LTC2630ISC6-LM8#TRMPBF

Overview

The LTC2630ISC6-LM8#TRMPBF is a single-channel, 8-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 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 ±0.5 LSB, a settling time of 3.2µs at 3V, and a typical supply current of 180µA at 3V in internal reference mode.

Feature Summary

• Integrated 2.5V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer with guaranteed monotonicity
• 3-wire SPI/MICROWIRE serial interface supporting 50MHz clock
• Power-on reset to mid-scale output

Applications

• Mobile communications
• Process control and industrial automation
• Portable equipment

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel packaging configuration. Confirm that the 'I' grade designation matches the required industrial operating temperature range of –40°C to 85°C for the target application environment.

Selection Notes

Select this part when an 8-bit resolution is sufficient for the application's accuracy requirements. Ensure the system supply voltage remains between 2.7V and 5.5V. Choose this variant if a mid-scale power-on reset state is preferred over zero-scale initialization. Verify that the SC70-6 package footprint aligns with the PCB layout constraints.

Part Context

This component belongs to the LTC2630 family of single DACs available in 8-, 10-, and 12-bit resolutions. The 'LM8' designation specifies the 8-bit resolution, 2.5V full-scale internal reference, and mid-scale power-on reset behavior. The 'SC6' indicates the 6-lead SC70 package type, while 'I' denotes the industrial temperature grade.

Replacement Considerations

Direct replacements within the same family include LTC2630ISC6-LZ8#TRMPBF for zero-scale reset or LTC2630ISC6-HM8#TRMPBF for 4.096V full-scale output. Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
