Overview
The LTC2634CMSE-HMX12#TRPBF is a quad 12-bit voltage-output digital-to-analog converter (DAC) in a 10-lead MSOP package. It features an integrated precision reference with a full-scale output of 4.096V and operates from a 4.5V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the -40°C to 85°C temperature range, and a maximum integral nonlinearity error of ±2.5 LSB. Communication occurs via a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. Power-on reset defaults to mid-scale in external reference mode.
Feature Summary
- Quad 12-bit resolution with integrated 4.096V precision reference
- Rail-to-rail output buffers with ultralow crosstalk (2.4nV•s)
- SPI/MICROWIRE compatible 3-wire serial interface
- Power-on reset to mid-scale in external reference mode
Applications
- Mobile communications
- Process control and industrial automation
- Automatic test equipment
- Portable equipment
Procurement Notes
Verify the specific suffix #TRPBF indicates a tape and reel packaging configuration containing 2,500 pieces. Confirm the MSE designation corresponds to the 10-lead MSOP package type. Ensure the H-grade specification aligns with the required operating temperature range for the target application environment.
Selection Notes
Select this part when a quad DAC configuration with 12-bit accuracy and a 4.096V internal reference is required. The H-grade variant supports a supply voltage range of 4.5V to 5.5V. Choose the MSE package for applications requiring a 10-lead MSOP footprint rather than the 16-lead QFN option.
Part Context
This component belongs to the LTC2634 family of quad DACs available in 12-, 10-, and 8-bit resolutions. The CMSE prefix identifies the commercial temperature grade (-40°C to 85°C), the MSE package type, and the H-grade full-scale voltage capability. The HMX12 suffix specifies the 12-bit resolution and mid-scale power-on reset behavior in external reference mode.
Replacement Considerations
LTC2634IMSE-HMX12#TRPBF: Industrial temperature grade (-40°C to 85°C). LTC2634HUSE-HMX12#TRPBF: Automotive temperature grade (-40°C to 125°C). LTC2634CUD-HMX12#TRPBF: 16-lead QFN package instead of MSOP.
