- High-Voltage Signal Conditioning for Low Voltage ADCsPDF, 135 Kb, 档案已发布: Jun 15, 2004
Analog designers are frequently required to develop circuits that convert high-voltage signals to levels acceptable for low-voltage data converters. This paper describes several solutions for this common task using modern amplifiers and typical power supplies. Five examples of conditioning ±10V bipolar signals for low-voltage single-rail analog-to-digital converters(ADCs) are presented: - High-Voltage Signal Conditioning for Differential ADCsPDF, 125 Kb, 档案已发布: Jun 14, 2004
Analog designers are frequently required to convert high-voltage signals to levels acceptable to low-voltage data converters with differential inputs. This paper describes solutions for this common task using modern amplifiers and typical power supplies. Three examples of conditioning В±10V bipolar signals for low-voltage analog-to-digital converters (ADCs) are shown: a single-supply design, - Precision Absolute Value CircuitsPDF, 100 Kb, 档案已发布: Oct 2, 2000
You can build a precision absolute value circuit using two op amps and two precision resistors. If you use an op amp and an IC difference amplifier no user supplied precision resistors or resistor adjustments are required. Circuits shown are suitable for precision split supply operation and for single-supply operation. When used with a rail-to-rail op amp the single supply circuit can approach a - Offset Correction Methods: Laser Trim, e-Trim, and Chopper (Rev. A)PDF, 795 Kb, 修订版: A, 档案已发布: Jul 20, 2017

Have you ever had the experience of designing an analog gain block with an amplifier that is specified to be unity gain stable only to find that it is oscillating out of control in your circuit? Or have you ever replaced a stable voltage feedback amplifier with a current feedback amplifier to find that the current feedback amplifier immediately oscillates when placed in the amplifier socket? Oscil - Op Amp Performance AnalysisPDF, 76 Kb, 档案已发布: Oct 2, 2000
This bulletin reflects the analysis power gained through knowledge of an op amp circuit's feedback factor. Feedback dictates the performance of an op amp both in function and in quality. The major specifications of the amplifier descibe an open-loop device awaiting feedback direction of the end circuit's function. Just how well the amplifier performs the function reflects through the feedback inte - Single-Supply Operation of Operational AmplifiersPDF, 77 Kb, 档案已发布: Oct 2, 2000
Operation of op amps from single supply voltages is useful when negative supply voltages are not available. Furthermore, certain applications using high voltage and high current op amps can derive important benefits from single supply operation.
