Overview
The LTC2637IMS-HMX8#TRPBF is an octal 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a high-accuracy internal reference with a temperature coefficient of 10ppm/°C, providing a full-scale output of 4.096V. The device operates on a single supply voltage ranging from 4.5V to 5.5V and communicates via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It incorporates double-buffered data latches and a power-on reset circuit configured to reset to mid-scale in external reference mode. The component is housed in a 16-lead MSOP package.
Feature Summary
- Octal architecture with 8 independent 8-bit DAC channels
- Integrated 4.096V precision reference with ±10ppm/°C drift
- I2C-compatible serial interface with selectable slave addresses
- Power-on reset to mid-scale for external reference configurations
Applications
- Process control and industrial automation systems
- Portable battery-powered equipment
- Automotive electronic modules
- Optical networking infrastructure
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging containing 2500 units. Confirm the H-grade designation ensures operation within the –40°C to +125°C automotive temperature range. Ensure the IMS package type matches the target PCB footprint requirements for the 16-lead MSOP configuration.
Selection Notes
Select this part when eight isolated analog outputs are required from a single IC. The H-grade variant is necessary for applications requiring operation above 85°C. Verify that the system supply voltage remains between 4.5V and 5.5V to meet electrical specifications. Consider the external reference mode if the application requires a full-scale output different from the internal 4.096V setting.
Part Context
This component belongs to the LTC2637 family, which includes 12-bit, 10-bit, and 8-bit variants. The 'H' suffix denotes the automotive temperature grade, while 'MS' specifies the 16-lead MSOP package. The 'MX' power-on reset option configures the device to initialize to mid-scale when using an external reference voltage source.
Replacement Considerations
LTC2637IMS-HMI8#TRPBF offers identical electrical characteristics but resets to mid-scale in internal reference mode instead of external reference mode.
