HIGH TEMPERATURE QUAD
OPERATIONAL AMPLIFIER
HT1104
The HT1104 monolithic quad operational amplifier is a
versatile performer over an extremely wide temperature
range. It is fabricated with Honeywell’s dielectrically iso-
lated high-temperature linear (HTMOS™) process, and is
designed specifically for use in systems operating in se-
vere high-temperature environments. All parts are burned
in at 250
°C to eliminate infant mortality.
These amplifiers provide guaranteed performance over
the full -55 to +225
°C temperature range. Typically, parts
will operate up to +300
°C for a year, with derated perfor-
mance. The HT1104 will operate with both single and split
supplies. High-temperature applications such as trans-
ducer interfacing, amplification, active filtering, and signal
buffering are all possible with the HT1104.
