LTC2630HSC6-HM8#TRPBF

Overview

The LTC2630HSC6-HM8#TRPBF is an 8-bit, single-channel voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a rail-to-rail output buffer and an integrated precision reference with a full-scale output of 4.096V. The device operates on a single supply voltage ranging from 4.5V to 5.5V and 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. The part is housed in a compact 6-lead SC70 package and includes power-on reset functionality set to mid-scale.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C temperature coefficient
• Rail-to-rail output buffer guaranteed monotonic over temperature
• 3-wire SPI/MICROWIRE serial interface supporting up to 50MHz clock
• Power-on reset to mid-scale with selectable internal or supply reference modes

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates a 2,500-piece tape and reel packaging configuration. Confirm that the H-grade designation aligns with the required automotive temperature range of –40°C to +125°C for the target application environment. Ensure the 4.5V minimum supply voltage requirement is met by the system power rails.

Selection Notes

Select this component when a compact 6-lead SC70 footprint is required alongside an integrated 4.096V reference. Choose the HM variant if a mid-scale power-on reset state is necessary for system initialization safety. Consider the 8-bit resolution and ±2 LSB INL specification against application accuracy requirements before opting for higher-resolution variants like the LTC2630-12.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The 'H' suffix denotes the automotive temperature grade (-40°C to +125°C), while 'M' specifies the mid-scale power-on reset behavior. The 'SC6' indicates the 6-lead SC70 plastic package, distinguishing it from larger surface-mount options.

Replacement Considerations

Direct pin-compatible substitutes within the same family include LTC2630HSC6-HZ8#TRPBF (zero-scale reset) or LTC2630HSC6-HM10#TRPBF (10-bit resolution). Verify that any replacement maintains the 4.5V–5.5V supply range and the specific power-on reset state required by the host system logic.
