LTC2633HTS8-LO10#TRPBF

Overview

The LTC2633HTS8-LO10#TRPBF is a dual-channel, 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 4.096V and operates on a single supply voltage ranging from 4.5V to 5.5V. The device communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a settling time of 4.0µs at ±1LSB for 10-bit resolution, and a supply current of 0.5mA at 5V. The unit is housed in an 8-lead TSOT-23 package and guarantees monotonic operation over the –40°C to 125°C temperature range.

Feature Summary

• Dual 10-bit DAC channels with rail-to-rail output buffers
• Integrated 4.096V precision reference with 10ppm/°C drift
• Power-on reset to high-impedance state for safe initialization
• I²C interface with selectable slave address via CA0 pin

Applications

• Mobile communications systems
• Process control and industrial automation
• Portable equipment requiring low power consumption

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel quantity of 2,500 pieces. Confirm the HTS8 designation corresponds to the Automotive temperature grade (-40°C to 125°C) and TSOT-23 package. Ensure compatibility with the required 4.5V to 5.5V supply voltage range before procurement.

Selection Notes

Select this part when a dual-channel DAC with a fixed 4.096V internal reference is required. The LO10 suffix specifies a 10-bit resolution with a power-on reset to high impedance. Compare against the HI10 variant if mid-scale reset is preferred over high impedance, or the LZ10 variant if zero-scale reset is necessary for system safety.

Part Context

This component belongs to the LTC2633 family of dual DACs. Variants are distinguished by resolution (8, 10, or 12 bits), full-scale voltage (2.5V for L-grade, 4.096V for H-grade), and power-on reset behavior (I, X, O, Z). The HTS8-LO10 specifically combines the H-grade voltage, 10-bit resolution, and high-impedance reset option.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pinout and register compatibility if considering alternative dual-channel I²C DACs from other manufacturers.
