Intersil's ISL55211 Wideband Differential Amplifier Features Industry's Lowest Distortion
October 18 2011 - 10:00AM
Marketwired
Intersil Corporation (NASDAQ: ISIL) has introduced the ISL55211, 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 1.4GHz
bandwidth and low output noise of < 10nV/√Hz for all gain
settings.
The ISL55211 requires only a single 3.3V power supply and
consumes only 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 an excellent design choice 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.
