詳細介紹

1.1MHz, 70μA, CMOS RRIO Operational Amplifiers 

 

General Description 

The LTC8542 is a low voltage, micro power, CMOS voltage feedback dual operational amplifier. With an excellent bandwidth of 1.1MHz, a slew rate of 0.9V/μs, and a quiescent current of 70μA per amplifier at 5V, the LTC8542 can be designed into a wide range of applications.

 

The LTC8542 op-amp is specifically designed for general-purpose applications with optimal performance. It has a wide input common-mode voltage range and output voltage swing, and the maximum input offset voltage are 3.5mV. This part provides rail-to-rail output swing into heavy loads. The LTC8542 is specified for single or dual power supplies of +2.3V to +6.0V. All models are specified over the extended industrial temperature range of −40℃ to +125℃.

 

The LTC8542 is available in 8-lead DFN2x2, MSOP and SOIC packages.
