LTC2637IDE-HMX10#TRPBF

Overview

The LTC2637IDE-HMX10#TRPBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a temperature coefficient of 10ppm/°C, providing a full-scale output of 4.096V. The device operates on a single 4.5V to 5.5V supply and communicates via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical characteristics include a maximum integral nonlinearity (INL) error of ±1 LSB, a settling time of 4.3µs at ±1 LSB, and ultralow DAC-to-DAC crosstalk below 3nV•s. The part is housed in a 16-lead MSOP package and includes double-buffered data latches.

Feature Summary

• Octal 10-bit resolution with rail-to-rail output buffers guaranteed monotonic over the operating temperature range.
• Integrated 10ppm/°C precision reference yielding a 4.096V full-scale output.
• Ultralow crosstalk between DAC channels (<3nV•s) and low power consumption (1mA typical supply current).
• Power-on reset configured to mid-scale in external reference mode (HMX suffix).

Applications

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

Procurement Notes

Verify the specific ordering suffix HMX10#TRPBF against the manufacturer's documentation to confirm the internal reference configuration, resolution, and tape-and-reel packaging details. Ensure the design supports the required 4.5V to 5.5V supply voltage range for the H-grade variant.

Selection Notes

Select this component when an octal DAC architecture is required with high channel density in a small footprint. The HMX suffix indicates a power-on reset to mid-scale in external reference mode; choose Z or MI suffixes if zero-scale or internal reference mid-scale resets are preferred. Verify that the 4.096V internal full-scale range meets system requirements.

Part Context

This part belongs to the LTC2637 family of octal DACs available in 12-, 10-, and 8-bit resolutions. The 'I' designation specifies the industrial temperature grade (-40°C to 85°C), while 'H' denotes the 4.096V full-scale output capability. The 'MS' indicates the 16-lead MSOP package, and 'TRPBF' signifies tape-and-reel packaging with lead-free finish.
