Description
The ROB3028 is a cascode differential 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 MP-48 and TO-116 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 |
| 3028 | identification number |
The Agenda radioelectronistului (2nd edition, 1989) gives the parameters of the ROB3028 in the table of audio-, low- and video-frequency (AF/JF/VF) amplifiers 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.
