LTC2630HSC6-LM8#TRMPBF

Overview

The Analog Devices LTC2630HSC6-LM8#TRMPBF is an 8-bit, single-channel 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) of ±2 LSB, a settling time of 4.8µs at 5V, and a typical supply current of 200µA. It incorporates double-buffered data latches and power-on reset functionality set to mid-scale.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C temperature coefficient
• 8-bit resolution with guaranteed monotonicity over the operating temperature range
• 3-wire serial interface supporting clock frequencies up to 50MHz
• Power-on reset configured to mid-scale output upon 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 suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration as defined in the manufacturer's ordering information. Confirm that the H-grade designation aligns with the required automotive temperature range of –40°C to +125°C for the target application environment.

Selection Notes

Select this component when a compact 6-lead SC70 footprint is required alongside an internal 4.096V reference source. Ensure the system supply voltage remains between 4.5V and 5.5V, as lower voltages will prevent proper operation of the H-grade variant. Consider the 4.8µs settling time for bandwidth requirements and verify compatibility with the 3-wire SPI protocol.

Part Context

This part belongs to the LTC2630 family, which offers combinations of 12-, 10-, and 8-bit resolutions with selectable full-scale outputs of 2.5V or 4.096V. The 'H' suffix denotes the automotive temperature grade, while 'LM' specifies the mid-scale power-on reset behavior and 4.096V full-scale voltage derived from the internal reference.
