High-precision operational amplifier

PREMA IC PR2201

The high-precision operational amplifier PR2201 runs with supply voltages up to 80 V (±40 V) and provides maximum output currents of ±6 mA.

Besides an outstanding common-mode rejection ratio (CMRR) and a power supply rejection ratio (PSRR) of more than 110 dB, the common mode input voltage covers almost the complete supply voltage range. Furthermore, the output voltage can reach the input voltage minus 1 V.

A low input bias current of 5 pA and an offset of ±2 mV allow the usage for applications with high precision required. (e.g. automated test systems). Due to the low standby current of 500 pA, generated heat is not an issue despite high voltages. Because of the high gain-bandwidth product and fast response time of almost 1 MHz and 1 V/µs, the PR2201 is appropriate for fast control loops.

The broad common mode input voltage range enables high ohmic measurements of smallest differential voltages at high potential (e.g. measurement bridges).

Dual-operational amplifier

PREMA IC PR2202

Equivalent to PR2201, PR2202 contains two operational amplifiers in one package.

Applications:

• automotive applications
• amplification of signals (measuring amplifier, encoder)
• audio applications (e.g. pre-amplification in microphones)
