This innovative single and dual op amp family builds on Cirrus’ patented Multipath™ amplifier technology, which completely eliminates the need to choose between low noise or low drift requirements. These powerful amplifiers deliver both! All devices provide excellent CMRR and PSRR and their common mode input range include the negative supply rail. Delivering excellent offset stability, very high open loop gain, and low noise below 1 kHz, performance is maintained over time and temperature. The CS3001/11 are single op amps that consume 2.1 mA and 0.9 mA, while providing 125 nVP-P and 250 nVP-P noise performance, respectively. The CS3002/12, dual op amps, consume 3.6 mA and 1.7 mA, while providing 125 nVP-P and 250 nVP-P noise performance, respectively. Process control, medical and test equipment, temperature measurement, and weigh scale applications are a few of the target markets that need these innovative operational amplifiers.
