LTC2630HSC6-LZ12#TRMPBF

Overview

The LTC2630HSC6-LZ12#TRMPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a full-scale output of 4.096V and operates within a supply voltage range of 4.5V to 5.5V. The device utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical characteristics include a maximum integral nonlinearity (INL) of ±2 LSB, a settling time of 4.8µs at 5V, and a typical supply current of 200µA. It incorporates a power-on reset circuit that defaults the output to zero scale.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C temperature coefficient
• Rail-to-rail output buffer with guaranteed monotonicity over temperature
• Power-on reset to zero scale for consistent system initialization
• Low power operation: 200µA typical supply current; 5µA maximum in power-down mode

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF confirms the 500-unit tape and reel packaging quantity. Ensure the H-grade designation matches the required automotive temperature range of –40°C to 125°C. Confirm the LZ suffix indicates the zero-scale power-on reset configuration. Cross-reference the SC70-6 package type with PCB footprint requirements.

Selection Notes

Select this part when a 4.096V full-scale output is required with a minimum supply voltage of 4.5V. The H-grade variant is necessary for applications operating between –40°C and 125°C. Choose the LZ suffix if the system requires the DAC output to initialize to zero volts upon power-up. Verify that the 50MHz serial interface speed is compatible with the host microcontroller.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family offers combinations of full-scale voltages (2.5V or 4.096V), power-on reset options (zero or mid-scale), and temperature grades (Commercial, Industrial, Automotive). All variants share the same 6-lead SC70 package and serial interface architecture.
