Overview
The LTC2632CTS8-LI10#TRMPBF 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 a temperature coefficient of 10ppm/°C. The device operates on a single supply ranging from 2.7V to 5.5V and communicates via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. It includes rail-to-rail output buffers, guaranteed monotonicity, and a power-on reset function that sets outputs to mid-scale in internal reference mode upon startup.
Feature Summary
- Dual 10-bit DACs with integrated 2.5V full-scale reference
- Low drift reference with ±10ppm/°C temperature coefficient
- SPI/MICROWIRE compatible 3-wire serial interface
- Power-on reset to mid-scale in internal reference mode
Applications
- Mobile communications
- Process control and industrial automation
- Automatic test equipment
- Portable equipment
Procurement Notes
Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel configuration as defined in the manufacturer's documentation. Confirm the C-grade commercial temperature range (0°C to 70°C) aligns with system requirements. Ensure compatibility with the 2.7V to 5.5V supply voltage range specified for the LTC2632-L series.
Selection Notes
Select this component when a dual-channel DAC with a fixed 2.5V internal reference is required. The LI suffix denotes a mid-scale power-on reset behavior suitable for applications where downstream circuits must remain inactive or neutral during initialization. Verify that the 10-bit resolution meets the system accuracy needs, noting the maximum INL error of ±1LSB for this resolution grade.
Part Context
This part belongs to the LTC2632 family, which offers various combinations of resolution (8, 10, 12-bit), full-scale voltage (2.5V or 4.096V), and power-on reset options. The 'L' designation specifies the 2.5V full-scale variant operating from 2.7V to 5.5V, while 'H' variants support 4.096V full-scale but require a higher minimum supply voltage of 4.5V.
Replacement Considerations
Direct substitutes within the same family include LTC2632CTS8-LZ10#TRMPBF (zero-scale reset) or LTC2632CTS8-LI12#TRMPBF (12-bit resolution). Cross-family replacements may require verification of pin compatibility and reference voltage alignment.
