(FDA) intended for high dynamic range ADC input interface

applications. This voltage feedback FDA design includes an

independent output common mode voltage control.

Intended for very high dynamic range ADC interface

applications, at the lowest quiescent power (115mW), the

ISL55210 offers a 4.0GHz Gain Bandwidth Product with a very

low input noise of 0.85nV/√(Hz). In a balanced differential I/O

configuration, with 2VP-P output into a 200? load configured

for a gain of 15dB, the IM3 terms are <-100dBc through

110MHz. With a minimum operating gain of 2V/V (6dB), the

ISL55210 supports a wide range of higher gains with minimal

BW or SFDR degradation. Its ultra high differential slew rate of

5,600V/μs ensures clean large signal SFDR performance or a

fast settling step response.

The ISL55210 requires only a single 3.3V (max 4.2V) power

supply with 35mA typical quiescent current. This industry

leading low current solution can be further reduced when

needed using the optional power shutdown to <0.4mA supply

current. External feedback and gain setting resistors give

maximum flexibility and accuracy. A companion device, the

ISL55211, includes on-chip feedback and 3 possible gain

setting connections where an internally fixed gain solution is

preferred. The ISL55210 is available in a leadless, 16 Ld TQFN

package and is specified for operation over the -40oC to +85oC

ambient temperature range.
