LTC2632ACTS8-HI12#TRMPBF

Digital To Analog Converters Overview

The LTC2632ACTS8-HI12#TRMPBF is a dual 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in an 8-lead TSOT-23 package. It features an integrated precision reference with a full-scale output of 4.096V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 4.5V to 5.5V. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1.5LSB, a settling time of 4.9µs at 5V, and rail-to-rail output buffers. The part includes a power-on reset circuit configured to set outputs to mid-scale upon initialization.

Digital To Analog Converters Feature Summary

• Dual 12-bit DACs with integrated 4.096V reference (±10ppm/°C)
• Maximum INL error of ±1.5LSB for high accuracy
• SPI/MICROWIRE compatible 3-wire serial interface (up to 50MHz)
• Power-on reset to mid-scale in internal reference mode

Digital To Analog Converters Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive Systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel packaging configuration. Confirm that the HI designation requires a supply voltage range of 4.5V to 5.5V, distinct from the LI variant which supports lower voltages. Ensure the A grade specification for ±1.5LSB INL matches the design requirements.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel DAC with a fixed 4.096V internal reference is required. The HI suffix dictates a minimum operating voltage of 4.5V. For applications requiring zero-scale power-on reset, consider the HZ suffix instead. Verify that the 8-lead TSOT-23 package footprint fits the PCB layout constraints.

Digital To Analog Converters Part Context

This part belongs to the LTC2632 family of dual DACs. Variations exist based on resolution (8, 10, or 12-bit), full-scale voltage (2.5V or 4.096V), and power-on reset behavior (Zero, Mid-Scale Internal, or Mid-Scale External). The ACTS8 designation specifies the Automotive-grade temperature range (-40°C to 125°C) and the TSOT-23 package type.
