LTC2630HSC6-HM12#TRMPBF

Overview

The LTC2630HSC6-HM12#TRMPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference yielding a full-scale output of 4.096V and operates within a supply voltage range of 4.5V to 5.5V. 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 specifications include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 4.8µs at 5V, and a typical supply current of 200µA. It incorporates double-buffered data latches and power-on reset options.

Feature Summary

• Integrated precision reference with 10ppm/°C temperature coefficient for 4.096V full-scale output
• SPI/MICROWIRE compatible 3-wire serial interface with SCK frequencies up to 50MHz
• Double-buffered data latches allowing simultaneous updates of multiple DACs
• Power-on reset circuit configurable to zero or mid-scale output

Applications

• Mobile communications systems
• Process control and industrial automation instrumentation
• Automatic test equipment (ATE)
• Portable battery-powered equipment
• Automotive electronic modules

Procurement Notes

Verify the specific suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration as defined in the manufacturer's ordering information. Confirm that the H-grade designation matches the required -40°C to +125°C automotive temperature operating range for the target application environment.

Selection Notes

Select this component when a compact 6-lead SC70 package is required alongside high accuracy (±1 LSB INL). Ensure the system supply voltage remains between 4.5V and 5.5V to support the 4.096V internal reference mode. Consider the power-down current of 5µA maximum if low standby consumption is critical for the design.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The 'H' suffix denotes the automotive temperature grade (-40°C to +125°C), while 'HM' specifies the mid-scale power-on reset behavior and 4.096V full-scale voltage derived from the internal reference.

Replacement Considerations

Compatible substitutes within the same family include the LTC2630HSC6-LM12#TRMPBF for 2.5V full-scale applications or the LTC2630HSC6-HZ12#TRMPBF for zero-scale power-on reset requirements. Verify pin compatibility and thermal characteristics when substituting.
