Overview
The LMH7220MG/NOPB is a high-speed comparator manufactured by Texas Instruments, featuring Low Voltage Differential Signaling (LVDS) outputs. It operates within a supply voltage range of 3 V to 5.5 V and supports dual supplies from ±1.5 V to ±2.75 V. The device exhibits a propagation delay of 400 ps and a slew rate of 6000 V/µs. Input offset voltage is typically 2 mV, with an input bias current of 10 µA. It functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates LVDS-compatible differential outputs for high-speed signal transmission.
- Provides ultra-fast response characteristics with low propagation delay.
- Supports single or dual power supply configurations for flexible system integration.
Applications
- High-speed data acquisition systems
- Video signal processing circuits
- RF detection and demodulation
Procurement Notes
Verify the specific suffix MG against the official datasheet to confirm package type and tape/reel specifications. Ensure the NOPB designation confirms lead-free and RoHS compliance status as defined by the manufacturer. Cross-reference the part number with the latest revision history to validate electrical parameters and pinout compatibility before finalizing procurement orders.
Selection Notes
Select this component when differential signaling is required to minimize noise in high-frequency environments. Evaluate the LVDS output interface requirements against downstream receiver compatibility. Consider the 6000 V/µs slew rate for applications demanding rapid signal transitions without distortion.
Part Context
This device belongs to the LMH7220 family of high-speed comparators produced by Texas Instruments. It succeeds earlier National Semiconductor designs, maintaining performance standards while adhering to modern manufacturing processes. The MG package variant provides a compact solution for space-constrained printed circuit board layouts.
Replacement Considerations
Direct substitutes include the LMH7220MG and LMH7220. Verify functional equivalence regarding LVDS output levels and propagation delays before substitution.
