Overview
The LTC2632HTS8-LX12 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 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. Key specifications include a maximum integral nonlinearity (INL) error of ±2.5LSB, rail-to-rail output buffers, and a power-on reset function that initializes the outputs to mid-scale when operating in external reference mode.
Feature Summary
- Dual 12-bit DACs with integrated 2.5V precision reference (10ppm/°C drift)
- SPI/MICROWIRE compatible 3-wire serial interface with 50MHz clock rate
- Power-on reset to mid-scale in external reference mode
- Rail-to-rail output buffers with guaranteed monotonicity
Applications
- Mobile communications systems
- Process control and industrial automation
- Automatic test equipment
- Portable battery-powered equipment
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm availability and lead times. Ensure the selected variant matches the required power-on reset behavior and reference configuration for the target application design.
Selection Notes
Select this component when a dual-channel 12-bit DAC with an internal 2.5V reference is required in a compact TSOT-23 package. The LX suffix indicates mid-scale reset in external reference mode; choose LZ for zero-scale reset or LI for mid-scale reset in internal reference mode if those behaviors are preferred.
Part Context
This part belongs to the LTC2632 family of dual DACs, which offers various combinations of resolution (8, 10, 12-bit), accuracy grades, and power-on reset options. The HTS8 designation specifies the automotive temperature grade (-40°C to 125°C) and the 8-lead TSOT-23 package type.
Replacement Considerations
Direct replacements within the same family include LTC2632HTS8-LI12 (mid-scale reset, internal ref) and LTC2632HTS8-LZ12 (zero-scale reset, internal ref). Verify pin compatibility and reset behavior differences before substitution.
