LTC2630AISC6-HM12

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 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 settling time of 4.8µs at 5V, and a typical supply current of 200µA. It is housed in a compact 6-lead SC70 package and supports power-down modes for low-power applications.

Feature Summary

• Integrated Precision Reference: Provides a stable 4.096V full-scale output with a temperature coefficient of 10ppm/°C.
• High Accuracy: Guaranteed monotonic operation with a maximum INL error of ±1 LSB for the A-grade device.
• Low Power Consumption: Typical supply current of 200µA at 5V, reducing to 1.8µA maximum in power-down mode.
• Compact Packaging: Available in a tiny 6-lead SC70 surface-mount package.

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel quantity. Confirm that the 'I' grade corresponds to the industrial temperature range of –40°C to 85°C. Ensure the 'HM12' designation matches the required mid-scale power-on reset and 4.096V full-scale voltage configuration.

Selection Notes

Select this component when a single-channel DAC with high accuracy (±1 LSB INL) and a compact SC70 footprint is required. Choose the HM variant if a mid-scale power-on reset is necessary for system initialization. Verify that the application supply voltage falls within the 4.5V to 5.5V range required for the H-grade internal reference operation.

Part Context

This part belongs to the LTC2630 family of rail-to-rail DACs. The 'A' denotes the electrical grade with ±1 LSB max INL, 'I' indicates the industrial temperature range, 'SC6' specifies the 6-lead SC70 package, 'H' sets the 4.096V full-scale output, 'M' configures the mid-scale power-on reset, and '12' defines the 12-bit resolution.
