CS3001/02/11/12

The CMOS operational amplifier family, CS3001/02/11/12, is designed to achieve optimum performance while reducing component count and bill of materials (BOM) costs. This innovative single and dual op amp family builds on Cirrus Logic's patented Multipath? amplifier technology to deliver both low noise and low drift. System noise is reduced by 10x and system drift by 4x compared to competing components.

CS3001/02/11/12 provide excellent CMRR (common-mode rejection ratio) and PSRR (power-supply rejection ratio) and a common mode input range that includes 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 and CS3011 are single operational amplifiers that consume 2.1 mA and 0.9 mA while providing 125 nV_P-P and 250 nV_P-P noise performance, respectively. The CS3002 and CS3012 are dual op amps that consume 3.6 mA and 1.7 mA while providing 125 nV_P-P and 250 nV_P-P noise performance, respectively.

Applications for these innovative op amps CS3001/02/11/12 include process control, medical and test equipment, temperature measurement and weigh scale applications.
