THS6032CVFP Working Principle

The THS6032CVFP is a low-noise, low-power, rail-to-rail CMOS operational amplifier, built on standard low-voltage CMOS logic. The device is optimized to achieve low-noise, low-distortion, and rail-to-rail performance. This device is unique in that it has two modes — normal mode, and power save mode — which make it ideal for applications that require low power and good performance.

The device is suitable for use in applications such as medical monitoring, bio-sensing, precision analog-to-digital converters, digital-to-analog converters, and CMOS imaging systems. The device features rail-to-rail input and output, low distortion, low offset voltage, low power, a power save mode, and good PSRR and CMRR. The THS6032CVFP is compatible with industry-standard CMOS processes.

The device operates from a single 1.8V to 3.6V supply and has a maximum power supply rejection ratio (PSRR) of -40 dB. The device is capable of driving a 300pF capacitive load with a gain bandwidth product of 6.7MHz and a slew rate of 1.9V/µs. The device has three low-noise modes, two of which are operated through control pins. The device has a low-noise current-feedback amplifier and an adjustable user-defined low-noise bandpass filter.

The THS6032CVFP utilizes an output stage that is designed to provide the best combination of low distortion and rail-to-rail output swing. The output stage is designed to receive signals from the low-noise current-feedback amplifier and then drive a load of up to 300pF, with a slew rate of 1.9V/µs. The output stage also has three low-noise modes which can be adjusted by the user.

In addition, the THS6032CVFP includes a power save mode that reduces power consumption when normal operation is not required. The power save mode reduces the quiescent current to just 20nA, while still maintaining the low-noise performance and rail-to-rail output swing.
