LTC2630ACSC6-HZ12#TRPBF

Overview

The LTC2630ACSC6-HZ12#TRPBF 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 characteristics include a maximum integral nonlinearity (INL) error of ±1 LSB, a settling time of 4.8µs at 5V, and a typical supply current of 200µA. It incorporates a power-on reset circuit that defaults the output to zero scale.

Feature Summary

• 12-bit resolution with ±1 LSB maximum INL error
• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer guaranteed monotonic over temperature
• Power-on reset to zero scale for consistent system initialization

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel quantity, distinct from the standard 2500-unit #TRPBF configuration. Confirm the H-grade designation corresponds to the automotive temperature range of –40°C to +125°C. Ensure the Z-suffix is selected if zero-scale power-on reset behavior is required for the design.

Selection Notes

Select this part when a compact SC70 package is required alongside high DC accuracy defined by the A-grade ±1 LSB INL specification. The H-grade variant is necessary for environments requiring operation up to 125°C junction temperature. Verify that the 4.5V minimum supply voltage aligns with the system's power rails, as the L-grade variant supports lower voltages down to 2.7V.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares a common 6-lead SC70 footprint and SPI interface architecture. Variations exist based on full-scale voltage (2.5V or 4.096V), power-on reset state (zero or mid-scale), and temperature grade (Commercial, Industrial, or Automotive).
