HIGH TEMPERATURE QUAD ULTRALOW
INPUT BIAS CURRENT OPERATIONAL AMPLIFIER
HT1104Z
The HT1104Z 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 HT1104Z 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 HT1104Z.
The HT1104Z is an option of the HT1104 with the ESD
protection circuitry removed to achieve high input imped-
ance. This higher impedance also provides the HT1104Z
with an ultra-low bias current.
