LTC2630CSC6-LZ8#TRMPBF

Overview

The LTC2630CSC6-LZ8#TRMPBF is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 2.5V and operates on a single supply ranging from 2.7V to 5.5V. The device utilizes a rail-to-rail output buffer and communicates via 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 ±0.5 LSB, a settling time of 3.2µs at 3V, and a typical supply current of 180µA. The component is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated 2.5V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer guaranteed monotonic over temperature
• 3-wire SPI/MICROWIRE serial interface supporting up to 50MHz clock
• Power-on reset to zero-scale for consistent system initialization

Applications

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

Procurement Notes

Verify the #TRMPBF suffix indicates a 500-unit tape and reel packaging configuration as specified in the ordering information. Confirm the C-grade designation corresponds to the commercial operating temperature range of 0°C to 70°C. Ensure the LZ8 suffix aligns with the zero-scale power-on reset and 8-bit resolution requirements for the specific design application.

Selection Notes

Select this part when a compact 6-lead SC70 package is required for space-constrained designs. Choose the LTC2630-L variant if the application requires operation from a 2.7V supply; use the -H variant only if the supply voltage is between 4.5V and 5.5V. Opt for the -Z suffix if a zero-scale output upon power-up is necessary to prevent glitches in downstream circuits during initialization.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares identical pinouts and serial interface protocols but differs in accuracy grades (standard vs. A-grade), full-scale voltage options (2.5V or 4.096V), and power-on reset behaviors. The 8-bit version offers lower cost and reduced data throughput requirements compared to higher-resolution variants.
