LTC2630CSC6-LM10#TRMPBF

Overview

The LTC2630CSC6-LM10#TRMPBF is a single-channel, 10-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 on a single supply ranging from 2.7V to 5.5V. The device includes a rail-to-rail output buffer and guarantees monotonicity over temperature. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical parameters include a maximum integral nonlinearity (INL) of ±1 LSB, a typical settling time of 3.9µs at 3V, and a supply current of 180µA at 3V. The component is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated Precision Reference: Provides a stable 2.5V full-scale output with a low drift of 10ppm/°C.
• High Accuracy Linearity: Guaranteed monotonic operation with a maximum INL error of ±1 LSB for the 10-bit resolution.
• Low Power Consumption: Operates with a typical supply current of 180µA at 3V and supports power-down mode reducing current to 1.8µA maximum.
• Compact Packaging: Available in a tiny 6-lead SC70 surface-mount package suitable for space-constrained designs.

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, distinct from the standard 2,500-piece TR configuration. Confirm that the LM10 designation corresponds to the 10-bit resolution with mid-scale power-on reset and 2.5V internal reference. Ensure compatibility with the commercial temperature grade (0°C to 70°C) specified by the C suffix.

Selection Notes

Select this part when a single-channel DAC with 10-bit resolution and an integrated 2.5V reference is required. The LM suffix indicates a power-on reset to mid-scale; choose the LZ suffix if zero-scale reset is preferred. Verify that the system supply voltage falls within the 2.7V to 5.5V range. Consider the H-grade (-40°C to 125°C) or I-grade (-40°C to 85°C) variants if operation outside the commercial temperature range is necessary.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares common architectural features including the SC70 package, SPI interface, and integrated reference options. Variants differ primarily in resolution, power-on reset behavior (Mid-Scale vs. Zero), and full-scale voltage settings (2.5V vs. 4.096V).
