Wideband, Low Noise, Low Distortion, Fixed Gain,
Differential Amplifier
ISL55211
The ISL55211 is a wideband, differential input to differential
output amplifier offering 3 possible internal gain settings.
Using fixed 500internal 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.
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.
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 2VP-P 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.
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
range.
