Product Descriptions
The MAX406/MAX407/MAX409/MAX417-MAX419 aresingle, dual, and quad low-voltage, micropower, precision op amps designed for battery-operated systems. They feature a supply current of less than 1.2uA per amplifier that is relatively constant over the entire supply range, which represents a 15 to 20 times improvement over industry-standard micropower op amps. A unique output stage enables these op amps to operate at ultra-low supply current while maintaining linearity under loaded conditions. In addition, the out-put is capable of sourcing 1.8mA when powered by a 9V battery.
The common-mode input-voltage range extends from the negative rail to within 1.1V of the positive supply (for the singles, 1.2V for the duals and quads), and the output stage swings rail-to-rail. The entire family is designed to maintain good DC characteristics over the operating temperature range, minimizing the input referred errors.
The MAX406 is a single op amp with two modes of operation: compensated mode and decompensated mode.Floating BW (pin 8) or connecting it to V- internally compensates the amplifier. In this mode, the MAX406 is unitygainstable with a 5V/ms typical slew rate and an 8 kHz gain bandwidth. Connecting BW to V+ puts the MAX406 into decompensated mode with a 20V/ms typical slew rate anda 40kHz gain bandwidth (AvCL > 2VN).
The dual MAX407 and quad MAX418 are internally com-pensated to be unity-gain stable. The MAX409/MAX417/MAX419 single/dual/quad op amps feature 150kHz typicalbandwidth, 75V/ms slew rate, and stability for gains of10VN or greater.
