LTC2630CSC6-LZ10

Overview

The LTC2630CSC6-LZ10 is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision 2.5V reference with a 10ppm/°C temperature coefficient and operates on a single 2.7V to 5.5V supply. The device features a rail-to-rail output buffer, guaranteed monotonicity, and low power consumption of 190µA at 3V. It utilizes a 3-wire SPI/MICROWIRE interface with clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 3.9µs, and a power-on reset to zero-scale. The component is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated Precision Reference: Provides a stable 2.5V full-scale output with a low drift of 10ppm/°C.
• High Accuracy: Guarantees monotonic operation over the operating temperature range with a maximum INL error of ±1 LSB.
• Low Power Consumption: Draws only 190µA during normal operation and reduces to 1.8µA maximum in power-down mode.
• Compact Packaging: Available in a tiny 6-lead SC70 package to maximize board density.

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel quantity of 2,500 pieces. Confirm the temperature grade 'C' corresponds to the commercial range of 0°C to 70°C. Ensure the 'LZ' designation matches the requirement for a 2.5V internal reference and zero-scale power-on reset. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm lead-free compliance and RoHS status.

Selection Notes

Select this model when a single-channel 10-bit resolution is sufficient for the application. Choose the 'L' suffix variant if the system requires a 2.5V full-scale output and operates within a 2.7V to 5.5V supply range. Opt for the 'Z' power-on reset configuration if the downstream circuitry requires the DAC output to initialize at zero volts upon power-up. Verify that the SC70 package dimensions fit the available PCB space constraints.

Part Context

This component belongs to the LTC2630 family of single-channel DACs. The family includes variants with 12-bit, 10-bit, and 8-bit resolutions. Other suffixes indicate different full-scale voltages (4.096V for 'H' grade) or mid-scale power-on resets ('M'). All members share the same 6-lead SC70 package and SPI-compatible serial interface architecture.
