LTC2630ISC6-LM8

Overview

The LTC2630ISC6-LM8 is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision 2.5V reference and operates within a 2.7V to 5.5V supply range. The device features a rail-to-rail output buffer, SPI/Microwire compatible 3-wire serial interface, and double-buffered data latches. Key electrical parameters include a maximum integral nonlinearity (INL) of ±0.5 LSB, settling time of 3.2µs at 3V, and supply current of 180µA. It supports power-down mode with 1.8µA maximum current and includes power-on reset options.

Feature Summary

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

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive systems

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel packaging quantity. Confirm the temperature grade 'I' corresponds to the -40°C to +85°C operating range. Ensure compatibility with the SC-70-6 package dimensions for PCB layout.

Selection Notes

Select this part for applications requiring an 8-bit resolution DAC in a compact SC70 package. The LM suffix indicates a mid-scale power-on reset, suitable when downstream circuits are active during startup. Choose between internal reference or supply-as-reference modes based on system regulation requirements.

Part Context

This component belongs to the LTC2630 family of single-channel DACs. Variants differ by resolution (8, 10, 12-bit), full-scale voltage (2.5V or 4.096V), and power-on reset behavior (zero or mid-scale). The ISC6 designation specifies the Industrial temperature grade and SC70 package type.
