Overview
The LTC2633CTS8-LO12#TRPBF 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 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 electrical specifications include a maximum integral nonlinearity (INL) error of ±2.5 LSB, a supply current of 0.4mA at 3V, and guaranteed monotonicity over the operating temperature range.
Feature Summary
- Dual-channel 12-bit resolution with rail-to-rail output buffers
- Integrated 2.5V precision reference with 10ppm/°C drift
- I²C interface with selectable power-on reset to high impedance state
- Guaranteed monotonic operation across –40°C to 125°C temperature range
Applications
- Mobile communications systems
- Process control and industrial automation
- Power supply margining
- Portable equipment
- Automotive applications
Procurement Notes
Verify the specific ordering suffix #TRPBF corresponds to the 2,500-piece tape and reel packaging configuration as defined in the manufacturer's documentation. Confirm that the C-grade designation aligns with the required commercial temperature range for the target application environment.
Selection Notes
Select this part when a dual-channel DAC with a 2.5V internal reference and high-impedance power-on reset state is required. Ensure the system supply voltage remains within the 2.7V to 5.5V range specified for the L-series devices. Consider the ±2.5 LSB INL specification against application accuracy requirements.
Part Context
This component belongs to the LTC2633 family of dual DACs, which offers various combinations of resolution, reference voltage, and power-on reset behaviors. The LO12 variant specifically denotes the 12-bit resolution, 2.5V full-scale internal reference, and high-impedance output reset option.
Replacement Considerations
Direct replacements within the same family include LTC2633CTS8-LI12#TRPBF (mid-scale reset) or LTC2633CTS8-LZ12#TRPBF (zero-scale reset). Verify pin compatibility and I²C address configurations when substituting.
