LTC2630ISC6-LM10#TRPBF

Overview

The LTC2630ISC6-LM10#TRPBF 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 voltage ranging from 2.7V to 5.5V. The device includes a rail-to-rail output buffer and is guaranteed monotonic 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 with the internal reference active.

Feature Summary

• Integrated 10ppm/°C precision reference with 2.5V full-scale output
• Rail-to-rail output buffer guaranteed monotonic over temperature
• 3-wire SPI/MICROWIRE serial interface supporting up to 50MHz clock
• Power-on reset option to mid-scale for consistent initialization

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel packaging quantity of 2,500 pieces. Confirm the 'I' grade designation corresponds to the industrial temperature range of –40°C to 85°C. Ensure the 'LM' suffix correctly specifies the mid-scale power-on reset behavior and 2.5V full-scale voltage configuration before finalizing procurement.

Selection Notes

Select this component when a single-channel DAC in a compact 6-lead SC70 package is required. Choose the LM variant if a mid-scale power-on reset state is preferred over zero-scale. Verify that the system supply voltage falls within the 2.7V to 5.5V range suitable for the -L series. Consider the 10-bit resolution and ±1 LSB INL specification against application accuracy requirements.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 12-, 10-, and 8-bit resolutions. The family shares identical pinouts and serial interface protocols across variants, differing primarily in resolution, power-on reset behavior, and full-scale voltage settings determined by the internal reference or supply mode.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2630ISC6-HM10#TRPBF (4.096V full-scale) or LTC2630ISC6-LZ10#TRPBF (zero-scale reset). Cross-family replacements like the LTC2634 require different packages and interfaces.
