LTC2632ACTS8-LZ12#TRPBF

Overview

The LTC2632ACTS8-LZ12#TRPBF is a dual 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated 2.5V full-scale reference with a temperature coefficient of 10ppm/°C. The device operates on a single supply ranging from 2.7V to 5.5V and utilizes a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1.5LSB, a settling time of 4.4µs at 3V, and rail-to-rail output buffers. The part is guaranteed monotonic and includes a power-on reset function that clears the output to zero-scale.

Feature Summary

• Dual 12-bit resolution with ±1.5LSB maximum INL error
• Integrated 2.5V full-scale reference with 10ppm/°C drift
• Power-on reset to zero-scale in internal reference mode
• 3-wire serial interface supporting clock rates up to 50MHz

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF versus #TRPBF against official documentation to confirm tape and reel quantity requirements. Confirm availability status through authorized distributors as stock levels fluctuate. Ensure the component meets RoHS compliance standards required for the target assembly process.

Selection Notes

Select this part when a dual-channel DAC with high accuracy (±1.5LSB INL) and low drift is required. The LZ suffix indicates a zero-scale power-on reset, suitable for systems where outputs must be inactive during initialization. Verify that the 2.7V to 5.5V supply range aligns with the system power architecture.

Part Context

This component belongs to the LTC2632 family, which offers various combinations of resolution (8-, 10-, or 12-bit), full-scale voltage (2.5V or 4.096V), and power-on reset behaviors. The ACTS8 designation specifies the automotive-grade temperature range and the 8-lead TSOT-23 package type.

Replacement Considerations

Direct substitutes within the same family include LTC2632ACTS8-LI12#TRPBF (mid-scale reset) and LTC2632ACTS8-HZ12#TRPBF (4.096V full-scale). Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
