LTC2630ISC6-LM12#TRMPBF

Overview

The LTC2630ISC6-LM12#TRMPBF is a single 12-bit voltage-output digital-to-analog converter (DAC) housed in a 6-lead SC70 package. It integrates a high-accuracy reference with a temperature coefficient of 10ppm/°C, providing a full-scale output of 2.5V. The device operates from a single 2.7V to 5.5V supply and features a rail-to-rail output buffer. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. The part includes power-on reset options for zero or mid-scale initialization and guarantees monotonicity over the operating temperature range.

Feature Summary

• Rail-to-rail output buffer capable of sourcing/sinking current
• 3-wire SPI/MICROWIRE serial interface supporting up to 50MHz clock

Applications

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

Procurement Notes

Verify the ordering suffix #TRMPBF indicates a 500-piece tape and reel packaging quantity as specified in the manufacturer's documentation. Confirm the 'I' grade corresponds to the industrial temperature range of –40°C to 85°C. Ensure the 'M' suffix denotes the power-on reset configuration set to mid-scale upon initialization.

Selection Notes

Select this specific variant for applications requiring a 2.5V full-scale output with mid-scale power-on reset behavior. The 'I' grade ensures functionality within the industrial temperature range. For higher accuracy requirements, consider the 'A' grade which offers ±1 LSB maximum INL, whereas standard grades may exhibit wider linearity errors. Verify supply voltage constraints against the 2.7V minimum requirement for the 'L' series parts.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares a common 6-lead SC70 package and core architecture but varies by full-scale voltage ('L' for 2.5V, 'H' for 4.096V), power-on reset state ('M' for mid-scale, 'Z' for zero), and accuracy grade ('A' for enhanced linearity). The ISC6 designation identifies the specific package type and temperature grade combination.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2630IZC6-LM12#TRMPBF (Zero reset) or LTC2630ACSC6-LM12#TRMPBF (Enhanced accuracy). Cross-family replacements require verification of pinout compatibility and electrical parameter alignment, particularly regarding supply voltage ranges and serial interface timing.
