- 1.2µA Max Quiescent Current per Amplifier
- +2.5V to +10V Single-Supply Range
- 500µV Max Offset Voltage (MAX406A/MAX409A)
- < 0.1pA Typical Input Bias Current
- Output Swings Rail-to-Rail
- Input Voltage Range Includes Negative Rail
The common-mode input-voltage range extends from the negative rail to within 1.1V of the positive supply (for the singes, 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 unity-gain stable with a 5V/ms typical slew rate and an 8kHz gain bandwidth. Connecting BW to V+ puts the MAX406 into decompensated mode with a 20V/ms typical slew rate and a 40kHz gain bandwidth (AVCL ≥ 2V/V).
The dual MAX407 and quad MAX418 are internally compensated to be unity-gain stable. The MAX409/MAX417/MAX419 single/dual/quad op amps feature 150kHz typical bandwidth, 75V/ms slew rate, and stability for gains of 10V/V or greater.
