New Japan Radio has a wide range of precision operational amplifiers, with just a small selection highlighted below. They have designed their latest generation of op-amps for greater RF immunity, with revised schematics, paying particular attention to layout plus on-chip filtering. The result is less errors and noise, maintaining high performance in spite of growing interference sources such as Bluetooth, WLAN and GSM.
