LTC2630ISC6-HZ12#TRPBF

Overview

The LTC2630ISC6-HZ12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) housed in a 6-lead SC70 package. 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) error of ±2 LSB, a settling time of 4.8µs at 5V, and a typical supply current of 200µA. The part supports power-down modes reducing current to 1.8µA and includes a power-on reset function that clears the output to zero scale.

Feature Summary

• Integrated 4.096V 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 systems
• Process control and industrial automation
• Automatic test equipment
• Portable battery-powered equipment
• Automotive electronics

Procurement Notes

Verify the specific suffix #TRPBF indicates a 2,500-piece tape and reel packaging format. Confirm the 'I' grade designation corresponds to the industrial temperature range of –40°C to 85°C. Ensure the ordering information matches the required resolution and reset configuration before procurement.

Selection Notes

Select this component when a compact 12-bit DAC with an integrated high-accuracy reference is required in space-constrained designs. Choose the H-grade variant for applications requiring a 4.096V full-scale output and operation above 4.5V. The I-grade temperature rating is suitable for industrial environments. Consider the Z-suffix for power-on reset to zero if downstream circuitry requires a known low state during startup.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares a common 6-lead SC70 footprint and core architecture but varies by temperature grade (C, I, H), full-scale voltage (L: 2.5V, H: 4.096V), and power-on reset behavior (M: mid-scale, Z: zero). The ISC6-HZ12 designation specifies the Industrial grade, SC70 package, High full-scale voltage, and Zero reset configuration.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2630ISC6-LZ12#TRPBF (2.5V full-scale) or LTC2630HSC6-HZ12#TRPBF (Automotive grade). Verify that the alternative part's temperature range and full-scale voltage meet the specific application requirements.
