The R2A20154 is an integrated circuit semiconductor of CMOS structure with 4 channels of built in D/A converters with output buffer operational amplifiers. It is the electrical characteristic ...

As the name implies, if we finally put together all the elementary blocks above (transistors, current mirrors, current sources, differential stages and buffers) we finally come to something usable, ...

Are your jellybeans getting stale? [lcamtuf] thinks so, and his guide to choosing op-amps makes a good case for rethinking what parts you should keep in stock. For readers of a certain vintage, the ...

New operational amplifiers optimized for high-performance audio and ultrasound applications combine extremely low total harmonic distortion plus noise (THD+N), -130 dB, with large output voltages on ...
