Wideband, Low-Power, Ultra-High Dynamic Range Differential Amplifier ISL55210 Features The ISL55210 is a very wide band, Fully Differential Amplifier Gain Bandwidth Product 4.0GHz (FDA) intended for high dynamic range ADC input interface Input Voltage Noise . 0.85nV/(Hz) applications. This voltage feedback FDA design includes an Differential Slew Rate . 5,600V/s independent output common mode voltage control. 2V , 2-tone IM3 (200) 100MHz -109dBc P-P Intended for very high dynamic range ADC interface Supply Voltage Range 3.0V to 4.2V applications, at the lowest quiescent power (115mW), the ISL55210 offers a 4.0GHz Gain Bandwidth Product with a very Quiescent Power (3.3V Supply) 115mW low input noise of 0.85nV/(Hz). In a balanced differential I/O configuration, with 2V output into a 200 load configured P-P Applications for a gain of 15dB, the IM3 terms are <-100dBc through Low Power, High Dynamic Range ADC Interface 110MHz. With a minimum operating gain of 2V/V (6dB), the ISL55210 supports a wide range of higher gains with minimal Differential Mixer Output Amplifier BW or SFDR degradation. Its ultra high differential slew rate of SAW Filter Pre/Post Driver 5,600V/s ensures clean large signal SFDR performance or a Differential Comms-DAC Output Driver fast settling step response. The ISL55210 requires only a single 3.3V (max 4.2V) power Related Products and supply with 35mA typical quiescent current. This industry Literature leading low current solution can be further reduced when needed using the optional power shutdown to <0.4mA supply ISL55211 - Fixed Gain Version of the ISL55210 current. External feedback and gain setting resistors give ISLA112P50 - 12-bit, 500MSPS ADC (<500mW) maximum flexibility and accuracy. A companion device, the ISLA214P50 - 14-bit, 500MSPS ADC (<850mW) ISL55211, includes on-chip feedback and 3 possible gain setting connections where an internally fixed gain solution is AN1649 - Designers Guide to the ISL55210 and ISL55211 preferred. The ISL55210 is available in a leadless, 16 Ld TQFN Evaluation Boards package and is specified for operation over the -40C to +85C AN1725 - Ultra Low Power Broadband 8 to 14-Bit Data ambient temperature range.
