LTC2630ISC6-LM12#TRPBF

Overview

The LTC2630ISC6-LM12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference and rail-to-rail output buffer within a compact 6-lead SC70 package. The device operates on a single supply ranging from 2.7V to 5.5V, delivering a full-scale output of 2.5V in internal reference mode. It features a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) of ±2 LSB, a settling time of 4.4µs at 3V, and a typical supply current of 180µA. The component supports power-down modes reducing current to 1.8µA and includes power-on reset options.

Feature Summary

• 12-bit resolution with guaranteed monotonicity over temperature
• Integrated precision reference providing 2.5V full-scale output
• Rail-to-rail output buffer capable of driving capacitive loads up to 500pF
• 3-wire serial interface supporting clock frequencies up to 50MHz

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 #TRPBF indicates a tape and reel packaging configuration containing 2,500 pieces. Confirm that the 'I' grade designation matches the required industrial operating temperature range of –40°C to 85°C for the target application environment.

Selection Notes

Select this part when a 12-bit resolution and 2.5V full-scale output are required in a minimal footprint. Ensure the system supply voltage remains between 2.7V and 5.5V. Consider the power-on reset behavior; this variant resets to mid-scale ('M'), whereas other variants may reset to zero-scale ('Z'). Verify that the 1.8µA power-down current meets low-power standby requirements.

Part Context

This component belongs to the LTC2630 family of single-channel DACs. Variants within the family differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), and power-on reset state (zero or mid-scale). The ISC6-LM12 designation specifically identifies the Industrial grade, SC70 package, Mid-scale reset, and 12-bit resolution configuration.

Replacement Considerations

Direct functional substitutes within the same family include the LTC2630ISC6-HM12#TRPBF (4.096V full scale) or the LTC2630ISC6-LZ12#TRPBF (Zero-scale reset). Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
