The new CMOS operational amplifier family, the 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 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.
