Overview
The LTC6752IMS8-2#PBF is a high-speed analog comparator from Analog Devices, housed in an 8-lead MSOP package. It features rail-to-rail inputs and CMOS outputs with separate input (VCC) and output (VDD) supply pins. The device supports a VCC range of 2.45V to 5.25V and a VDD range of 1.71V to 3.5V. Key electrical characteristics include a propagation delay of 2.9ns typical, a toggle rate up to 280MHz, and an output current capability of ±22mA. It includes a shutdown pin for power reduction and operates within a temperature range of -40°C to 85°C.
Feature Summary
- Features rail-to-rail inputs that extend beyond both supply rails for flexible signal interfacing.
- Provides CMOS outputs capable of directly driving 1.8V logic devices via separate output supply options.
- Includes a dedicated shutdown pin to significantly reduce power consumption when the device is not in use.
Applications
- Clock and data recovery circuits
- High-speed line receivers
- Time of flight measurements
Procurement Notes
Verify the specific suffix #PBF indicates lead-free finish and tube packaging. Confirm the IMS8 designation corresponds to the 8-lead MSOP package. Ensure the -2 variant matches requirements for separate input/output supplies and shutdown functionality. Check manufacturer documentation for RoHS compliance details and recommended soldering profiles.
Selection Notes
Select this component when separate input and output supply voltages are required to interface with different logic levels. The -2 variant is appropriate for designs needing a shutdown control feature. Consider the MSOP package size if board space is limited. Verify that the 2.9ns propagation delay meets the timing constraints of the target application.
Part Context
This part belongs to the LTC6752 family of very high-speed comparators. The family offers various configurations including single supply, latch/hysteresis options, and complementary outputs. The IMS8-2 specifically provides the 8-lead MSOP form factor with distinct VCC and VDD pins and a shutdown control, distinguishing it from simpler variants like the TSOT-23 or SC-70 packages.
Replacement Considerations
The datasheet identifies the ADCMP60X family as a direct replacement option. Verify pin compatibility and electrical specifications before substitution.
