LTC2630ACSC6-HZ12#TRMPBF

Overview

The LTC2630ACSC6-HZ12#TRMPBF is a single-channel, 12-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 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a typical supply current of 200µA at 5V, and a power-down mode consuming 1.8µA maximum. The part incorporates a power-on reset circuit configured to clear the output to zero scale upon initialization.

Feature Summary

• 12-bit resolution with ±1 LSB maximum INL error
• Integrated 4.096V precision reference with 10ppm/°C drift
• Power-on reset to zero scale for consistent system initialization
• Low power consumption: 200µA active, 1.8µA in power-down

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration. Confirm that the 'H' temperature grade designation aligns with the required operating range of –40°C to +125°C for the target application environment. Ensure the 'Z' power-on reset setting matches system startup requirements.

Selection Notes

Select this component when a compact 6-lead SC70 package is required alongside high accuracy (±1 LSB INL). Choose the H-grade variant if operation beyond the commercial temperature range is necessary. Verify that the 4.5V minimum supply voltage requirement fits the system power architecture, as lower voltage variants are available for 2.7V systems.

Part Context

This part belongs to the LTC2630 family of rail-to-rail DACs. The 'A' suffix denotes the highest accuracy grade with ±1 LSB INL. The 'HZ12' combination specifies the 4.096V internal reference, zero-scale power-on reset, and 12-bit resolution. The 'C' indicates the standard commercial package type, while 'H' defines the extended temperature performance.

Replacement Considerations

Direct replacements within the same series include LTC2630HCSC6-HZ12#TRMPBF for identical electrical performance but potentially different manufacturing lot characteristics. For applications requiring mid-scale power-on reset instead of zero-scale, consider the LTC2630HCSC6-HM12#TRMPBF variant.
