产品概述 返回TOP
Despite being low cost, the CXAO42159A/B/C/D/E provide excellent overall performance. They offer wide gainbandwidth product to 50MHz and a typical low power of 2.3mA/amplifier.
The CXAO42159A/B/C/D/E‘s low distortion and fast settling make them ideal for buffering high speed A/D or D/A converters. The CXAO42159C/E has a power-down disable feature that reduces the supply current to 75μA/amplifier. These features make the CXAO42159C/Eideal for portable and battery-powered applications where size and power are critical. All are specified over the extended -40℃ to +125℃temperature range.
