LTC2630ACSC6-HM12#TRPBF

Overview

The LTC2630ACSC6-HM12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a full-scale output of 4.096V and operates within a supply voltage range of 4.5V to 5.5V. The device utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical characteristics include a maximum integral nonlinearity (INL) error 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

• 12-bit resolution with ±1 LSB maximum INL error
• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer guaranteed monotonic over temperature
• 3-wire SPI/MICROWIRE serial interface supporting up to 50MHz clock

Applications

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

Procurement Notes

Verify the specific suffix #TRMPBF indicates a 500-unit tape and reel packaging option, distinct from the standard 2500-unit reel. Confirm the 'H' grade designation corresponds to the automotive temperature range of –40°C to +125°C. Ensure the 'M' power-on reset configuration matches system initialization requirements for mid-scale output upon power-up.

Selection Notes

Select this component when a compact 6-lead SC70 package is required alongside high DC accuracy specified by the 'A' grade. Choose the 'H' variant if the application demands operation in extended temperature environments up to 125°C. Verify that the 4.5V minimum supply voltage aligns with the system's power rails, as lower voltage variants are available for 2.7V systems.

Part Context

This part belongs to the LTC2630 family of rail-to-rail DACs. The 'A' suffix denotes the highest accuracy grade with ±1 LSB INL, while 'HM12' specifies the 4.096V internal reference, mid-scale power-on reset, and 12-bit resolution. The device competes in the low-pin-count, high-integration DAC market segment.
