LTC2637IMS-LMI10#PBF

Overview

The LTC2637IMS-LMI10#PBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a 10ppm/°C temperature coefficient, providing a full-scale output of 2.5V. The device operates on a single 2.7V 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 ±1 LSB, a settling time of 4.1µs, and double-buffered data latches. The component is housed in a 16-lead MSOP package and guarantees monotonicity over the industrial temperature range of –40°C to 85°C.

Feature Summary

• Octal architecture with 10-bit resolution and rail-to-rail output buffers
• Integrated 2.5V precision reference with 10ppm/°C drift
• Ultralow DAC-to-DAC crosstalk (<3nV•s)
• Double-buffered data latches for synchronized updates

Applications

• Process control and industrial automation systems
• Portable equipment requiring low power consumption
• Automatic test equipment
• Mobile communications infrastructure

Procurement Notes

Verify the specific ordering suffix LMI10#PBF against the manufacturer's current documentation to confirm lead-free status and tape-and-reel packaging details. Ensure the procurement channel provides valid traceability for the Analog Devices brand. Cross-reference the part number with official distributors to confirm availability in the 16-lead MSOP package format.

Selection Notes

Select this part when eight independent 10-bit voltage outputs are required within a compact footprint. The internal 2.5V reference suits applications where a 2.7V to 5.5V supply is available. Compare INL performance against other resolutions if higher accuracy is needed, or consider the LTC2637-H variant for 4.096V full-scale outputs requiring a 4.5V minimum supply.

Part Context

This component belongs to the LTC2637 family of octal DACs, which also includes 12-bit and 8-bit variants. The 'I' designation indicates the industrial temperature grade (–40°C to 85°C), while 'MS' specifies the 16-lead MSOP package. The 'LMI10' suffix defines the 2.5V internal reference, mid-scale power-on reset behavior, and 10-bit resolution.

Replacement Considerations

Direct pin-compatible substitutes within the same family include LTC2637IMS-LZ10#PBF (zero-scale reset) and LTC2637IMS-LMX10#PBF (external reference mode). For different resolutions, LTC2637IMS-LMI12#PBF (12-bit) and LTC2637IMS-LMI8#PBF (8-bit) share the same package and interface.
