LTC2636CDE-LMI12#PBF

Overview

The LTC2636CDE-LMI12#PBF is an octal 12-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, providing a full-scale output of 2.5V. The device operates on a single 2.7V 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 mid-scale, and rail-to-rail output buffers guaranteed monotonic over the commercial temperature range of 0°C to 70°C.

Feature Summary

Octal 12-bit resolution with ±2.5LSB maximum integral nonlinearity error
Integrated 10ppm/°C reference yielding 2.5V full-scale output
SPI/MICROWIRE compatible 3-wire serial interface operating at 50MHz
Power-on reset to mid-scale in internal reference mode

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 and tube packaging for the DE package variant. Confirm the C grade designation aligns with the required 0°C to 70°C operating temperature range for the target application environment.

Selection Notes

Select this part when eight independent 12-bit channels are required within a compact footprint. The LMI12 suffix specifies the mid-scale power-on reset behavior and 2.5V internal reference span. Ensure the system supply voltage remains between 2.7V and 5.5V to maintain specified performance parameters.

Part Context

This component belongs to the LTC2636 family of octal DACs available in 14-lead DFN and 16-lead MSOP packages. Variants differ by resolution (8, 10, or 12 bits), power-on reset state (zero or mid-scale), and reference type (internal or external). The DE package denotes the 14-lead plastic DFN form factor.
