Description

The ROB709 is a general-purpose operational 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 a TO-116 package [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
709 identification number

The Agenda radioelectronistului (2nd edition, 1989) gives the parameters of the ROB709 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.
