LTC2633CTS8-LI10#TRMPBF

Overview

The LTC2633CTS8-LI10#TRMPBF is a dual-channel, 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision internal reference with a temperature coefficient of ±10ppm/°C and operates on a single supply voltage ranging from 2.7V to 5.5V. The device features rail-to-rail output buffers and communicates via a standard 2-wire I²C-compatible serial interface supporting clock rates up to 400kHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a typical supply current of 0.4mA at 3V, and a settling time of 4.0µs for 10-bit resolution. The component is housed in an 8-lead TSOT-23 package and is guaranteed monotonic over the commercial operating temperature range of 0°C to 70°C.

Feature Summary

• Dual 10-bit DAC channels with integrated ±10ppm/°C precision reference
• Rail-to-rail output buffers with ±1 LSB maximum INL error
• 2-wire I²C interface supporting Standard (100kHz) and Fast (400kHz) modes
• Power-on reset configured to mid-scale in internal reference mode

Applications

• Mobile communications systems
• Process control and industrial automation
• Portable equipment requiring low power consumption

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration. Confirm that the C-grade designation aligns with the required commercial temperature range of 0°C to 70°C for the target application environment. Ensure the LI10 code corresponds to the intended mid-scale power-on reset behavior and 10-bit resolution.

Selection Notes

Select this part when a compact dual-channel solution with integrated reference is required. The 10-bit resolution offers a balance between accuracy and speed, with a 4.0µs settling time. The 2.7V to 5.5V supply range allows compatibility with various logic levels. Consider the external reference option if higher full-scale voltages or different reference sources are needed, as this variant uses the internal 2.5V full-scale reference.

Part Context

This component belongs to the LTC2633 family, which includes 8-bit, 10-bit, and 12-bit variants. The 'L' suffix denotes a 2.5V full-scale output capability, while 'H' variants support 4.096V. The 'A' grade indicates tighter linearity specifications (±1.5 LSB INL), whereas the base model has ±2.5 LSB INL. The 'TS8' package refers to the 8-lead ThinSOT-23 form factor.

Replacement Considerations

Direct replacements within the same family include LTC2633CTS8-LI12#TRMPBF for 12-bit resolution or LTC2633CTS8-LI8#TRMPBF for 8-bit resolution. Verify pin compatibility and software register mapping, as the I²C command structure remains consistent across the family.
