LTC2634IMSE-LMI10#TRPBF

Overview

The LTC2634IMSE-LMI10#TRPBF is a quad 10-bit voltage output digital-to-analog converter (DAC) from Analog Devices, housed in a 10-lead MSOP package. It features an integrated precision reference providing a 2.5V full-scale output and operates on a single 2.7V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the -40°C to 85°C industrial temperature range, and a power-on reset function that sets outputs to mid-scale in internal reference mode. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz.

Feature Summary

• Quad 10-bit resolution with ±1 LSB maximum Integral Nonlinearity (INL)
• Integrated 10ppm/°C precision reference yielding 2.5V full-scale output
• Rail-to-rail output buffers with ultralow crosstalk (2.4nV·s typical)
• Power-on reset to mid-scale in internal reference mode

Applications

• Mobile communications systems
• Process control and industrial automation
• Automatic test equipment
• Portable battery-powered equipment

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel quantity of 2,500 pieces. Confirm the IMSE designation corresponds to the Industrial temperature grade (-40°C to 85°C) and the MSE package type. Ensure compatibility with the required 2.7V to 5.5V supply voltage range for the L-grade variant.

Selection Notes

Select this part when a quad DAC configuration is required with a fixed 2.5V internal reference. The 'MI' suffix specifies a power-on reset to mid-scale, which is suitable if downstream circuits require a non-zero initial state. For applications needing zero-scale reset, consider the 'Z' suffix variants. The MSOP package is appropriate for space-constrained designs where QFN is not preferred.

Part Context

This component belongs to the LTC2634 family, which offers 12-, 10-, and 8-bit resolutions in both 16-lead QFN and 10-lead MSOP packages. The family shares common architectural features such as the 3-wire serial interface and low-power consumption, but varies in accuracy, reset behavior, and full-scale voltage options based on the specific suffix codes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pinout and electrical parameter compatibility before considering alternative quad DACs from other manufacturers.
