ADA4523-1是一款高电压、低噪声、零漂移运算放大器,可在4.5 V至36 V宽电源范围内提供精密直流性能。失调电压和1/f噪声得到抑制,使该放大器能够实现最大±4 µV的失调电压以及88 nV p-p(典型值)的0.1 Hz至10 Hz输入噪声电压。ADA4523-1的自校准电路在0.01 µV/°C(最大值)温度下具有低失调电压漂移以及随时间而变化的零点漂移。此外,ADA4523-1利用片内滤波实现较高的抗电磁干扰(EMI)能力。
宽电源范围与低噪声、低失调、168 dB电源抑制比(PSRR)和160 dB共模抑制比(CMRR)相结合,使ADA4523-1非常适合高动态范围测试、测量和仪器仪表系统。

EVAL-ADA4523-1:ADA4523-1 Evaluation Board
The EVAL-ADA4523-1ARMZ allows the evaluation of the ADA4523-1 single-channel, 8-lead, micro small outline package (MSOP) operational amplifier. The ADA4523-1 in this evaluation board is configured as a noninverting amplifier with a gain of 101. The ADA4523-1 has a typical gain bandwidth product of 4 MHz. When using a gain of 101, the useable bandwidth of the ADA4523-1 is limited to approximately 39.6 kHz. This limitation in bandwidth acts as a low-pass filter that rejects the artifacts generated by the 330 kHz internal chopping frequency of the ADA4523-1.
The EVAL-ADA4523-1 layout lessens the thermocouple effects of the trace and components that introduce offset voltages greater than the maximum offset voltage of the ADA4523-1 by carefully constructing the nodes connected to the inverting and noninverting inputs. The ADA4523-1 also features a shutdown mode for low power applications. Test point provisions for the SD and SD_COM pins are placed on the EVAL-ADA4523- 1ARMZ to easily use the shutdown function.
The EVAL-ADA4523-1ARMZ mainly consists of 0805 sized resistors and capacitors to ensure simple installation except for the bypass capacitors. The 10 µF bypass capacitors (C1 and C4) have a 2220 package size to accommodate a higher voltage rating because the ADA4523-1 has a maximum supply of 55 V. For full details on the ADA4523-1, see the ADA4523-1 data sheet, which must be consulted in conjunction with this user guide when using the EVAL-ADA4523-1ARMZ.
