Overview
The LTC2634HMSE-HMI8#TRPBF is a quad 8-bit voltage output digital-to-analog converter (DAC) from Analog Devices, housed in a 10-lead MSOP package. It features an integrated precision reference with a full-scale output of 4.096V and operates on a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers, double-buffered data latches, and an SPI/MICROWIRE compatible 3-wire serial interface supporting clock rates up to 50MHz. It guarantees monotonicity over the -40°C to 125°C temperature range and incorporates a power-on reset circuit that sets outputs to mid-scale.
Feature Summary
- Quad 8-bit DACs with integrated 4.096V precision reference
- Rail-to-rail output buffers with guaranteed monotonicity
- SPI/MICROWIRE compatible 3-wire serial interface
- Power-on reset to mid-scale in internal reference mode
Applications
- Process control and industrial automation
- Portable equipment
- Automotive systems
Procurement Notes
Verify the specific ordering suffix #TRPBF indicates a tape and reel quantity of 2,500 pieces. Confirm the H-grade designation corresponds to the automotive temperature range of -40°C to 125°C. Ensure the MSE package type matches the required 10-lead MSOP footprint for the design.
Selection Notes
Select this part when four independent 8-bit channels are required with a fixed 4.096V full-scale range. The H-grade variant is necessary for applications operating between -40°C and 125°C. Verify that the 4.5V minimum supply voltage aligns with the system power rails, as the L-grade variant supports lower voltages down to 2.7V.
Part Context
This component belongs to the LTC2634 family, which offers various resolutions (8, 10, 12 bits), packages (QFN, MSOP), and temperature grades (C, I, H). The HMSE suffix specifically denotes the H-grade temperature range, MSOP package, mid-scale internal reset, and 8-bit resolution.
Replacement Considerations
Direct substitutes within the same family include LTC2634IMSE-HMI8#TRPBF for industrial temperature range or LTC2634HMSE-LMI8#TRPBF for different reset behavior. Cross-package replacements like QFN variants require schematic and layout adjustments.
