MAX9622

Precision, High-Bandwidth Op Amp

Detailed Description

The MAX9622 is a power-efficient, high-speed op amp ideal for capturing fast edges in a wide variety of signal processing applications.

It precisely calibrates its VOS on power-up to eliminate the effects of package stresses, power supplies, and temperature.

Applications Information

Power-Up Autotrim

The MAX9622 features power-up autotrimming that allows the devices to achieve less than 100µV of input offset voltage. The startup sequence takes approximately 4ms to complete after the supply voltage exceeds an internal threshold of 1.8V. During this time, the inputs and outputs are connected to an auxiliary amplifier that has an input offset of 5mV (typ). As soon as the autotrimming is completed, the inputs and outputs switch from the auxiliary amplifier to the calibrated amplifier. The calibration settings hold until the supply voltage drops below an internal threshold of 1.4V. This could be used to recalibrate the amplifier. The supply current of the part increases to about 2.5mA during the power-up autotrim period. Use good supply decoupling with low ESR capacitors.

Active Filters

The MAX9622 is ideal for a wide variety of active filter circuits that make use of their wide output voltage swings and large bandwidth capabilities. The Typical Application Circuit shows a multiple feedback active filter circuit example with a 100kHz corner frequency. At low frequencies, the amplifier behaves like a simple low-distortion inverting amplifier gain = -1, while its high bandwidth gives excellent stopband attenuation above its corner frequency. See the Typical Application Circuit.

Input Differential Voltage Protection

During normal op-amp operation, the inverting and noninverting inputs of the MAX9622 are at essentially the same voltage. However, either due to fast input voltage transients or due to loss of negative feedback, these pins can be forced to different voltages. Internal back-to-back diodes and series resistors protect input-stage transistors from large input differential voltages (see Figure 2).

IN+ and INcan survive any voltage between the powersupply rails.

This op amp has been designed to exhibit no phase inversion to overdriven inputs.
