Op－amp reduces size, improves accuracy of analysis instruments

Chemical analysis instruments can achieve the highest level of precision and data repeatability over a wider temperature range, in a compact form factor, says Analog Devices, which has introduced the ADA4530-1 which achieves this with an input bias current that is claimed to be at least 20 times lower than competing devices.

The low bias current makes the amplifier suitable for interfacing to sensors that are sensitive to output loading such as photo diodes and other high output impedance sensors often used in precision monitoring/analysis equipment such as spectrophotometers, chromatographs and mass spectrometers, as well as potentiostatic and amperostatic coulometry measurement devices.

The amp also can be used as a front-end amplifier for picoammeter and coulombmeter instrumentation systems, as a transimpedance amplifier for photodiodes, ion chambers, and working electrode measurements, or as a high-impedance buffer for chemical and capacitive sensors.

Input bias current is 250 fA at 125°C, and drops to 20 fA at 85°C, which is 50 times lower than competing devices, says the company. It is also claimed to be the only op amp able to specify the same input bias current of 20 fA from room temperature to 85°C and is the only amp in its class to be fully production tested for bias current at room temperature and 125°C to take advantage of the sensitivity of sensors.

An on-chip guard buffer tracks the input common-mode voltage and provides an output that is useful for driving PCB guard rings or the guard shield of interconnecting shielding to reduce the effects of stray capacitance on the sensitive connections between the sensor and the amplifier. This removes the need for the customer to design a separate circuit to provide the required output drive, reducing design time, cost, and PCB space.

Available in an eight-lead SOIC, an evaluation board is also available

运算放大器缩小了分析仪器的尺寸，提高了准确度

化学分析仪器能够达到的精度和可重复性的数据在更宽的温度范围内的最高水平，在一个紧凑的外形，说ADI公司，已经推出了用于实现这一功能的输入偏置电流，自称是在ADA4530-1至少20倍，比同类器件降低。

低偏置电流，使合适的放大器，用于连接到传感器对输出负载敏感，例如光电二极管和经常用于精密监测/分析设备，如分光光度计，色谱仪和质谱仪其他高输出阻抗的传感器，以及电位和amperostatic库仑测量设备。

放大器也可作为一个前端放大器对皮安计和库仑仪表系统，作为阻放大器为光电二极管，离子腔室，和工作电极的测量，或者作为用于化学和电容式传感器的高阻抗缓冲器。

输入偏置电流为250为fA在125℃，降至20为fA在85°C，比同类竞争器件低50倍，说公司。它也声称自己是唯一的运算放大器能够指定相同的输入偏置电流的20为fA从室温到85°C，是同类产品中唯一放大器在室温和125°得到充分的生产测试偏置电​​流C到取传感器的灵敏度的优点。

片上后卫缓冲器跟踪输入共模电压，并提供一个输出，用于驱动印刷电路板的保护环或互连屏蔽，以减少杂散电容对传感器和放大器之间的敏感的连接作用的护罩是有用的。这消除了需要在顾客设计一个独立的电路来提供所需的输出驱动器，减少了设计时间，成本和PCB空间。

可在八引脚SOIC，评估板也已推出。
