MICROPOWER SOT23 AMPLIFIERS OFFER 54 FIXED-GAIN VERSIONS
SUNNYVALE, CA-July 30, 1999-Maxim Integrated Products introduces the MAX4074/MAX4075 single/dual, micropower, fixed-gain GainAmp™ amplifiers with on-chip gain-setting resistors. These amplifiers offer a choice of 27 inverting and 27 noninverting factory-trimmed gains, and they replace an amplifier and two resistors with a single SOT23-5 (3mm x 3mm) package. Applications like ADC amplifiers and Sallen-Key filters benefit from excellent resistor matching that provides 0.1% total gain accuracy while minimizing the size and cost of circuit layout.
The MAX4074/MAX4075 provide 27 inverting gains from -0.25V/V to -100V/V and 27 noninverting gains from +1.25V/V to +101V/V. They operate from a single +2.5V to +5.5V supply. By optimizing frequency compensation for high-gain versions, these devices achieve exceptional gain-bandwidth (GBW) products as high as 4MHz while drawing only 34µA supply current. They also feature high-voltage input fault protection, which allows operation with either input voltage as high as ±17V without excessive current draw. The outputs of these devices can swing Rail-to-Rail® and maintain DC accuracy while driving 10k ohm loads. Each amplifier is stable for capacitive loads up to 500pF.
The single, micropower, fixed-gain GainAmp amplifier (MAX4074) is available in the compact SOT23-5 package. The dual amplifier (MAX4075) is available in space-saving 8-pin µMAX and 8-pin SO packages. Prices start from $0.68 (1000-up, FOB USA).
