Overview
The LTC2632CTS8-LX12#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 reference providing a 2.5V full-scale output with 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. This specific variant includes a power-on reset function that sets the output to mid-scale when operating in external reference mode.
Feature Summary
- Dual 12-bit DACs with rail-to-rail output buffers and guaranteed monotonicity
- Integrated 2.5V full-scale reference with 10ppm/°C drift
- Power-on reset to mid-scale in external reference mode
- 3-wire serial interface with SCK frequencies up to 50MHz
Applications
- Mobile communications systems
- Process control and industrial automation
- Automatic test equipment
- Portable battery-powered equipment
Procurement Notes
Verify the complete part number including the #TRPBF suffix to confirm tape and reel packaging specifications. Confirm that the LX suffix requirement for external reference mid-scale reset aligns with system initialization needs. Ensure the 2.7V to 5.5V supply range matches the target application voltage rails before procurement.
Selection Notes
Select this component if a dual-channel DAC with integrated precision reference is required in a compact TSOT-23 footprint. The LX suffix is critical for designs requiring mid-scale initialization during external reference operation. For applications needing zero-scale power-up, consider the LZ suffix variants instead.
Part Context
This part belongs to the LTC2632 family of dual DACs available in 8-, 10-, and 12-bit resolutions. The 'L' designation indicates a 2.5V internal full-scale range, distinguishing it from the 'H' series which offers 4.096V. The 'CTS8' indicates the commercial temperature grade and TSOT-23 package type.
Replacement Considerations
Direct pin-compatible substitutes within the same family include LTC2632CTS8-LI12#TRPBF (internal reference reset) and LTC2632CTS8-LZ12#TRPBF (zero-scale reset). Cross-family replacements require verification of interface compatibility and supply voltage ranges.
