Description

The ROB3080 is an operational transconductance amplifier, an analog integrated circuit listed in the Agenda radioelectronistului (2nd edition, 1989) among the integrated circuits made in Romania by ICCE (CCSIT-CE), in TO-116, TO-99 and MP-48 packages [1]. Its pinout is in the Gallery.

Coded as (Romanian system, internal CCSIT-CE code) [2]:

Part Meaning
RO manufacturer’s code: RO (Romania)
B bipolar integrated circuit
3080 identification number

The Agenda radioelectronistului (2nd edition, 1989) gives the parameters of the ROB3080 in the table of operational amplifiers and voltage comparators made in Romania by IPRS Băneasa and CCSIT-CE (section 35.3) [3]: absolute maximum ratings and electrical characteristics over the full temperature range; they are in the specifications.

Notes on the table of section 35.3 [3]: Values printed with „<” (maximum) or „>” (minimum) are given here without the sign: „<” for VIO, IIO and IIB. The gain column gives, with a footnote, the large-signal transconductance gm (13·10³ µA/V).
