LTC2633CTS8-HZ12#TRMPBF

Overview

The LTC2633CTS8-HZ12#TRMPBF is a dual 12-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 4.096V and operates on a single 4.5V to 5.5V supply. The device 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 ±1.5 LSB, a settling time of 4.7µs at 5V, and a supply current of 0.5mA at 5V. It incorporates a power-on reset circuit that defaults outputs to zero-scale.

Feature Summary

• Dual 12-bit resolution with rail-to-rail output buffers
• Integrated 4.096V precision reference with ±10ppm/°C drift
• Maximum INL error of ±1.5 LSB for high accuracy
• Power-on reset to zero-scale for consistent initialization

Applications

• Mobile communications systems
• Process control and industrial automation
• Power supply margining
• Portable equipment
• Automotive applications

Procurement Notes

Verify the #TRMPBF suffix indicates a 500-unit tape and reel packaging configuration. Confirm the C temperature grade corresponds to the commercial range of 0°C to 70°C. Ensure the H code denotes the automotive temperature grade if operation beyond this range is required. Check for lead-free compliance documentation as specified by the PBF designation.

Selection Notes

Select this part when a 4.096V full-scale output is required with an internal reference. The H-grade variant supports a supply voltage range of 4.5V to 5.5V. Choose the Z reset code if zero-scale initialization upon power-up is necessary. Verify that the I²C address configuration via the CA0 pin aligns with system bus requirements.

Part Context

This component belongs to the LTC2633 family of dual DACs. Variants differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), and power-on reset behavior. The LTS8 package identifies the 8-lead ThinSOT form factor. The A electrical grade specifies the tighter ±1.5 LSB INL performance compared to the standard ±2.5 LSB grade.
