超低功耗，低失真 Ultralow Power, Low Distortion
The is an evaluation board for ADA4940-2 low noise, low distortion differential amplifiers with very low power consumption. This evaluation board aids in the testing of the ADA4940-2 dual high speed differential amplifier. The ADA4940-2ACP-EBZ is a bare board, that is there are no components soldered to the board. This enables users to customise the circuit and quickly prototype a variety of differential amplifier circuits, which minimizes risk and reduces time to market. This evaluation board will also support any of the Analog Device"s, ADA49XX series of dual high speed differential amplifiers. They are an ideal choice for driving low power, high resolution, high performance SAR and sigma-delta Σ-Δ analog to digital converters ADCs with resolutions up to 18bits from dc to 1MHz on only 1.25mA of quiescent current. The adjustable level of the output common mode voltage allows the ADA4940-2 to match the input common mode voltage of multiple ADCs.
