LTC2637HMS-HZ8#TRPBF

Overview

The LTC2637HMS-HZ8#TRPBF is an octal 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a 10ppm/°C drift rate, providing a full-scale output of 4.096V. The device operates on a single 4.5V to 5.5V supply and utilizes 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 ±0.5 LSB, a settling time of 3.9µs, and double-buffered data latches for glitch-free updates.

Feature Summary

Octal architecture with 8 independent DAC channels in a 16-lead MSOP package
Integrated 4.096V full-scale reference with 10ppm/°C temperature coefficient
Rail-to-rail output buffers guaranteed monotonic over –40°C to 125°C
Ultralow DAC-to-DAC crosstalk (<3nV•s) and double-buffered data latches

Applications

Mobile communications systems
Process control and industrial automation
Automatic test equipment
Portable battery-powered equipment
Automotive electronics
Optical networking devices

Procurement Notes

Verify the H-grade automotive temperature rating (-40°C to 125°C) and the specific power-on reset configuration (Zero-Scale). Confirm the MSOP-16 package type matches the design footprint. Ensure the I2C address pins (CA0, CA1, CA2) are correctly terminated to avoid bus conflicts in multi-device setups.

Selection Notes

Select this part when eight low-channel-count DACs are required in a compact surface-mount form factor. The H-grade variant is necessary for high-temperature automotive or industrial environments. Compare against the L-grade if a lower 2.7V supply voltage and 2.5V full-scale range are acceptable for the application.

Part Context

This component belongs to the LTC2637 family, which includes 12-bit, 10-bit, and 8-bit resolutions. The 'H' suffix denotes the automotive temperature grade, while 'MS' indicates the 16-lead MSOP package. The 'Z8' specifies the 8-bit resolution with a Zero-Scale power-on reset behavior.
