Product details

TO-99-8 metal can — hermetic, through-hole, retrofit-ready

Housed in a TO-99-8 metal can, the LF298H is a through-hole device suited for environments where hermetic sealing matters — avionics, downhole instrumentation, or legacy board repairs where a drop-in replacement is preferred over a surface-mount adapter. The metal can provides a rugged, shielded enclosure that resists moisture and mechanical stress better than plastic DIP or SOIC alternatives.

What a sample-and-hold IC does on your board

The LF298H is a monolithic sample-and-hold circuit. It captures an analog voltage on command and holds it steady on an external capacitor while an ADC or downstream circuit digitises or processes it. This function is common in data-acquisition front ends, multiplexed analog systems, and precision measurement chains where timing skew between channels must be eliminated.

Frequently asked questions

What is the LF298H datasheet and where can I find it?

Engineers need the datasheet to verify pinout, electrical specs, and application circuits before design-in.

What is the pinout of the LF298H TO-99 package?

Designers and technicians must know the correct pin connections to ensure proper circuit integration.

Where can I buy LF298H in stock?

Buyers need to quickly locate inventory to cover BOM requirements and avoid project delays.

What is the price of LF298H?

Sourcing buyers need pricing for budgeting and cost comparisons across distributors.

What are the equivalents or replacements for LF298H?

When parts are unavailable or obsolete, engineers and brokers seek drop-in replacements to maintain production.

Is LF298H still active or is it obsolete?

Lifecycle status affects long-term availability and risk of EOL; buyers need to know before committing.
