ADA4927-2YCPZ-R7

ADA4927 is a low noise, ultralow distortion, high speed, current feedback differential amplifier that is an ideal choice for driving high performance ADCs with resolutions up to 16bits from dc to 100MHz. The output common-mode level can easily be matched to the required ADC input common-mode levels. The internal common-mode feedback loop provides exceptional output balance and suppression of even-order distortion products. Differential gain configurations are easily realized using an external feedback network comprising four resistors. The current feedback architecture provides loop gain that is nearly independent of closed-loop gain, achieving wide bandwidth, low distortion and low noise at higher gains and lower power consumption than comparable voltage feedback amplifiers. It is suitable for use in ADC drivers, single-ended-to-differential converters, IF and baseband gain blocks, differential buffers and differential line drivers applications.

• Wide supply operation: +5V to ±5V
• Externally adjustable gain
• Stability and bandwidth controlled by feedback resistor
• Differential-to-differential or single-ended-to-differential operation
• Adjustable output common-mode voltage
• Better distortion at higher gains than VF amplifiers
• High speed: slew rate: 5000V/µs typ at VOUT, dm = 2V step, 25% to 75%, ±5V operation
• Settling time to 0.1% is 10ns typ at VOUT, dm = 2V step, ±5V operation
• 24 lead LFCSP-EP package
• Operating temperature range from -40 to 105°C
