Renesas Electronics Corporation Wideband, Low Noise, Low Distortion, Fixed Gain, Differential Amplifier ISL55211IRTZ-T7A

The ISL55211 is a wideband, differential input to differential output amplifier offering 3 possible internal gain settings. Using fixed 500? internal feedback resistors, the amplifier may be configured for a differential gain of 2, 4 or 5V/V depending on which combination of input pins are connected to the signal source. Internal feedback capacitors controls the signal bandwidth to be a constant 1.4GHz in all gain settings.brbr Ideally suited for AC-coupled data acquisition applications, the output DC common mode voltage is controlled through an external VCM pin or left to default to 1.2V above the negative supply pin. Where the differential signal source is AC-coupled, the input common mode voltage will equal the output common mode voltage.brbr Intended for very high dynamic range ADC interface applications, the ISL55211 offers 5600V/µs differential slew rate, 12nV/√Hz output noise, and 100dBc SFDR to 100MHz for 2VsubP-P/sub 2-tone 3rd order intermodulation. Its balanced architecture effectively suppresses even order distortion terms - an important issue for very wide band 1st Nyquist zone ADC interface applications. Minimum gain operation of 2V/V (6dB) with 1dB peaking ensures stable performance over-temperature. It's ultra high differential slew rate of 5600V/µs provides adequate performance margin for large signal application through 500MHz.brbr The ISL55211 requires only a single 3.3V (max. 4.2V) power supply and 35mA quiescent current, providing a very low power solution (115mW). Further power savings are possible using the optional power shutdown control - where the quiescent current can be reduced to 0.4mA. A companion device, the ISL55210, offers similar performance where the feedback and gain resistors are external. Both are available in a 16 Ld TQFN (Pb-free) package and are specified for operation over the -40°C to +85°C ambient temperature rang
