Low-Power Op Amp Line Gets Low-Noise Types

The popular LMV line of low-power, low-voltage operational amplifiers has been expanded to include ultra-small members featuring guaranteed low input voltage noise. Targeted for use in cell phones, pagers and other handheld products where low noise performance is a priority, the new ICs include the BiCMOS LMV721 single and LMV722 dual op amps housed in SC-70 and MSOP packages, respectively, and CMOS LMV751 residing in a SOT23-5 package. LMV721/722 op amps boast of an input voltage noise spec of
