产品概述 返回TOP
The CXAO42137A/CXAO42137C(single), CXAO42137B (dual), CXAO42137D (quad) are rail-to-rail output voltage feedback amplifiers offering ease of use and low cost. They have bandwidth and slew rate typically found in current feedback amplifiers. All have a wide input common mode voltage range and output voltage swing, making them easy to use on single supplies as low as 2.5V.Despite being low cost, the CXAO42137A series provide excellent overall performance. They offer wide bandwidth to 350MHz (G = +1) along with 0.1dB flatness out to 125MHz (G = +1) and offer a typical low power of 4.3mA/amplifier.The CXAO42137A series are low distortion and fast settling make them ideal for buffering high speed A/D or D/A converters. The CXAO42137C has a power-down disable feature that reduces the supply current to 75μA. These features make the CXAO42137C ideal for portable and battery-powered applications where size and power are critical. All are specified over the extended -40℃ to +125℃ temperature range.
