LTC2636IMS-HZ8#TRPBF

Overview

The LTC2636IMS-HZ8#TRPBF is an octal, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated high-accuracy reference with a temperature coefficient of 10ppm/°C and a full-scale output of 4.096V. The device operates on a single 4.5V to 5.5V supply and utilizes a 3-wire SPI/MICROWIRE-compatible serial interface with clock rates up to 50MHz. It includes double-buffered data latches, power-on reset to zero-scale, and rail-to-rail output buffers guaranteed monotonic over the industrial temperature range of –40°C to 85°C.

Feature Summary

• Octal 8-Bit Resolution: Provides eight independent DAC channels with 8-bit resolution.
• Integrated Reference: Features a 4.096V full-scale internal reference with ±10ppm/°C drift.
• Industrial Temperature Range: Operates reliably from –40°C to +85°C.
• Power-On Reset: Resets outputs to zero-scale upon power-up for consistent initialization.

Applications

• Process Control and Industrial Automation
• Portable Equipment
• Automotive Systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging containing 2500 pieces. Confirm the IMS designation corresponds to the 16-lead MSOP package and H-grade performance specifications. Ensure compatibility with the required 4.5V to 5.5V supply voltage range for the H-series variant.

Selection Notes

Select this part for applications requiring multiple low-cost, low-power DAC channels with moderate precision. The H-grade variant necessitates a minimum 4.5V supply, distinguishing it from the L-grade which supports 2.7V. Consider the 16-lead MSOP package if exposed pad soldering to ground is feasible for thermal management.

Part Context

This component belongs to the LTC2636 family of octal DACs. Variants differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), and power-on reset behavior (zero-scale or mid-scale). The IMS-HZ8 specifically denotes the 8-bit, 4.096V, zero-reset version in the MSOP package.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2636IMS-LZ8#TRPBF (2.5V FS, lower supply) or LTC2636IMS-HZ12#TRPBF (12-bit resolution). Verify that the alternative's full-scale voltage and supply requirements match the system design constraints.
