Description
The ROB01 is a series of hearing-aid amplifiers, analog integrated circuits listed in the Agenda radioelectronistului (2nd edition, 1989) among the integrated circuits made in Romania by ICCE (CCSIT-CE), in a TO-86 package [1]. Its codes (ROB01 and ROB02) are in the Variants table; the pinout is in the Gallery.
The 1st edition of the Agenda (1983) lists it in one row with the ROB02, „ROB 01*; 02*”, as a hearing-aid amplifier in a TO-86 package; the 2nd edition lists only the ROB01 [3].
Coded as (Romanian system, internal CCSIT-CE code) [2]:
| Part | Meaning |
|---|---|
| RO | manufacturer’s code: RO (Romania) |
| B | bipolar integrated circuit |
| 01 | identification number |
The Agenda radioelectronistului (2nd edition, 1989) gives the parameters of the ROB01 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) [4]: absolute maximum ratings and electrical characteristics over the full temperature range; they are in the Variants table.
Notes on the table of section 35.3 [4]: Values printed with „<” (maximum) or „>” (minimum) are given here without the sign: „<” for the distortion (d).
