LTC2633AHTS8-HI12#TRPBF

Overview

The LTC2633AHTS8-HI12#TRPBF is a dual 12-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 4.5V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 125°C temperature range, and 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 ±1.5 LSB, a settling time of 4.7µs at 5V, and a supply current of 0.5mA at 5V.

Feature Summary

• Dual 12-bit DACs with integrated 4.096V precision reference (±10ppm/°C drift)
• Maximum INL error of ±1.5 LSB for high accuracy
• Rail-to-rail output buffers with 4.7µs settling time
• Power-on reset configurable to mid-scale in internal reference mode

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Power Supply Margining
• Portable Equipment
• Automotive Systems

Procurement Notes

Verify the specific suffix #TRPBF indicates a tape and reel packaging format containing 2,500 pieces. Confirm that the HI designation requires a supply voltage between 4.5V and 5.5V, as this differs from the L-grade variants which operate down to 2.7V. Ensure the A-grade specification for ±1.5 LSB INL is required for the application's precision needs.

Selection Notes

Select this part when dual-channel 12-bit resolution is required within an 8-lead TSOT-23 package. The HI suffix mandates a minimum 4.5V supply; if lower voltage operation (2.7V–5.5V) is needed, consider the LTC2633-L series. The A-grade offers tighter linearity (±1.5 LSB) compared to the standard grade (±2.5 LSB). Verify I²C address configuration via the CA0 pin if multiple devices are used on the same bus.

Part Context

This component belongs to the LTC2633 family of dual DACs. The 'A' denotes the electrical grade with improved linearity, 'H' specifies the 4.096V full-scale internal reference requiring 4.5V+ supply, 'I' sets the power-on reset to mid-scale, and '12' indicates 12-bit resolution. The TS8 package is an 8-lead ThinSOT (TSOT-23).
