LTC2632CTS8-LI8#TRPBF

Overview

The LTC2632CTS8-LI8#TRPBF is a dual 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 2.5V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 2.7V to 5.5V. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface for communication, supporting clock rates up to 50MHz. The part includes rail-to-rail output buffers and guarantees monotonicity across its operating range. Power-on reset functionality defaults to mid-scale in internal reference mode.

Feature Summary

• Dual 8-bit DACs with integrated 2.5V full-scale reference
• Low drift reference: 10ppm/°C temperature coefficient
• Single supply operation: 2.7V to 5.5V
• 3-wire SPI/MICROWIRE interface with 50MHz clock rate

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging containing 2,500 pieces. Confirm the 'C' grade corresponds to the commercial temperature range of 0°C to 70°C. Ensure the 'LI' code specifies mid-scale power-on reset behavior in internal reference mode. Check availability status as distribution channels may vary by region.

Selection Notes

Select this part when a dual-channel, low-resolution DAC is required with high accuracy and low power consumption. The 8-bit resolution offers ±0.5LSB maximum INL error. Choose this model over the 'H' variants if the system supply voltage is below 4.5V, as the 'H' series requires 4.5V to 5.5V. Consider the 'Z' or 'X' reset codes if zero-scale or external reference reset behaviors are preferred over the default mid-scale startup.

Part Context

This component belongs to the LTC2632 family, which includes 12-bit, 10-bit, and 8-bit resolutions. The 'A' electrical grade variant offers tighter linearity specifications (±1.5LSB INL), whereas the standard grade specified here has ±0.5LSB INL for the 8-bit version. The TSOT-23 package provides a compact footprint suitable for space-constrained designs.
