LTC2636IDE-LMI8#PBF

Overview

The LTC2636IDE-LMI8#PBF is an octal, 8-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 3-wire SPI/MICROWIRE-compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±0.5 LSB, a settling time of 3.4µs at 3V, and a supply current of 0.9mA. It is housed in a 14-lead DFN package and guarantees monotonicity over the industrial temperature range of –40°C to 85°C.

Feature Summary

• Octal architecture with 8 independent 8-bit DAC channels
• Integrated 2.5V full-scale reference with 10ppm/°C drift
• Rail-to-rail output buffers guaranteed monotonic over –40°C to 85°C
• SPI/MICROWIRE compatible 3-wire serial interface operating up to 50MHz

Applications

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

Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free design compliance. Confirm the DE package designation corresponds to the 14-lead DFN form factor. Ensure the LMI8 suffix matches the required 2.5V internal reference mode and mid-scale power-on reset behavior for the target application environment.

Selection Notes

Select this part for applications requiring multiple low-channel-count DACs in a compact footprint. The 8-bit resolution provides ±0.5 LSB INL accuracy suitable for general-purpose analog control. Consider the 14-lead DFN package for space-constrained designs where thermal dissipation remains within limits for the specified load currents.

Part Context

This component belongs to the LTC2636 family, which offers variations in resolution (8-, 10-, and 12-bit), package type (DFN or MSOP), and power-on reset configurations. The IDE-LMI8 variant specifically denotes the Industrial temperature grade, DFN package, Internal Reference mode, Mid-Scale reset, and 8-bit resolution.
