LTC2630ISC6-LZ10#TRMPBF

Overview

The LTC2630ISC6-LZ10#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 within a supply voltage range of 2.7V to 5.5V. The device utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a settling time of 3.9µs at 3V, and a typical supply current of 180µA. It incorporates a power-on reset circuit that defaults to zero-scale output.

Feature Summary

• Integrated 2.5V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer with guaranteed monotonicity
• Power-on reset to zero-scale for consistent initialization
• Low power operation: 180µA typical supply current

Applications

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

Procurement Notes

Verify the specific suffix #TRMPBF indicates a 500-piece tape and reel packaging format. Confirm the 'I' grade corresponds to the industrial temperature range of –40°C to 85°C. Ensure the 'LZ10' designation matches the required 2.5V full-scale output, zero-scale power-on reset, and 10-bit resolution configuration before procurement.

Selection Notes

Select this component when a single-channel DAC with low pin count is required. The 10-bit resolution offers a balance between cost and accuracy. Choose this part over the 'H' grade variants if the system supply voltage may drop below 4.5V, as the 'L' variant supports operation down to 2.7V. Verify that the 500-unit reel quantity aligns with production volume requirements.

Part Context

This part belongs to the LTC2630 family of rail-to-rail DACs available in 8-, 10-, and 12-bit resolutions. The SC70-6 package provides a compact footprint suitable for space-constrained designs. The 'I' temperature grade distinguishes it from commercial ('C') and automotive/high-temperature ('H') grades, defining its operational environmental limits.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2630ISC6-LM10#TRMPBF (mid-scale reset) or LTC2630ISC6-HZ10#TRMPBF (4.096V full-scale). Note that switching between 'L' and 'H' variants requires ensuring the supply voltage meets the minimum requirement of 4.5V for the 'H' grade.
