High Temperature Dual Precision Operational Amplifier

Manufacturer's part number :


Manufacturer Honeywell

Honeywell - Magnetic

Description :

The HTOP01 is a precision low power operational amplifier, offering very low input offset voltage and drift over an operating temperature range of -55°C to 225°C. Using auto-zeroing techniques input offset voltage is continuously sampled and compensated, providing near perfect offset voltage compensation over temperature and time.

The internal auto-zero clock generator produces a pseudo-random clock frequency operating between 2kHz - 4kHz that effectively spreads out the clock noise frequency spectrum over a 2kHz span. This greatly reduces detectable clock noise in the amplifier's output spectrum.
