CXA1547Q

The CXA1547Q is designed as one kind of high speed and low noise transimpedance amplifier which particularly suitable for signal recovery in fiber-optic receivers. Typical applications include fiber-optic receiver and instrument. It structure is bipolar silicon monolithic IC.

CXA1547Q has six features. (1)High speed bipolar process provides for ultra high speed operation. (2)High transimpedance which would be typ 14k. (3)Wide band width which would be typ 250MHz. (4)Low noise at 10MHz would be 1.2pA/Hz. (5)Low power consumption which would be typ 24mW. (6)Single power supply which would be Vcc=Vcca=GND and Vee=-5.2V for negative supply and it would be Vcc=Vcca=+5V and Vee=GND for positive supply.

Some absolute maximum ratings of CXA1547Q have been concluded into several points as follow. (1)Its supply voltage would be from -0.3V to 7.0V. (2)Its minimum input voltage would be Vee-2.0V. (3)Its input voltage would be from -70uA to +70uA. (4)Its output current continuous would be from 0 to 50mA. (5)Its output current surge would be from 0 to 100mA. (6)Its operating case temperature range would be from -55°C to 125°C. (7)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of CXA1547Q are concluded as follow. (1)Its supply current would be min -3.2mA and typ -2.1mA and max -1.2mA. (2)Its DC transimpedance would be min 10k and typ 14.0k and max 18.0k. (3)Its maximum input current would be min 40mA. (4)Its input bias voltage would be typ Vee+0.77V. (5)Its output bias voltage would be typ Vee+1.06V. (6)Its input capacitance would be typ 1.0pF. (7)Its AC transimpedance would be min 10k and yp 14k ad max 18k. (8)Its bandwidth -3dB would be min 200MHz and typ 250MHz. (9)Its input current noise spectral density would be typ 1.2pA/Hz. And so on.
