LTC2644IMS-L12#PBF

Overview

The LTC2644IMS-L12#PBF is a dual-channel, 12-bit PWM-to-voltage output DAC from Analog Devices. It features an integrated 10ppm/°C reference providing a 2.5V full-scale output and operates on a single 2.7V to 5.5V supply. The device converts PWM input signals into buffered analog voltages with no latency, updating outputs within 8µs typically. It supports pin-selectable internal or external references and includes idle mode selection for power management. The component is housed in a 12-lead MSOP package and is guaranteed monotonic over the industrial temperature range of –40°C to 85°C.

Feature Summary

Dual 12-bit resolution with ±2.5LSB max INL and ±1LSB max DNL
Integrated 10ppm/°C reference yielding 2.5V full-scale output
No-latency PWM-to-voltage conversion settling within 8µs
Rail-to-rail output buffers sourcing/sinking up to 10mA at 5V

Applications

Digital Calibration
Trimming and Adjustment
Level Setting
Process Control and Industrial Automation
Instrumentation

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm the IMS designation corresponds to the industrial temperature grade (–40°C to 85°C). Ensure compatibility with the 12-lead MSOP footprint during PCB design. Check for RoHS compliance status as indicated in official documentation.

Selection Notes

Select this model for applications requiring high accuracy without digital interfaces like SPI or I2C. The 12-bit resolution is suitable for precision calibration tasks. Consider the 8µs settling time against system update rates. Verify that the PWM input frequency remains within the 30Hz to 6.25kHz limit for 12-bit operation.

Part Context

This part belongs to the LTC2644 family, which also offers 10-bit and 8-bit resolutions. Variants include the LTC2644-L10 and LTC2644-L8. Other family members include the quad-channel LTC2645. The device replaces slow analog filters and buffer amplifiers in traditional PWM-to-voltage circuits.
