Wideband differential amplifier
01 November 2011
Intersil’s ISL55211 wideband differential amplifier features industry’s lowest distortion.
ISL55211 from Intersil is a low noise, wideband differential amplifier that requires only a single 3.3V power supply and consumes only 35mA quiescent current (155mW).
The ISL55211 is an ultra-low distortion, high-speed differential amplifier that can drive high performance ADCs, such as the recently introduced 14-bit ISLA214P50, with minimal degradation to the ADC’s baseline performance. It provides three fixed gain settings of 2x, 4x, and 5x, and maintains a constant 1.4 GHz bandwidth and low output noise of <10nV/√Hz for all gain settings.
It requires only a single 3.3V power supply and consumes 35mA quiescent current (155mW). A power shutdown feature reduces the supply current to less than 400microAmps while biasing the outputs at the common mode voltage, protecting attached ADCs from damage and reducing transient recovery time when exiting the shutdown mode. It is suitable for applications that require a fixed gain amplifier to drive high-speed ADCs in data acquisition systems, instrumentation systems, and communications equipment. The ISL55211 is the second in Intersil’s family of differential amplifiers, joining the ISL55210 released earlier this year.
The ISL55211 is available now in a 16-pin, 3mm x 3mm TQFN package.
