LTC2630AISC6-LM12#TRPBF

Overview

The LTC2630AISC6-LM12#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 2.5V and operates within a supply voltage range of 2.7V to 5.5V. The device utilizes a 3-wire SPI/Microwire compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a typical supply current of 180µA at 3V, and a power-down mode consuming 1.8µA maximum. It incorporates double-buffered data latches and a power-on reset circuit configured to initialize the output to mid-scale.

Feature Summary

• 12-Bit Resolution with ±1 LSB Maximum INL
• Integrated Precision Reference (2.5V Full Scale)
• Rail-to-Rail Output Buffer
• Power-On Reset to Mid-Scale

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive

Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature grade and package configuration. Confirm that the internal reference voltage matches the system requirements for the intended application environment.

Selection Notes

Select this component when a compact 6-lead SC70 package is required alongside high DC accuracy. Ensure the operating supply voltage falls within the 2.7V to 5.5V range and that the mid-scale power-on reset behavior aligns with downstream circuit safety constraints.

Part Context

This part belongs to the LTC2630 family of rail-to-rail DACs. The 'A' designation indicates an enhanced accuracy grade with a maximum INL of ±1 LSB, distinguishing it from standard grades which may exhibit higher nonlinearity errors.

Replacement Considerations

Direct pin-compatible replacements within the same series include LTC2630CISC6-LM12#TRPBF and LTC2630HISC6-LM12#TRPBF, differing primarily in operating temperature ranges.
