LTC2630AISC6-HM12#TRMPBF

Overview

The LTC2630AISC6-HM12#TRMPBF 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 rail-to-rail output buffer and supports SPI/MICROWIRE compatible 3-wire serial interfaces with clock rates up to 50MHz. Key electrical specifications 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 capable of sourcing/sinking up to 10mA
• SPI/MICROWIRE compatible 3-wire serial interface operating up to 50MHz

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration. Confirm that the 'I' temperature grade corresponds to the -40°C to +85°C operating range and the 'H' full-scale designation matches the required 4.096V output specification for the target application design.

Selection Notes

Select this component when a compact 6-lead SC70 package is required alongside high DC accuracy defined by ±1 LSB INL. Ensure the system supply voltage remains between 4.5V and 5.5V to support the internal 4.096V reference mode. Consider the 4.8µs settling time and 200µA active current consumption against available power budgets and signal update rate requirements.

Part Context

This part belongs to the LTC2630 family of single-channel DACs, which also includes 10-bit and 8-bit variants. The 'A' grade denotes the highest linearity performance within the series. Other suffixes in the family vary by temperature range (C, I, H), power-on reset behavior (M for mid-scale, Z for zero-scale), and full-scale voltage options (L for 2.5V, H for 4.096V).

Replacement Considerations

Direct pin-compatible replacements within the same package and interface include other LTC2630 variants such as LTC2630ISC6-HM12#TRPBF or LTC2630HSC6-HM12#TRMPBF, provided the temperature grade and packaging quantity meet the design constraints.
