The AD8271 low-distortion, programmable-gain difference amplifier comprises a precision op-amp and seven laser-trimmed gain-setting resistors, enabling user-selectable differential gains of 0.5, 1, or 2. It can also be configured in over 40 single-ended configurations, with gains ranging from –2 to +3. Two grades are available: the B-grade specifies 0.02% max gain error, 2-ppm/°C max gain drift, 600-µV max offset, and 80-dB min common-mode rejection; the A-grade specifies 0.05% max gain error, 10-ppm/°C max gain drift, 1000-µV max offset, and 74-dB min common-mode rejection. Both grades specify –110-dB harmonic distortion, 15-MHz bandwidth, and 30-V/µs slew rate. This combination of speed and precision makes the device ideal for driving ADCs, building instrumentation amplifiers, level shifting, and automatic test equipment. Operating on a single 5V to 36V supply or dual ±2.5V to ±18V supplies, the AD8271 draws 2.3 mA. Datasheet |
