Overview
The LTC2634CUD-LMX10#TRPBF is a quad 10-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 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. Key specifications include rail-to-rail output buffers, guaranteed monotonicity over the operating temperature range, and ultralow crosstalk between DACs (2.4nV•s). This specific variant includes power-on reset to mid-scale in external reference mode and is housed in a 16-lead QFN package.
Feature Summary
- Quad 10-bit resolution with ±1 LSB maximum INL error
- Integrated 10ppm/°C precision reference providing 2.5V full-scale output
- Power-on reset configured to mid-scale in external reference mode
- Ultralow DAC-to-DAC crosstalk of 2.4nV•s typical
Applications
- Mobile communications systems
- Process control and industrial automation
- Automatic test equipment
- Portable battery-powered equipment
- Automotive applications
Procurement Notes
Verify the ordering suffix #TRPBF indicates lead-free construction and tape-and-reel packaging containing 2,500 pieces. Confirm the C temperature grade matches the required commercial range of 0°C to 70°C for the specific application environment.
Selection Notes
Select this part when a quad DAC configuration with 10-bit accuracy is required. The L suffix denotes a 2.5V internal reference suitable for 2.7V to 5.5V supplies. Choose the MX suffix if mid-scale initialization in external reference mode is necessary upon power-up.
Part Context
This component belongs to the LTC2634 family, which offers 8-, 10-, and 12-bit resolutions in 16-lead QFN and 10-lead MSOP packages. The family shares common architectural features including rail-to-rail outputs and low power consumption, differentiated by resolution, reference voltage options, and power-on reset behaviors.
Replacement Considerations
Direct substitutes within the same package and pinout include other LTC2634 variants such as LTC2634CUD-LMI10#TRPBF or LTC2634CUD-LZ10#TRPBF, depending on the required power-on reset behavior and reference mode.
