LTC2630ISC6-HM12#TRPBF

Overview

The LTC2630ISC6-HM12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference yielding a 4.096V full-scale output and operates within a 4.5V to 5.5V supply range. The device features a rail-to-rail output buffer, guaranteed monotonicity, and an SPI/MICROWIRE compatible 3-wire serial interface supporting clock rates up to 50MHz. Key electrical parameters include a maximum integral nonlinearity of ±1 LSB, a settling time of 4.8µs at 5V, and a typical supply current of 200µA. It includes power-on reset functionality set to mid-scale and double-buffered data latches.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C temperature coefficient
• SPI/MICROWIRE compatible 3-wire serial interface with 50MHz clock rate
• Rail-to-rail output buffer with ±1 LSB maximum INL error
• Power-on reset to mid-scale option with 200µA typical supply current

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a 2,500-piece tape and reel packaging configuration. Confirm that the 'I' grade designation matches the required -40°C to 85°C operating temperature range for the application environment. Ensure the 4.5V minimum supply voltage requirement aligns with the system power architecture.

Selection Notes

Select this part when a 4.096V internal reference is required alongside a compact SC70-6 package. The 'HM' suffix specifies a mid-scale power-on reset state; choose 'HZ' if zero-scale initialization is preferred. Verify that the 4.5V to 5.5V supply constraint fits the design, as the 'L' variant supports lower voltages but offers only 2.5V full scale.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 12-, 10-, and 8-bit resolutions. The family shares a common pinout and interface protocol but varies by resolution, reset behavior, and integrated reference voltage. The 'H' grade specifically denotes the 4.096V full-scale capability requiring a higher minimum supply voltage compared to the 'L' grade variants.
