LTC2634CMSE-HZ12#TRPBF

Overview

The LTC2634CMSE-HZ12#TRPBF is a quad 12-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 2.5V and operates on a single 2.7V to 5.5V supply. The device includes rail-to-rail output buffers and guarantees monotonicity over the commercial temperature range of 0°C to 70°C. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. Power-on reset defaults to zero-scale.

Feature Summary

• Quad 12-bit resolution with ±2.5 LSB maximum integral nonlinearity error
• Integrated 10ppm/°C precision reference providing 2.5V full-scale output
• Rail-to-rail output buffers with ultralow crosstalk (2.4nV•s)
• Power-on reset configured to zero-scale for consistent initialization

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 tape and reel packaging containing 2,500 pieces. Confirm the MSE package designation corresponds to the 10-lead MSOP form factor. Ensure the C grade matches the required 0°C to 70°C operating temperature range for the target application environment.

Selection Notes

Select this part when four independent 12-bit DAC channels are required in a compact surface-mount package. The internal 2.5V reference eliminates external component requirements for gain setting. Verify that the 2.7V minimum supply voltage aligns with the system power architecture. Consider the H-grade variant if operation below 0°C or above 70°C is necessary.

Part Context

This component belongs to the LTC2634 family, which offers 8-, 10-, and 12-bit resolutions in both QFN and MSOP packages. The CMSE suffix denotes the Commercial temperature grade and MSOP package type. The HZ12 suffix specifies the 12-bit resolution and zero-scale power-on reset behavior with the internal reference.

Replacement Considerations

LTC2634IMSE-HZ12#PBF provides identical electrical specifications but covers the wider Industrial temperature range (-40°C to 85°C). LTC2634HUD-LMX12#PBF offers Automotive qualification and extended temperature range (-40°C to 125°C) with mid-scale reset. Package variations include the 16-lead QFN (UD) for applications requiring additional serial data output pins.
