LTC2633CTS8-LO10#TRPBF

Overview

The LTC2633CTS8-LO10#TRPBF 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 operates on a single 2.7V to 5.5V supply. The device communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, rail-to-rail output buffers, and guaranteed monotonicity over the commercial temperature range of 0°C to 70°C. Upon power-up, the outputs reset to a high-impedance state.

Feature Summary

• Dual 10-bit DACs with integrated 2.5V precision reference (10ppm/°C drift)
• I²C interface with selectable standard (100kHz) or fast (400kHz) clock rates
• Power-on reset to high-impedance state for safe initialization
• Rail-to-rail output buffers with ±1 LSB maximum INL error

Applications

• Portable equipment requiring low power consumption
• Process control and industrial automation systems
• Mobile communications devices
• Automotive electronic applications

Procurement Notes

Verify the specific ordering suffix LO10#TRPBF against the manufacturer's current product selection guide to confirm availability and exact pinout configuration. Ensure the commercial temperature grade (C) meets the operational requirements of the target environment, as this part is not rated for the extended automotive range.

Selection Notes

Select this component when a dual-channel, low-pin-count DAC with an internal reference is required for 10-bit resolution applications. The LO suffix indicates a high-impedance power-on reset, which is critical if downstream circuits must remain inactive during system startup. Compare against the HI variant if a 4.096V full-scale output and higher supply voltage range are needed instead.

Part Context

This part belongs to the LTC2633 family of dual DACs, which also includes 8-bit and 12-bit variants. The 'C' designation specifies the commercial temperature range (0°C to 70°C), distinguishing it from the 'H' grade used for automotive applications (-40°C to 125°C). The 'TS8' indicates the 8-lead ThinSOT package type.

Replacement Considerations

Direct replacements within the same family include the LTC2633CTS8-LI10#TRPBF (mid-scale reset) or LTC2633CTS8-LZ10#TRPBF (zero-scale reset). For different resolutions, consider the LTC2633CTS8-LO08#TRPBF (8-bit) or LTC2633CTS8-LO12#TRPBF (12-bit), ensuring the power-on reset behavior matches the system design.
