LTC2637IMS-LMI10#TRPBF

Overview

The LTC2637IMS-LMI10#TRPBF is an octal 10-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 operates on a single 2.7V to 5.5V supply. The device 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 ±1 LSB, a settling time of 4.1µs at ±1 LSB, and ultralow DAC-to-DAC crosstalk below 3nV•s. It incorporates double-buffered data latches and power-on reset options.

Feature Summary

• Octal architecture with 8 independent 10-bit channels in a 16-lead MSOP package
• Integrated 10ppm/°C precision reference providing 2.5V full-scale output
• Ultralow inter-channel crosstalk (<3nV•s) and guaranteed monotonicity over temperature
• Double-buffered data latches for synchronized multi-channel updates

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 specific suffix #TRPBF indicates tape and reel packaging containing 2500 units. Confirm the IMS designation corresponds to the 16-lead MSOP package and the LMI10 code specifies the 10-bit resolution with mid-scale power-on reset behavior. Ensure the component meets the required industrial temperature range (-40°C to +85°C).

Selection Notes

Select this part when eight isolated analog outputs are required within a compact footprint. The 10-bit resolution balances cost and performance for applications not requiring 12-bit precision. Verify that the 2.5V internal reference span fits the system signal requirements; otherwise, consider external reference configurations or different full-scale variants.

Part Context

This component belongs to the LTC2637 family, which includes 12-bit, 10-bit, and 8-bit variants. The 'I' grade denotes the industrial temperature range (-40°C to 85°C), while the 'H' grade supports automotive temperatures up to 125°C. The 'MS' package type distinguishes it from the smaller 14-lead DFN option.

Replacement Considerations

Direct functional substitutes within the same family include LTC2637IMS-LMI12#TRPBF (12-bit) and LTC2637IMS-LMI8#TRPBF (8-bit). For quad-channel requirements, the LTC2634 series offers similar specifications but with fewer channels and potentially different pinouts.
