LT1128ACN8#PBF: Application Field and Working Principle

The LT1128ACN8#PBF is a high-performance, low-power operational amplifier used in instrumentation, analog-to-digital (A/D) conversions, and similar applications. It is a precision operational amplifier with a low-noise and low-offset differential amplifier stage. This is a JFET op-amp with bandwidth approaching 5MHz, low offset voltage and drift, low-input bias current, and low-input voltage noise. It offers excellent device matching for additive and subtractive current-to-voltage (V/I) converters, low-power A/D converters, and other multiplexers, while conserving power.

The LT1128ACN8#PBF offers an extremely low input offset voltage of 0.1mV max and 0.05mV/V typical with a maximum temperature drift range of 1μV/°C max. This is easy to accomplish with a low-noise, high-linearity op amp such as the LT1128ACN8#PBF. A wide power supply range of ±2.7 Volts to ±18 Volts and rail-to-rail output swing are possible with the LT1128ACN8#PBF.

The LT1128ACN8#PBF is a dual-channel amplifier with a single-ended input. It can be used as an operational amplifier or comparator. With a low noise of 2.5 nV/rt Hz, the LT1128ACN8#PBF is ideal for applications where accuracy and noise performance are important. It also features a wide common-mode input voltage range, up to 24V, so it can be used in applications where the input signal may follow a wide range of conditions.

The LT1128ACN8#PBF works on the principle of a differential amplifier. The differential amplifier provides high gain and high gain-bandwidth product. It amplifies the difference between two input signals, whichever side has more voltage wins and the output will swing in the same direction as the higher voltage side. The LT1128ACN8#PBF differential amplifier also compensates for common mode errors such as temperature and supply voltage variation.

The LT1128ACN8#PBF is an ideal choice for precision instrumentation, data acquisition and system control, A/D converters, multiplexers, and low-noise amplifiers. It is also an excellent amplifier for very low-noise, low-power applications. With its wide common mode input voltage range, low cut-off frequency, and low offset voltage, the LT1128ACN8#PBF can be used in a variety of applications requiring precision and low-noise performance.
