LTC2630CSC6-HM8#TRPBF

Overview

The LTC2630CSC6-HM8#TRPBF is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. 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 rail-to-rail output buffer and accepts data via a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) of ±0.5 LSB, a settling time of 3.7µs at 5V, and a typical supply current of 200µA in internal reference mode. It is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C temperature coefficient
• Rail-to-rail output amplifier capable of sourcing/sinking up to 10mA
• 3-wire SPI/MICROWIRE serial interface supporting clock frequencies up to 50MHz
• Power-on reset option configured for mid-scale output initialization

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel packaging format containing 2,500 pieces. Confirm that the HM designation corresponds to the 4.096V full-scale voltage requirement and that the CSC6 package matches the SC70-6 footprint constraints. Ensure the C-grade commercial temperature rating aligns with the operational environment limits.

Selection Notes

Select this component when a low-pin-count DAC with an integrated high-accuracy reference is required for space-constrained designs. The 8-bit resolution is suitable for applications where cost and power efficiency are prioritized over high precision. Verify that the system supply voltage remains between 4.5V and 5.5V to ensure proper operation of the internal 4.096V reference circuitry.

Part Context

This part belongs to the LTC2630 family, which offers various combinations of resolution (8-, 10-, or 12-bit), full-scale voltage (2.5V or 4.096V), and power-on reset behaviors. The 'HM' suffix specifically denotes the 4.096V full-scale variant with mid-scale power-on reset, while 'C' indicates the commercial temperature grade.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2630CSC6-HZ8#TRPBF (zero-scale reset) or LTC2630CSC6-LM8#TRPBF (2.5V full-scale). Cross-family alternatives require verification of interface compatibility and reference architecture.
