An aerospace ‘MILSPEC’ part with a national stock No. NSN : 5962-01-055-7666 

A NATO Stock Number, or National Stock Number (NSN) as it is known in the US, is a 13-digit numeric code, identifying all the ‘standardised material items of supply’ as they have been recognized by all NATO countries including United States Department of Defense.

George A. Philbrick was an American engineer. He was responsible, through his company George A. Philbrick Researches (GAP/R),^[1] for the 1953 commercialization and wide adoption of operational amplifiers, a now-ubiquitous component of analog electronic systems, and the invention and commercialization of electronic analog computers based on the operational amplifier principle. 

In 1953, George A. Philbrick Researches constructed the first commercially available operational amplifier using two tubes. Philbrick was later acquired by Teledyne.

The TP1322 operational amplifier belongs to a series of operational amplifiers known as “optimized 741s.” The TP1321 and TP1322 share a datasheet that describes them as “high slew rate operational amplifiers.” The TP1322’s slew rate is typically 80V/µs. The TP1321 is significantly slower at 20V/µs. The datasheet specifies a bandwidth of up to 20MHz for the TP1322, while the TP1321’s supports up to 33MHz (theoretical value of Gain*Bandwidth=100MHz at A=3). If you want to achieve high output levels, you should use the TP1322. For high bandwidth, the TP1321 is preferable.

The operational amplifier operates stably up to a gain of 10; below this value, the bandwidth must be limited with a capacitor at pin 8. Pin 8 is very sensitive. If you want to achieve the maximum bandwidth, the datasheet recommends cutting off the pin near the case to keep the parasitic capacitance low.

The TP1322’s bias current is typically 100nA, which is low for this class of operational amplifier. The supply voltage can be between +/-8V and +/-20V. The 1972 Teledyne Philbrick catalog lists a price of $20. Today (2022), that’s equivalent to $140.

PLEASE NOTE!

These parts came to us as part of a lot of surplus stock from a large Milspec type OEM and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however pristine having been properly packed, in an antistatic material, the photographs are representative of their excellent condition, being of some of our actual stock, and, as with all our products they come with a full guarantee. 

If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
