Capacitive load drive is one of the most common causes of operational amplifier stability issues. The load capacitance, CL, interacts with the open-loop output impedance of the amplifier, ZO, by adding a single or double pole in the open-loop response. The additional pole or poles degrades the circuit phase margin, resulting in transient overshoot and ringing, ac gain peaking - System Noise Analysis of a Resistive Bridge Pressure Sensor Connected to the PGAPDF, 195 Kb, File published: Jul 7, 2015
In this application note we will do a system noise analysis of the PGA900 connected to a resistive bridgepressure sensor. First, we will measure the noise referred to the output for the PGA900. Then, using these measurement results we will calculate the noise-free resolution and effective resolution of the PGA900 forits analog-to-digital converter operating at 64- and 128-Вµs output data - PGA900 as 4- to 20-mA Current Loop TransmitterPDF, 238 Kb, File published: May 7, 2015
This application note shows the PGA900 used as a 2-wire, 4- to 20-mA current loop transmitter, a common method of transmitting sensor information in industrial process-monitoring applications. Transmitting sensor information (physical parameter measurements) through a current loop is particularly useful when the information must be sent to a remote location over long distances (1000 feet or more). - Understanding Open Loop Output Impedance of the PGA900 DAC Gain Amplifier (Rev. A)PDF, 253 Kb, Revision: A, File published: May 19, 2015
The open-loop output impedance (ZO) of an operational amplifier is one of the most important specifications. Proper understanding of ZO over frequency is crucial for the understanding of loop gain, bandwidth, and stability analysis.This application note provides an in-depth understanding of the PGA900 ZO magnitude over frequency.

- Connecting PGA900 Instrumentation Amplifier to Resistive Bridge SensorPDF, 1.1 Mb, File published: May 8, 2015
Understanding the input and output limitations of an instrumentation amplifier (IA) is important in interfacing a resistive bridge sensor to the PGA900. Adjusting the common mode voltage of the input signal appropriately allows us to maximize the gain. Maximizing the gain yields the largest output signal span for the 24-bit analog-to-digital converter (ADC). The largest signal span maximizes the c - Understanding Open Loop Gain of the PGA900 DAC Gain AmplifierPDF, 338 Kb, File published: Apr 2, 2015
The open-loop gain (AOL) of an operational amplifier is one of the most important specifications. Proper understanding of AOL at DC and over frequency is crucial for the understanding of closed-loop gain, bandwidth, and stability analysis.This application note provides an in-depth understanding of the PGA900 AOL magnitude and phase over frequency.
