Analog Devices Inc. GAP01FP

The GAP-01 combines two differential-input transconductance amplifiers, two low-glitch current-mode switches, a voltage-output buffer and a precision comparator. Digital channel selection routes either input path, combines them, or holds the previous output with an external hold capacitor. Feedback components determine the channel gain and polarity.

The original ordering table identifies GAP01FP as a plastic commercial device, and the package data specify an 18-pin DIP (P). The LCDChip package registry maps the database entry 18-DIP (0.300", 7.62mm) to 18-DIP.jpg. Verify lead pitch, body width and pin-one orientation against the manufacturer's outline before PCB work.

Layout checks

• Confirm the plastic 18-pin DIP footprint and notch orientation.
• Place feedback and hold-capacitor components near their device pins.
• Keep sensitive analog inputs separated from channel-control transitions.

The registered local package JPG is missing; this draft must remain unpublished until it is supplied and checked.

The original PMI pin-connections list identifies these GAP-01 functional pins. Confirm the package-view orientation in the datasheet before wiring.

External component connections and comparator output behavior must be taken from the complete manufacturer circuit diagram, not inferred from this summary.

Values are from the PMI GAP-01 Rev. A ordering and absolute-maximum tables. Use the electrical-characteristics table and its test conditions for design limits.

The related GAP01EP is an E-grade plastic part in the original ordering table, with different offset-voltage and zero-scale-error classes. It must not be treated as an automatic drop-in substitute. Compare grade limits, temperature range, channel-control behavior, external feedback, hold capacitor, comparator connections and footprint before considering any replacement.

No internal product link is presented because a fully verified electrical replacement and exact matching LCDChip product URL have not been established.

The original GAP-01 Rev. A documentation was issued by Precision Monolithics Inc. in 1986 and lists GAP01FP in its plastic commercial ordering column. LCDChip catalogs the part under Analog Devices Inc.; confirm actual device markings, original maker and lifecycle documentation with the supplying channel.

For this legacy part, inspect package marking, lot traceability, storage history and ESD handling. The catalog's stock and price are not a verified live distributor quotation; request exact-part availability and quantity-break pricing before purchase.

Validate the supply and input ranges under the full datasheet test conditions, the channel truth table, external feedback and hold capacitor, comparator interface, thermal limits and 18-pin DIP footprint. Publication is blocked pending the package JPG and dependable current stock and tier-price confirmation.
