DATASHEET ISL55210 FN7811 Rev 2.00 Wideband, Low-Power, Ultra-High Dynamic Range Differential Amplifier Jun 6, 2013 The ISL55210 is a very wide band, Fully Differential Amplifier Features (FDA) intended for high dynamic range ADC input interface Gain Bandwidth Product 4.0GHz applications. This voltage feedback FDA design includes an independent output common mode voltage control. Input Voltage Noise . 0.85nV/(Hz) Intended for very high dynamic range ADC interface Differential Slew Rate . 5,600V/s applications, at the lowest quiescent power (115mW), the 2V , 2-tone IM3 (200) 100MHz -109dBc P-P ISL55210 offers a 4.0GHz Gain Bandwidth Product with a very Supply Voltage Range 3.0V to 4.2V low input noise of 0.85nV/(Hz). In a balanced differential I/O configuration, with 2V output into a 200 load configured Quiescent Power (3.3V Supply) 115mW P-P for a gain of 15dB, the IM3 terms are <-100dBc through 110MHz. With a minimum operating gain of 2V/V (6dB), the Applications ISL55210 supports a wide range of higher gains with minimal Low Power, High Dynamic Range ADC Interface BW or SFDR degradation. Its ultra high differential slew rate of Differential Mixer Output Amplifier 5,600V/s ensures clean large signal SFDR performance or a fast settling step response. SAW Filter Pre/Post Driver The ISL55210 requires only a single 3.3V (max 4.2V) power Differential Comms-DAC Output Driver supply with 35mA typical quiescent current. This industry leading low current solution can be further reduced when Related Products and needed using the optional power shutdown to <0.4mA supply Literature current. External feedback and gain setting resistors give ISL55211 - Fixed Gain Version of the ISL55210 maximum flexibility and accuracy. A companion device, the ISL55211, includes on-chip feedback and 3 possible gain ISLA112P50 - 12-bit, 500MSPS ADC (<500mW) setting connections where an internally fixed gain solution is ISLA214P50 - 14-bit, 500MSPS ADC (<850mW) preferred. The ISL55210 is available in a leadless, 16 Ld TQFN package and is specified for operation over the -40C to +85C AN1649 - Designers Guide to the ISL55210 and ISL55211 ambient temperature range.
