LTC2633CTS8-HI12

Overview

The LTC2633CTS8-HI12 is a dual-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates high-accuracy, low-drift references and operates with a single supply voltage ranging from 4.5V to 5.5V. The device features rail-to-rail output buffers 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 full scale, and a typical supply current of 0.5mA at 5V. The unit is housed in an 8-lead TSOT-23 package.

Feature Summary

Dual 12-bit DAC channels with integrated precision reference
Full-scale output of 4.096V with ±10ppm/°C temperature coefficient
Rail-to-rail output buffers guaranteed monotonic over –40°C to 125°C
Power-on reset configured 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 ordering suffix against official documentation to confirm package type, temperature grade, and power-on reset behavior. Confirm that the required supply voltage range aligns with the 4.5V to 5.5V specification for the H-grade variant. Ensure I²C bus pull-up resistors are correctly sized for the desired clock frequency.

Selection Notes

Select this component when dual isolated analog outputs are required within a compact footprint. The HI12 designation indicates a 4.096V full-scale range and mid-scale power-on reset. For lower voltage applications requiring 2.7V operation, consider the L-grade variants. Verify that the 400kHz I²C speed meets system timing requirements.

Part Context

This part belongs to the LTC2633 family of dual DACs, which also includes 10-bit and 8-bit resolutions. The family shares the same 8-lead TSOT-23 package and I²C interface architecture. Variations exist based on resolution, full-scale voltage options (2.5V or 4.096V), and power-on reset states.
