LTC2630ISC6-LZ12#TRPBF

Overview

The LTC2630ISC6-LZ12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference and operates in a 6-lead SC70 package. The device features a rail-to-rail output buffer and supports an SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. In internal reference mode, it provides a full-scale output of 2.5V and operates from a 2.7V to 5.5V supply. Key electrical parameters 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 part includes a power-on reset circuit configured to clear the output to zero scale upon initialization.

Feature Summary

• 12-bit resolution with guaranteed monotonicity over temperature
• Integrated precision reference providing 2.5V full-scale output
• Power-on reset to zero scale for consistent system initialization
• Low power operation: 180µA typical supply current; 1.8µA max in power-down

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive systems

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's datasheet to confirm temperature grade, resolution, and power-on reset configuration. Ensure the SC70-6 package footprint matches the design requirements. Confirm RoHS compliance status through official documentation before procurement.

Selection Notes

Select this component when a compact, low-power DAC with integrated reference is required. The 'I' grade indicates an industrial temperature range of –40°C to 85°C. The 'Z' suffix specifies a power-on reset to zero scale, which is critical for applications where downstream circuits must remain inactive during startup. Compare INL specifications if higher accuracy is needed.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family offers various combinations of full-scale voltages (2.5V or 4.096V), power-on reset options (zero or mid-scale), and temperature grades (Commercial, Industrial, Automotive). All variants share the same 6-lead SC70 package and serial interface architecture.

Replacement Considerations
