LTC2636HDE-HZ12#TRPBF

Digital To Analog Converters Overview

The LTC2636HDE-HZ12#TRPBF is an octal 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc. It features an integrated high-accuracy reference with a temperature coefficient of 10ppm/°C, providing a full-scale output of 4.096V. The device operates on a single supply voltage ranging from 4.5V to 5.5V and includes rail-to-rail output buffers that are guaranteed monotonic over the –40°C to 125°C automotive temperature range. Communication is handled via a 3-wire SPI/MICROWIRE-compatible interface supporting clock rates up to 50MHz. The part incorporates a power-on reset circuit configured to clear outputs to zero-scale upon initialization.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel quantity of 2500 pieces. Confirm the DE package designation corresponds to the 14-lead DFN form factor. Ensure the H-grade specification matches the required 4.5V to 5.5V supply range and automotive temperature capabilities for the target application environment.

Digital To Analog Converters Selection Notes

Select this component when eight independent 12-bit channels are required with high precision and automotive reliability. The internal 4.096V reference eliminates the need for external components if this voltage level is suitable. Compare against LTC2636-L variants if a lower 2.7V–5.5V supply range or 2.5V full-scale output is needed instead.

Digital To Analog Converters Part Context

This part belongs to the LTC2636 family of octal DACs, which offers variations in 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 H suffix denotes the 4.096V internal reference version, while Z indicates the zero-scale reset configuration. The DE suffix specifies the 14-lead DFN package.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include other LTC2636 variants differing only in resolution, reset mode, or package type. For example, LTC2636HDE-MX12#TRPBF provides mid-scale reset in external reference mode. Cross-family replacements require verification of pin compatibility and electrical specifications.
