LTC2630CSC6-HM10#TRMPBF

Overview

The LTC2630CSC6-HM10#TRMPBF is a single-channel, 10-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 supports SPI/MICROWIRE compatible 3-wire serial interfaces with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of 1 LSB, a settling time of 4.4µs at ±1 LSB for 10-bit resolution, and a typical supply current of 200µA. The component is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated precision reference with 10ppm/°C drift for 4.096V full-scale output
• SPI/MICROWIRE compatible 3-wire serial interface supporting up to 50MHz clock rates
• Power-on reset options configurable to zero or mid-scale via command codes
• Low power consumption with 200µA typical supply current and 1.8µA maximum power-down current

Applications

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

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 HM designation corresponds to the 4.096V full-scale voltage and mid-scale power-on reset behavior. Ensure the C temperature grade aligns with the required operational range of 0°C to 70°C for the target application environment.

Selection Notes

Select this model when a 4.096V internal reference is required alongside a 10-bit resolution. The H-grade internal reference necessitates a minimum supply voltage of 4.5V, distinguishing it from L-grade variants that operate down to 2.7V. Consider the mid-scale power-on reset feature if downstream circuitry requires a non-zero initial state upon system startup. Verify that the 6-lead SC70 package dimensions fit the available PCB real estate constraints.

Part Context

This component belongs to the LTC2630 family of single-channel DACs, which offers combinations of 8-, 10-, and 12-bit resolutions with varying full-scale voltages. The 'HM' suffix specifically denotes the 10-bit resolution variant with a 4.096V internal reference and mid-scale power-on reset. The 'C' suffix identifies the commercial temperature grade, while 'SC6' confirms the 6-lead SC70 plastic package type used for space-constrained designs.

Replacement Considerations

Direct functional substitutes within the same family include the LTC2630CSC6-HZ10#TRMPBF, which shares identical electrical characteristics but resets to zero scale upon power-up instead of mid-scale. Other resolution variants such as the LTC2630CSC6-HM12#TRMPBF (12-bit) or LTC2630CSC6-HM8#TRMPBF (8-bit) may be considered if resolution requirements differ, provided the pinout and interface remain compatible.
