3PEAK offers products around the signal chain like amplifiers, converters (ADCs and DACs), mixed signal components and communication ICs. After news about isolated transceivers, we would like to introduce the family of zero-drift operational amplifiers in more detail:
3PEAK offers a range of chopper-stabilized zero-drift operational amplifiers with a voltage supply up to a maximum of 5.5V. These can be powered with one or two supply voltages (up to 5.5V or ±2.75V).
Offering very low offset and offset drift values down to 5µV and 6nV/°C, along with high common mode rejection ratio (CMRR) up to 142dB, these operational amplifiers are ideal for applications such as
in industrial and medical applications.
In the 5V range, 3PEAK offers zero-drift amplifiers with up to 15MHz bandwidth and slew rates down to 5V/µs, as well as low noise levels down to 10nV/√Hz. All of these amplifiers are equipped with Rail-to-Rail Input/Output
In the following table you will find the most important parameters of the current portfolio in mass production:
