Overview
The LTC2633AHTS8-LO12#TRPBF is a dual 12-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 operates on a single 2.7V to 5.5V supply. The device utilizes 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, rail-to-rail output buffers, and guaranteed monotonicity over the –40°C to 125°C temperature range. The power-on reset configuration sets outputs to high impedance.
Feature Summary
- Dual 12-bit DACs with integrated 2.5V precision reference (10ppm/°C drift)
- Maximum INL error of ±1.5 LSB for enhanced accuracy
- Power-on reset to High Impedance state for safe initialization
- Rail-to-rail output buffers with 2.7V to 5.5V single-supply operation
Applications
- Mobile Communications
- Process Control and Industrial Automation
- Power Supply Margining
- Portable Equipment
- Automotive Systems
Procurement Notes
Verify the specific ordering suffix #TRPBF corresponds to the 2,500-piece tape and reel packaging format as defined in the manufacturer's documentation. Confirm that the LO12 designation matches the required high-impedance power-on reset behavior and 12-bit resolution for the target application design.
Selection Notes
Select this component when a dual-channel DAC with high accuracy (±1.5 LSB INL) and low-power consumption is required. The LO12 variant is specifically chosen for applications necessitating a high-impedance output state upon power-up to prevent unintended signal generation during system initialization.
Part Context
This part belongs to the LTC2633 family of dual DACs available in various resolutions (8-, 10-, and 12-bit) and accuracy grades. The 'A' grade denotes the improved linearity specification compared to standard parts. The TSOT-23 package provides a compact solution for space-constrained designs requiring integrated references.
Replacement Considerations
Direct replacements within the same family include LTC2633AHTS8-LI12#TRPBF or LTC2633AHTS8-LZ12#TRPBF, depending on whether mid-scale or zero-scale power-on reset behavior is acceptable instead of high impedance.
