LTC2630CSC6-LM10#TRPBF

Overview

The LTC2630CSC6-LM10#TRPBF 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 on a single supply ranging from 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) of ±1 LSB, a settling time of 3.9µs at 3V, and a typical supply current of 180µA. It incorporates double-buffered data latches and power-on reset options.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel packaging format containing 2,500 pieces. Confirm that the LM10 designation corresponds to the 10-bit resolution with mid-scale power-on reset and 2.5V full-scale output as defined in the manufacturer's selection guide. Ensure compatibility with the commercial temperature grade (0°C to 70°C) specified by the C suffix.

Selection Notes

Select this component when a single-channel DAC with 10-bit resolution and an integrated 2.5V reference is required in a compact SC-70 package. Choose the LM variant if a mid-scale output state is desired upon power-up rather than zero-scale. Verify that the system supply voltage falls within the 2.7V to 5.5V range for the L-grade devices. Consider the H-grade variants only if a 4.096V full-scale output and a higher minimum supply voltage of 4.5V are acceptable.

Part Context

This part belongs to the LTC2630 family of rail-to-rail DACs available in 8-, 10-, and 12-bit resolutions. The family distinguishes between L-grade parts operating from 2.7V–5.5V with a 2.5V internal reference and H-grade parts requiring 4.5V–5.5V with a 4.096V internal reference. The SC-70 package allows for space-constrained designs while maintaining low power consumption suitable for portable applications.
