LTC2630ISC6-LZ10#TRPBF

Overview

The LTC2630ISC6-LZ10#TRPBF is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference and operates in a 6-lead SC70 package. This specific variant features an internal reference with a full-scale output of 2.5V and is designed for the industrial temperature range (-40°C to +85°C). 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 ±1 LSB, a settling time of 3.9µs at 3V supply, and a typical supply current of 180µA.

Feature Summary

• 10-bit resolution with guaranteed monotonicity over temperature
• Integrated precision reference providing 2.5V full-scale output
• Power-on reset to zero-scale code upon initialization
• Industrial temperature grade (-40°C to +85°C)
• Low power consumption: 180µA typical at 3V; 1.8µA max in power-down mode

Applications

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

Procurement Notes

Verify the ordering suffix #TRPBF indicates a tape and reel packaging format containing 2,500 pieces. Confirm the 'I' designation corresponds to the industrial temperature range (-40°C to +85°C) and the 'Z' suffix ensures a zero-scale power-on reset state. Ensure the 'L' designation matches the required 2.5V full-scale output specification for the application.

Selection Notes

Select this part when a 10-bit resolution is sufficient and a compact 6-lead SC70 package is required. Choose the LZ configuration if a zero-volt output state is mandatory immediately after power-up. The I-grade is necessary for environments operating between -40°C and +85°C. For applications requiring a 4.096V full-scale output, the H-grade variant must be selected instead.

Part Context

This component belongs to the LTC2630 family of rail-to-rail DACs. The family offers combinations of 8-, 10-, and 12-bit resolutions with either 2.5V or 4.096V internal references. The ISC6-LZ10 variant specifically combines the industrial temperature grade, the 10-bit resolution, and the zero-reset feature within the small SC70 footprint.

Replacement Considerations

Direct replacements within the same package and pinout include other LTC2630 variants such as the LTC2630ISC6-HZ10#TRPBF (4.096V FS) or LTC2630ISC6-LM10#TRPBF (mid-scale reset). Cross-family replacements require verification of pin compatibility and electrical specifications.
