative components with matching pinouts, electrical specifications, and thermal characteristics.
