1 / 6 page  High Temperature Dual Precision Operational Amplifier HTOP01 DESCRIPTION The HTOP01 is a precision low power op amp, 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. An internal oscillator and logic provides all necessary auto-zero clock signals, and no external capacitors are needed. 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 cloc k noise in the amplifier’s output spectrum. Additionally, an external clock input pin (XCLK) is provided along with a select input pin (SEL) to choose between the internal clock and an optional external clock. The external clock option allows timing flexibility for synchronously sampled systems, where no clock energy can be tolerated in the sampled amplifier output. To save power, a power shutdown pin (SHDN) de- powers all analog circuitry when asserted (active high). The current with SHDN asserted is <150 A over temperature.
