LTC2634CMSE-HMI10#TRPBF

Overview

The LTC2634CMSE-HMI10#TRPBF is a quad 10-bit voltage output digital-to-analog converter (DAC) in a 10-lead MSOP package. It features an integrated precision reference providing a 4.096V full-scale output and operates from a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the temperature range, and double-buffered data latches. Communication occurs via a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. Power-on reset defaults to mid-scale in internal reference mode.

Feature Summary

• Quad 10-bit DACs with integrated 4.096V precision reference
• Rail-to-rail output buffers with ultralow crosstalk (2.4nV•s)
• 3-wire SPI/MICROWIRE serial interface operating up to 50MHz
• Power-on reset to mid-scale in internal reference mode

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging containing 2,500 pieces. Confirm the MSE package designation corresponds to the 10-lead MSOP form factor. Ensure the H grade matches the required 4.5V to 5.5V supply voltage range for the 4.096V full-scale output configuration.

Selection Notes

Select this part when four independent 10-bit channels are required with a fixed 4.096V internal reference. The CMSE suffix denotes the commercial temperature range (0°C to 70°C). Verify that the system power supply remains within the 4.5V to 5.5V window to ensure specified performance levels for linearity and settling time.

Part Context

This component belongs to the LTC2634 family of quad DACs available in 8-, 10-, and 12-bit resolutions. Variants exist with 2.5V or 4.096V internal references and different power-on reset behaviors. The MSE package variant offers a compact footprint compared to the 16-lead QFN option while maintaining identical electrical characteristics for the same resolution and reference grade.

Replacement Considerations

LTC2634IMSE-HMI10#PBF: Identical electrical specifications and pinout; differs only in package quantity (tube vs. tape and reel).
